CV joint - a constant velocity joint or simply a "grenade" - is a very interesting and important detail. With its help, torque is transmitted from the transmission to the wheels. This part can be found on any modern front-wheel drive car.

The grenade is subjected to severe loads and is constantly in motion, therefore, since its invention, a large number of lubricating components have been invented aimed at reducing friction inside the CV joint, as well as preventing the formation of corrosion. Everything gets clogged with grease free space inside the CV joint, after which it is put on top protective boot(cover) preventing this lubricant from being washed off, as well as moisture, dust and sand from getting inside. Poor lubrication or leakage of the boot leads to destruction internal components this device, as a result of which the service life of the CV joint is reduced or its complete failure. Read about how to check the CV joint.

Considering the above, we can conclude that CV joint lubricant- is very important, so its choice should be taken seriously. In this article I will talk about how and by what criteria you should choose a lubricant for a CV joint, as well as what kind it is and what kind of lubricant for CV joint is better.

When asking how to choose a lubricant for a CV joint, you should be guided by the following criteria:

• Lubricant type;
• Interaction of lubricant with rubber and polymers (rubber bands, gaskets, seals, boots, etc.);
• Compound;
• Life time;
• Types of lubricants for CV joints;

There are many types of lubricants, including lithium, molybdenum disulfide, and barium lubricants. Now in more detail about each of them.

Lithium greases

Lithium solution based lubricants have yellow and thick consistency. At sub-zero temperatures lithium grease tends to get thicker. Because of this feature, these lubricating components do not begin to “work” immediately; as a result, in the cold, short-term knocking is possible at the beginning, until the lubricant warms up. This type of lubricant has proven itself and can reduce the load on components by up to 10 times.

It has increased conservation properties and almost does not allow moisture to pass to the metal surface of the part. Also worth noting is the decent dust neutralization. The fly in the ointment in this list of advantages is that not all lubricants of this type can boast excellent corrosion resistance. It is for this reason that it is recommended to check the condition of the lubricant after every 50 thousand km.

It is impossible not to note this important feature this type of lubricant is absolutely compatible with almost any polymers that are used to protect the working surfaces of CV joints. I mean the boot, gaskets and other rubber bands. The exception is plastic, or rather some of its types, when interacting with which this polymer can be destroyed.

Molybdenum disulfide greases

Lubricants based on molybdenum disulfide have recently begun to actively replace lithium lubricants for CV joints. There are several reasons for this, first of all, as I said above, lithium lubricants are contraindicated for some types of plastic that are used in modern cars. Besides, molybdenum lubricants for CV joints they have a longer service life, on average - 100 thousand km. It is for these reasons that lubricants of this type have recently become very popular among auto repairmen and motorists. The main advantage of these lubricants is their high degree of corrosion resistance. The level of friction is approximately the same as that of lithium analogues. Due to the special composition, in which the acid level is reduced, molybdenum lubricants practically do not interact with plastics and polymers.

One of the disadvantages is the fear of moisture. If moisture gets on the treated surface, it immediately stops “working.” For example, if the boot is damaged and inside the grenade water will get in, molybdenum grease will immediately lose its properties. Considering this feature, owners of cars on which it is used this type It is recommended to lubricate at least once a month or after an off-road trip. visual inspection CV joint boots for cracks, tears and other defects.

Barium lubricants

This type of grease can be called a worthy competitor to conventional lithium grease. Its peculiarity is that, like its molybdenum analogues, it is not aggressive towards polymers and rubber, however, unlike molybdenum disulfide lubricants, it is absolutely not afraid of moisture. The disadvantage is that the price of barium CV joint grease is quite high. The second "stone in the garden" - poor tolerance low temperatures, as a result, such lubricant will have to be changed after every winter, and this, as you understand, is an extra expense...

Let's summarize

Lubrication for the CV joint is vital, so monitoring its availability and condition is the task of every conscious motorist. In question what is the best CV joint lubricant? You should follow the recommendations of the manufacturer of your car, and also take into account the composition of anthers and other “rubber bands” that may be subject to destruction. In my opinion, the “golden mean”, that is the best option, can be considered lithium lubricants, provided that the anthers and other polymers are “not afraid” of this type of lubricant. If this option is contraindicated for you, pay attention to the second option - molybdenum lubricants for CV joints. They are not inferior in quality to the previous ones, but require constant monitoring and do not tolerate moisture, so make sure that the anthers are intact. The third option is suitable for those who live in warm climates where there are no harsh winters, since barium CV joint lubricants do not tolerate low temperatures. If finances allow regular seasonal replacement barium lubricant, then this option will be ideal in terms of characteristics and useful properties.

Going to the store to buy lubricant for the CV joint, I advise you to pay attention to the following manufacturers: Liqui Moly, BP, ESSO, Mobil and Texaco, as well as: Litol, CV joint-4, ShRB-4 and Fiol. The second group is represented domestic manufacturer, is not inferior in quality to foreign analogues and at the same time costs significantly less.

That's all I have, I hope the above will be enough for you to make your choice, I hope it will be the right one! All the best and see you again on the pages.

• ease and simplicity in production;
• CV joints provide uniform motion;
• Excellent maneuverability on slippery surfaces.

But at the same time front wheel drive cars there is a significant drawback - the transmission mechanism wears out quickly. To extend the service life, you should use a special lubricant for the components. Modern manufacturers offer a variety of lubricant materials. In order not to get confused and confused in the offered assortment, you need to know which lubricant for CV joints is better.

Attention! In addition to this, for quality replacement lubricant, you need to know how much lubricant is needed for the CV joint.

Requirements for lubricants for CV joints

The lubricant used in automotive mechanisms reduces friction of parts, which consequently prevents wear. Lubrication reduces the load on the mechanisms, makes them rotate more freely, and this allows the car to drive smoothly. Another positive point lubrication - reducing fuel consumption and transmission losses vehicle.

Modern lubricants are excellent rust preventatives. When rust appears in the CV joints, empty cavities appear, due to which transmission efficiency decreases, and a knock is clearly audible when cornering. Thanks to lubrication, corrosion does not occur, CV joints last a long time, and the motorist does not spend money on buying new parts.

An important property of the lubricant used is its gentle effect on organic and synthetic polymers. Since CV joints are protected from dirt and dust by rubber or plastic boots, the lubricant composition should not affect them.

Variety of lubricants

Manufacturers are constantly working to improve lubrication for CV joints. Over a long period since the advent of front-line and rear wheel drive Many different formulations have been developed. Each of them did an excellent job with its main function - reducing loads and friction in transmission parts. But some of them negatively affect polymer compounds and do not have an anti-corrosion effect. What lubricant should I use for the CV joint?

Attention! To choose the optimal lubricant, you need to know what types there are and the features of each of them.

Modern manufacturers make the following types of lubricants for external and internal CV joint:

• lithium;
• based on molybdenum disulfide;
• barium;
• mineral.

Lithium compounds

The most common and popular compounds are lithium. They are used for automotive mechanisms that are subject to increased loads, for example, for travel control. This material has a yellowish color and viscous consistency, made from a lithium solution, which is pre-foamed in an organic acid. The lower the temperature, the thicker the composition becomes and the harder it is to spread on the parts. This type of material perfectly prevents wear of parts, as it greatly reduces the load on the drive. In addition, they have a moisture-proof effect on parts and eliminate dust and dirt that gets inside.

Despite all the advantages of lithium compounds, not all of them can fight against pitting of CV joints. Auto mechanics recommend systematically checking the drive system every 50 thousand kilometers. The exception is the lithium-based product Litol-24. Experts recommend changing it after 100 thousand kilometers.

Lithium-based compounds do not affect most polymers used to make CV joints. But several automobile manufacturers Anthers are made from high-strength organic plastic. Litol and its analogues dissolve organic materials. When using such products, you should carefully read the instructions for them; it will indicate what means to use to protect them.

Today, the world leaders in the production of lithium compounds are Russian manufacturers. Abroad, preference is given to more modern technologies. Nevertheless, foreign lubricants for CV joints “XADO”, RENOLIT and others are still on sale famous brands.

Compositions based on molybdenum disulfide

The new generation of lubricants are compounds made on the basis of molybdenum disulfide. Unlike other types, these compositions provide reliable protection car mechanisms from corrosion. Tests show that after 100 thousand kilometers, CV joints do not have serious damage. But still, experts recommend replacing the lubricant after one hundred thousand kilometers or every five years.

Compositions based on molybdenum disulfide provide reliable protection of mechanisms from friction, and low content organic acids are not aggressive to the surface of polymers. Despite all the advantages, compositions of this type have one significant disadvantage - it loses its properties when moisture gets into the CV joint, and the consequence of this is destruction of the mechanism.

Therefore, when using products based on molybdenum disulfide, it is necessary to do a monthly preventive inspection of the anthers. In addition, there should be extraordinary inspections after driving on bad roads or after impacts on the bottom of the car.

Manufacturers of such compounds recommend using them in any car. When choosing a molybdenum disulfide-based lubricant, you should not be guided by price. Often, low-priced products are better than high-cost materials. An excellent option is the domestic CV joint lubricant-4, and among foreign analogues, experts recommend using Liqui Moly, ESSO, BP.

Barium-based lubricants

Barium compounds for CV joints have become an alternative to lithium and lubricants based on molybdenum disulfide. The main advantage of barium products is their high moisture resistance. You can also note such advantages of barium-based lubricant as anti-corrosion properties and neutral chemical composition, which is not aggressive towards anthers. The disadvantage of barium lubricants is their low resistance to frost temperatures.

Attention! Compositions containing barium have not yet become widespread, as they have sufficient high cost. Among domestic products, we can note ShRB-4, its foreign analogues are much more expensive.

Mineral compositions

Mineral compounds for CV joints provide reliable protection against corrosion and moisture. They perform excellently regardless of temperature. The lubricant is made from synthetic substances, lithium thickener, tackifying agents and rust inhibitors. The leader among mineral compounds is Chevron CV joint lubricant.

How to change the lubricant

To change the lubricant in CV joints, it is necessary to dismantle chassis cars. To do this, you need to remove the supports and ties, then move them to the sides shock absorber struts and remove the part.

To press lubricant into the CV joints, it is necessary to divide them into two parts - internal and external. Immediately lubricated inner part, for this it is separated from the drive mechanism. To prevent damage to the part, shallow notches should be applied to the body and support, which then need to be matched.

Then you need to use a thick rag or paper napkins to wipe the car to remove the old lubricant and apply new lubricant. After this, you can proceed to lubrication of the outer CV joint. It also needs to be cleaned of dirt.

Many motorists have a question: how to wash the CV joint from old grease? Experts recommend using by special means, and do not use soap or car shampoo for this. The washed parts should be wiped with a napkin and filled with lubricant. After that outer boot The CV joint with lubricant is installed back on the car.

Another logical question is how much lubricant should I put in the CV joint? The weight of the lubricant for the CV joint needle bearings is approximately 115 g, and for the external unit - 135 g. This can be determined visually as follows - on the outer part of the part the lubricant should slightly extend beyond its limits, and on the inner part it should not reach the edge by about 0.5 cm.

How to fill the CV joint with grease can be seen in the video:

Rotational power moments from vehicle transmission units to the wheels to equalize angular velocities, special joints called CV joints and a tripod with mandatory lubrication are used.

Cars of specific brands have different kinds devices that ensure rotation of the drive axle shafts at the same speed. It does not depend on how sharply the steering wheel is turned or on the position of the vehicle's suspension system.

The CV joint consists of two autonomous units:

• the internal assembly is attached directly to the drive axle;
• the second is integrated into the drive wheel hub.

They are used for leveling angular velocity large balls, moved along special grooves. Depending on the car model, a specific lubricant is used for the internal CV joint and external analogue. The disadvantage of the mechanical design is that it does not provide for axial movements of the suspension. Needle joints have these properties.

They were called tripods, from the English word tripod. Hinges of this type compensate for the lack of ball analogues. The angular velocity is equalized due to the movement of the rollers along special channels during turns or axial instability.

Since the inquisitive thoughts of engineers do not stagnate, CV joints with hinges were created ball mechanism, allowing you to create axial movements. As an example it is worth citing domestic car Volzhsky Automobile Plant modification 2108-2110. They were produced with a needle version and a ball version.

What kind of lubrication is required?

It should be understood that the conversation is about the leader front axle, since the driving axle equalizes angular speeds using a differential. CV joints operate under enormous multidirectional force moments in an elevated temperature zone. In order for the tripod to function for a long time, the component parts should be lubricated.

The required paste-like consistency is integrated into the assembly and carefully sealed with reliable anthers. They can be plastic or made of rubber.

A mandatory condition is to never, even in great need, use lubricant that is at hand. The recommended type of lubricant will ensure long-term operation of the hinges.

The unit with ball working elements is lubricated with products with universal extreme pressure characteristics that can work for a long time in areas of elevated temperatures.

A similar condition is set for tripods (a unit with needle rollers), which require that the lubricant product does not contain solid particles with abrasive characteristics in its consistency structure. The use of a non-specific lubricant is a direct path to the destruction of important components for cars. Use of non-recommended graphite lubricants, leads to a rapid exit of the hinges from the functional state.

Drivers make a serious mistake when they use lubricant intended for ball joints to lubricate a needle roller joint.

Types of lubrication

In specialized online stores and standard retail outlets, you must buy lubricants with the abbreviation NLGI 2 on the packaging.

Consistencies contain extreme pressure additives MoS2 (molybdenum disulfide). The lubricant actively resists wear of the hinges under instantaneous force impacts, when welding of moving balls along structural grooves is possible. Practice has shown that lubrication of the hinge ensures its long-term operation.

It is easy to recognize a lubricant containing molybdenum disulfide by its appearance. Consistencies are presented with a black or gray-dark sheen.

The lubricant packaging material contains the following inscriptions:

• for ball CV joints;
• MoS2;
• with molybdenum disulfide;
• CV joint-4 (lubrication domestic production).

In retail, wholesale There are other proposals that deserve the attention of motorists. The main thing is to choose the right lubricant to soften the abrasiveness of the rubbing parts of the hinges, which has a good effect on the functionality of the working part.

Lubricants for tripods

The design features of tripods, where the main wear elements are needle-type bearings, require the use of other brands of lubricant.

Practice has proven that it is better to use lubricating consistencies that contain the following inscriptions on the packaging:

• NLGI 1;
• NLGI 1.5;

The products presented do not have any solid additional inclusions. In the context of the instructions, it is said that for this type of hinges it is impossible to use lubricant under the sign “CV joint-4” and other analogues containing molybdenum additives in the structure.

Vehicle operational practice proves that it is better to buy and use the following lubricants:

• Tripod Joints;
• "For pods";
• Inboard;
• Inner and others.

The list of lubricants is long. It is physically impossible to list commercially available items in text. Imported lubricants are easy to buy at numerous stationary retail outlets and online stores. Today, universal tripod lubricant is a marketable imported product due to its high technological characteristics.

Lubricants requiring detailed clarification

Liquid marketplaces offer products that require clarification on where they can be used. That is, lubricants for the internal component, tripod, or used as a universal product.

• First on the list for analysis is a lubricating consistency called RedLine CV-2, containing red molybdenum. The instructions for use explain what the material contains molecular structure organic molybdenum atoms. On English language the statement is accompanied by the phrase Red Moly.

There are different interpretations on lubrication forums. Others praise how cool she is! Others take the lead, proving that they are only suitable for ball joints. Opinions are opposite, but not critical in terms of emotional intensity, which ultimately leads to a neutral conclusion - it can be used for ball joints and for pods.

Polyurea based lubricants

Promotional videos of manufacturers of lubricants for special automotive components, attract the attention of motorists. Of particular interest are lubricants made with polyurea. First, let's decipher the complex name, that is, what it means.

These are synthetic polymers, the structure of which contains particles of the product (urea). Substance presented chemical formula NH-CO-NH. Polyurea lubricant creates a special anti-seize protective film.

• The Slipkote® Polyurea CV Joint product is manufactured using this technology. Used to lubricate joints and parts that equalize angular velocities. It is used in cars with a driven front axle, in cars selected models with rear driving axle.

Lubricate the unit for the entire service life. Changed during maintenance. This lubricating consistency has a number of advantages over other analogues. Grease holds high temperatures, does not destroy thermoplastic, waterproof. Polyurea thickener in sublimation with basic lubricating consistencies, non-traditional additive materials, guarantees durability and resistance to uncomfortable conditions of use.

When using this lubricant, it is necessary to systematically monitor the joints for the possibility of fluid leakage.

Domestic manufacturers

In Northern Palmyra, production of an assortment of VMPAVTO lubricants has begun. New product called “MS-CV joint tripod”. The instructions for use state that the lubricant is recommended for universal use at temperature conditions up to +160 C°. Other positive information is also given. Little has been said about the shortcomings.

Manufacturers of VMPAVTO lubricant “forgot” to describe in detail specifications product. It seems that the buyer must take the seller's word for it. To some extent, the mistake of a branded enterprise is not clear to customers.

The product sold does not mention whether it has been lubricated test test. What side inclusions are integrated into the consistency? The lack of basic product descriptions cannot but alarm buyers. They want to know almost everything about the domestic VMPavto product.

Lubricant for CV joints exists for good performance of the hinge at equal angle speeds, reduces the level of rubbing, increases the efficiency of the system and prevents rust from forming on some parts of the hinge. Many car owners are wondering what lubricant to use for CV joints? We have selected for you the material and their functions for comparison, which are in the range of lubricants. Also in the text we provide information for their use in practice, and what people say based on personal experience of using the six most common lubricants by many drivers.

We will look at these aspects:

• types of CV joints and the necessary qualities for lubrication
• Types of lubricants used for angle speed joints
• type of lubricant used in harsh conditions
• how to change the lubricant in a CV joint
• lubricant models for internal and external CV joints
• the best lubricant

characteristics of CV joints, its properties and varieties

Before moving on to describing the properties of lubricants, let's talk about CV joints. This is necessary in order to know what qualities lubricants for “grenade” lubricants should have, as CV joints are popularly called, and what composition to use in certain cases. The hinge exists in order to transmit torque from one axis to the second if it is located at an opposite angle. The value can reach up to seventy degrees.

Over the course of the existence of CV joints, the following were made:

Ball. These are the most popular, specifically their analogue “Rtseppa-Lebro”.

Tripod(Tripod). They are often used in the Russian automotive industry as internal CV joints (those that are installed on the side of the power drive).

Classic tripod

Crackers(they are also called cam ones). They often get hot, so they are installed in trucks where the rotation angle is low.

Cam-disk. These are also installed on trucks and construction vehicles.

Paired cardan shafts . Typically used on construction equipment and trucks.

At significant angles in the middle of the axes, the effect of the hinges decreases. In other words, the value that transmits the torque of the joint is smaller. Therefore, avoid heavy loads with the wheels deployed.

A special feature of each angle velocity joint is the large impact loads. They appear when the car starts driving, climbs, rides over potholes, etc. Special lubricants CV joints neutralize all bad consequences.

The current hinges work at the same angle speeds a lot (if you maintain the tightness of the boot), and even as long as the car will drive. The lubricant must be changed when replacing the boot or the entire CV joint. Although according to the manual, changing the CV joint lubricant should be done after 100,000 km of driving or once every five years (whichever is required earlier).

Characteristics of lubricants for joints of equal angular speeds

Since it is difficult conditions operation of the hinges, CV joint lubricant in order to protect the system from negativity and provide:

1. Increased coefficient of rubbing of parts inside the hinge;
2. Minimizes wear of some parts of the CV joint.
3. Will reduce the mechanical load on the component parts.
4. Protects the surface of metal parts from corrosion.
5. Neutral reaction with rubber joint seals (boots, gaskets) in order not to spoil them.
6. Repels water.
7. Long lasting use.

Based on all of the above characteristics, CV joint lubricant should have the following properties:

1. Wide temperature Range, which will allow the substance to be used at extreme temperatures (current lubricants are capable of functioning at degrees up to minus forty and plus one hundred and forty and higher, this level will depend on the type of lubricant).
2. High degree of adhesion (it must be able to adhere to the mechanism, otherwise it will be sticky).
3. Mechanical and physico-chemical. stability of the composition, which will ensure uninterrupted lubrication processes under all vehicle operating conditions.
4. High anti-seize properties that will provide the required level of slipperiness for lubricated surfaces.

Thus, the properties of a self-propelled CV joint must withstand the above requirements. Today the industry produces many varieties with this composition.

Types of lubricants for CV joints

Lubricants are produced on the basis different compositions their facial elements. Let us present and write the properties of the currently used types.

LM47 lubricant for CV joints with molybdenum disulfide

Lithium CV joint greases

These are the oldest lubricants, they were used immediately after the invention of the hinge. They contain lithium soap and various thickeners. Their color varies from light yellow to light brown, it all depends on base oil lubricant that was used. They are suitable for use at normal and maximum degrees. But in cold weather, viscosity is lost, so the mechanism is not protected as it should. Maybe even the hinges will tap in severe frost.

Regular Litol-24 is also made from lithium lubricants, but it cannot be poured into CV joints.

CV joint lubricant with molybdenum

As technology developed, the use of lithium greases became less people. Therefore, the chemical industry has developed improved lubricants based on lithium soap, but with the addition of molybdenum disulfide. If we talk about the properties of the lubricant, they are similar to lithium analogues. But the peculiarity of lubricants with molybdenum is that they have great anti-corrosion properties. This was achieved by using metal salts in the composition, replacing a little acid. These substances do not pose a danger to the rubber and plastic from which some CV joint parts are made, specifically the boot.

Usually, when you purchase a new boot, it comes with a bag of lubricant. As a rule, it may be a fake. Therefore, before using it, you need to check its composition by pouring a little onto a piece of paper. If it is not thick or raises doubts, buy another lubricant.

The big disadvantage of molybdenum lubricants is that they are afraid of moisture. If a little water gets under the boot, the lubricant can turn into an abrasive with consequences (parts inside the CV joint are damaged). Therefore, if you use molybdenum lubricant, constantly check the type of boot on the CV joint frame and its sealing.

There are such bad sellers who say that a self-made joint with molybdenum will restore a broken unit - these are bikes. If there is a crunch in the CV joint, you need to carry out renovation work or replace it at a service station.

Well-known types of products from this series in Russia are lubricants CV joints-4, LM47 and others. We’ll talk about their pros and cons below, as well as compare them.

Barium grease ShRB-4

Barium lubricants

This type of lubricant is the most modern and technologically advanced today. Lubricants with excellent performance properties, chemical resistance, are not afraid of water and do not interact with polymers. They can be used as a lubricant for CV joints inside and outside (tripod).

Minosom of barium lubricants - decreased functions in cold weather. Therefore, they need to be replaced every spring. Since production is complex and technologically advanced, the cost of these lubricants is higher than those similar to those based on lithium or molybdenum. The most famous Russian lubricant this variety is ShRB -4.

CV joint is a system that operates in difficult conditions. Therefore his lubricant must be excellent quality. Specifically, the CV joint should not be lubricated:

• grease on graphite
• technical Vaseline
• "Grease 158"
• different hydrocarbon compositions
• compositions based on sodium or calcium
• compositions based on iron and zinc

How to use lubricants at low temperatures

Many drivers from the North of Russia are wondering what lubricant to choose that would not freeze in extreme cold (for example, minus 50 - minus 40). You need to decide by reading the information provided by the manufacturer. This is important and applies not only to CV joint lubricants, but also to all oil substances and liquids that are poured into cars in the North.

Before driving in cold weather, we advise you to warm up the engine very well so that the oils and fluids, as well as the CV joint lubricant, warm up and are in working condition. Otherwise, what will happen is that the mechanisms will wear out and fail faster.

As drivers who live in the north say, Russian lubricants are good “and RAVENOL Mehrzweckfett mit MoS-2. We'll talk about what to choose later.

Changing the lubricant in CV joints

The process of changing the lubricant in the joint of equal angle speeds usually does not lead to difficulties, even if there is no experience in car repair. First you need to remove the CV joint from the car. The order in which you proceed will depend on what kind of machine you have. That's why we don't give specific advice. Also, do not forget that there are external and internal hinges. Their work is completely different from each other. We won’t go into details, but let’s say that the basis of the external CV joint is balls, and the basis of the internal one is rollers or bearings with needles. CV joint, which is inside, with large axial movements. Various lubricants are used to lubricate the inner and outer joints. We will show an example of a change on a CV joint tripod, since this is the most popular.

Before changing the CV joint lubricant, know how much you will need. This material will be in your car's manual. Although this information is often neglected, and drivers pour a lot of tripod into the glass. When you take out the CV joint, the changing process follows this principle:

How much CV joint grease is in a “glass”

1. Let's disassemble the body. Often the frame is secured with 2 stopper rings (rolled). And of course, in order to dismantle it, you need to remove these rings with a screwdriver with a straight blade.
2. Remove the boot and seal rings. After completing this task, you should check the boot for integrity. If necessary, buy a new one for installation.
3. Afterwards you need to take all the mechanisms inside the hinge and dismantle them. The tripod itself is held on the axle shaft by a stop ring; gently remove it. You will need a screwdriver.
4. Wash everything thoroughly in gasoline or solvents, the parts that were inside (tripod, rollers, semi-axle) in order to remove the old lubricant. The glass inside also needs to be cleaned of it.
5. We put a little lubricant (about ninety grams, although this figure will vary depending on the CV joint model) in a cup. We will find out which lubricant to choose for the tripod later.
6. Let's place the tripod on the axis in the cup, in its functional place.
7. We add the lubricant on top of what is left on the placed tripod (as a rule, tripods contain approximately 120-150 grams of lubricant). Place the lubricant evenly by rotating the tripod axis in the frame.
8. Then we proceed to assembly, which is carried out in reverse disassembly sequence. Before tightening the rings or clamps, lubricate the grooves with lithol-24 or other lubricant.

Replacing the lubricant on the inner CV joint

As you can see, the change process is easy, it can be done by every driver who has the simple skills of a locksmith. The main task is which type of CV joint lubricant is better and why? Now let's try to answer these questions.

Application of lubricants for CV joints

Since the designs of the hinges, inside and outside, at the same angle speeds are different, the lubricants for them must be different. Specifically, for the CV joints inside, we use the following lubricant models:

• Mobil SHC Polyrex 005
• Slipkote Polyurea CV Joint Grease
• Castrol Optitemp BT 1 LF
• BP Energrease LS-EP2
• Chevron Ulti-Plex Synthetic Grease EP NLGI 1.5
• VAG G052186A3
• Chevron Delo Greases EP
• Mobil Mobilgrease XHP 222

• Liqui Moly LM 47 Langzeitfett + MoS2
• Very Lube LITHIUM LUBRICANT FOR CV joints MoS2
• Mobil Mobilgrease special NLGI 2
• BP Energease L21M
• XADO CV joint
• Chevron SRI Grease NLGI 2
• Mobil Mobilgrease XHP 222

The best lubricant for CV joints

We found on the Internet the opinions of specific drivers about popular lubricants for CV joints, then subjected them to analysis. I hope this material will be useful to you and will answer the question - what is the best lubricant for CV joints? The opinions are shown in the table, as they go indicating their popularity, from strong to small. So we selected the five most popular CV joint lubricants:

Domestic lubricant CV joint-4

A lubricant produced by several domestic enterprises. It was made for use in 1 Soviet VAZ-2121 Niva. After that, they began to use it for front-wheel drive VAZs. In addition to being used in bearings with CV joint balls on the outside, grease can be used to lubricate parts of carburetors, telescope struts, and clutch bearings. CV joint-4 - mineral lubricant based on aqueous lithium xystearate. Its temperature properties: operating degrees - from -40°C to +120°C, dropping degrees - +190°C. The cost of a tube is 100 g. will cost one or two $, and a tube of 250 grams will cost two or three $. Catalog license plate - OIL RIGHT 6067.

Liqui Moly LM 47 Langzeitfett + MoS2.

Likyu Moli LM 47 Langzeitfett + MoS2. The lubricant has the appearance of a thick a plastic substance of a dark gray, almost black color, produced in Germany. The lubricant contains a set of lithium (as a thickener), an oil-on-mineral base, a set of additives (also against wear), and hard lubricant particles that reduce chafing and wear. It is used in CV joints on the outside. In addition, it can be used when servicing electric tools, printing houses and agricultural, construction machines to lubricate the threaded part of guides, spline shafts, high-load hinges and bearings. Operating degrees - from minus 30 to plus 125. Cost of one per 100 grams. - four to five dollars (license plate LiquiMoly LM47 1987), and 400 gr. - (LiquiMoly LM47 7574) will cost nine to ten dollars.

Ravenol Mehrzweckfett mit MoS-2 RAVENOL brand stagnations are made in Germany. Molybdenum disulfide, which is contained in it, extends the operating time of CV joints and reduces their level of wear. Lubricant resistant to salt water. Degrees of use from minus 30 to plus 120. The cost of one is 400 grams. about five or six dollars. In the catalog you will find this product with number 4014835200340.

CV joint MS X5

CV joint MS X5. Also domestic brand. Composition class according to NLGI - two thirds. Classic 2 has a penetration range of 265-295, the lubricant is not very hard. It must be said that types 2 and 3 are usually used for bearing lubrication (specifically, type 2 is more common among lubricants for lubricants). The color of the lubricant is black.

Bottom line

Carry out the process of changing the lubricant of the joint of equal angle speeds according to the recommendations given by the manufacturers of your machine. Remember, it is cheaper to purchase lubricant for the CV joint than to repair or replace the joint itself due to breakdown. Therefore, do not neglect this. If we talk about choosing a specific model, he recommends not to go for the apparent benefit and not to take low-cost lubricants. For this money you can buy a good product. I hope that this material was useful to you, and now your decision - what to buy - will be correct.

With the onset of autumn, drivers will have to face some problems on the road and in car operation. Below we present several useful tips from experienced motorists.

In autumn the time of rain begins. The road becomes slippery. Therefore, you need to move more carefully.

When approaching a puddle, you should slow down. This way you will leave the clothes of pedestrians clean and also preserve the wheels of your car. Who knows what's hiding under the water.

You need to be especially careful near educational institutions.

Monitor tire pressure. This is especially important in the fall.

Check the battery condition. After all, in cold weather the reliability of the battery is especially important.

Think now about winter tires. It is also worth preparing your car for winter by checking the anti-corrosion coating.

Review the content luggage compartment. Replace summer accessories with autumn-winter ones.

Write in the comments how you prepare your car for use in the autumn-winter period.

Uzbek-made Ravon cars will be used by Russian law enforcement agencies.

This information was provided as part of a dealer conference in Moscow, which was held in honor of the start of sales of brand cars on the Russian market.

The event participants were shown updated sedan R4, used in Moscow traffic police. The car differs from the standard version in its unusual livery, as well as the presence of additional functions intended for law enforcement officers.

What is the best lubricant for CV joints and why is it needed? Front-wheel drive cars have a number of advantages over rear-wheel drive cars. Production front wheel drive cars simpler, they are resistant to skidding on wet and snowy surface roads. But in addition to the advantages, these cars also have disadvantages, these include the use of a constant velocity joint in the car drive, which ensures confident movement.

CV joint is a part that contributes to rapid wear transmission. To extend life, it is necessary to use a specialized lubricant for the outer and inner CV joints, which increases the wear resistance of the CV joint and transmission components. Today a huge number various lubricants and car owners have to rack their brains over the question of which lubricant option will best lubricate CV joints and their joints before choosing the right one.

What functions does a lubricant perform?

Motorists know that lubricants used in car components and joints not only reduce friction and prevent premature wear machine parts. But they also reduce the load on the parts, as a result of which the parts rotate freely and the car continues to move without friction or load.

CV joint lubrication allows you to reduce fuel costs and losses in transmission operation. Quite a lot important property is to prevent the spread of corrosion. It is during corrosion that the operation of CV joints is accompanied by the appearance of an unpleasant knocking noise, which intensifies when the steering wheel is turned and torque is not transmitted effectively. To prevent CV joints from getting dirty, boots are used. It is important to prevent grease from getting on the boots; they are made of rubber or plastic, which is eaten away upon contact with grease.

When does the CV joint lubricant change?

The lubricant is replaced in the following cases:

• torn boot and its replacement;
• replacing the angular velocity adjustment hinge;
• CV joint operation for more than 5 years;
• mileage over 100 thousand kilometers.

Do not apply a large amount of lubricant, this will not give better protection, but will only increase the likelihood of spoiling the anthers. There should be enough lubricant so that the part is completely lubricated and no grease drips from it.

How much grease should I fill into the CV joint? It all depends on whether it is indoor or outdoor. For an internal CV joint, 100-110 grams is enough, and for an external CV joint, 70-80 grams.

Types of lubricants

Along with the question: which CV joint is better, motorists are faced with the problem of choosing a lubricant. There are many different lubricants for caring for CV joints and each has its own advantages and disadvantages. Here we will consider only those that have proven themselves and are considered most suitable.

Lithium based greases

The most common lubricants are lithium foam lubricants in organic acid. These lubricants are yellowish in color and slightly thick. In the cold they thicken even more, as a result of which spreading them on the part becomes a little problematic. This problem makes itself felt at sub-zero temperatures at the beginning of driving - you can hear the tapping of the CV joints and suspension. When all the mechanisms are warmed up, the car's operation is improved. Such lubricants reduce friction well and reduce the load on components by up to 10 times.

The big advantage is the neutralization of trapped dust and the ability to prevent moisture from reaching the parts. Another feature lithium greases is that they are fully compatible with the polymers that are installed on CV joints, with the exception of some hard plastics that are present on modern cars.

The disadvantage of lithium greases is that most of them have poor corrosion resistance. This is what you need to pay attention to first when choosing this type of lubricant.

Lithium-based lubricants can be used such as Litol-24, Renolit, Xado. These lubricants have already proven themselves on the market and have the most suitable properties.

Molybdenum disulfide based lubricants

Due to the fact that the lithium option is not suitable for all cars, engineers had to look for a way out. The solution to the problem was a lubricant to which molybdenum disulfide was added. Thanks to this connection, the lubricant for CV joints has acquired high corrosion resistance. In addition, the amount of acid in the lubricant is reduced, which reduces the level of interaction with solid polymers. Thanks to this, it became possible to use such a lubricant on any modern car.

If we consider resistance to friction, then in this feature lubricants based on lithium and molybdenum disulfide are almost the same. But still, the molybdenum disulfide product contains big drawback. The lubricant completely loses its properties after water gets under the damaged boot. To prevent this from happening, you need to inspect the condition of the anthers at least once a month. You should also look under the car after heavy impacts on the suspension and off-road driving.

Such lubricants are produced by the most different manufacturers. Shrus-4 lubricant, produced domestically, is not inferior to analogues from other countries, it works no worse. From foreign ones, you can use such lubricants as Mobil, BP, Liqui Moly, Esso.

Barium based lubricants

Recently, scientists have created many different lubricants for CV joints, but only one type combines the advantages of lithium and molybdenum without their disadvantages - barium lubricants. The main advantage of such lubricants is their high resistance to moisture. For example, if the boot ruptures, the barium-based lubricant can not be changed until a lot of dirt has accumulated in it.

Equally important is that such barium grease protects CV joints from all types of corrosion and does not dissolve boots made of any polymers. The only thing that this type of lubricant cannot boast of is the price and low resistance to negative temperatures. Barium-based lubricants are much more expensive than lithium and molybdenum lubricants due to the complexity of their manufacture and are much less common.

On the market you can find only one domestically produced barium-based product - ShRB-4.

What lubricants should not be used

Under no circumstances should lubricants be used on the following bases:

• graphite (serve to protect bearings);
• hydrocarbon;
• zinc;
• calcium;
• sodium;
• iron based.

They will simply lead to the destruction of the mechanism.

How to choose a lubricant

Lubricating CV joints have different lubricants appearance. Considering all the features and internal set of characteristics of lubricants, the most suitable option, today, these are molybdenum disulfide-based lubricants. A good option, suitable for all vehicles, minimizes friction in components and is resistant to corrosion, with minimal impact on the boot. By lubricating each CV joint unit, you will extend its life. But still, when choosing a lubricant, you should follow the recommendations in the instructions for your car.
