The shock absorber strut is a very important part of the car that should be protected from damage. Few new drivers know what exactly reliable protection The durability of this part depends. The shock absorber strut boot plays important role, as it protects against dirt, small particles and dust. Replacing it requires knowledge of the structure of the car and an understanding of how this part of the car works. In this article we will analyze in detail the functionality of the racks, necessary protection for them we will bring quick guide for replacing shock absorber bumper boots for the strut.
Depending on the type of vehicle, the shock absorber and spring can be attached separately or together. The design under consideration is called a shock absorber strut and performs the main function of smoothing the movement of the machine.
If your car moves smoothly and does not throw up passengers and the driver, then the shock absorber is in its place and it is selected correctly.
Based on this, the main functions of shock absorber struts include:
- Maintaining constant contact of the wheel with road surface. This point means that the car will not swing up and down after hitting a bump; the stand will be able to reduce these vibrations to zero in a matter of seconds.
- Minimal feeling of unevenness on the road by the driver and passengers of the car. This means that the stand creates comfort for traveling even on bad roads.
- Safety of the driver and all vehicle passengers. The stand performs protective functions and makes the car more manageable. In unforeseen situations, emergency situations, it helps the driver maintain the chosen direction of movement.
Tool
To ensure that the replacement of the shock absorber bumper boots that protect the mechanism is carried out quickly and efficiently, it is not necessary to contact highly qualified specialists at the station Maintenance, you can perform all operations at home. To do this, it is worth studying the design of the car in detail and preparing all the parts, tools and spare fasteners.
Be sure to prepare:
- dustproof shock absorber kit, which will include a boot bumper, fasteners for them and the necessary equipment;
- keys different sizes(possible from the extended motorist set);
- sliding key (just in case you don’t have the right size key);
- a set of tools for removing wheels (these should be spring ties, screwdrivers, nuts, keys);
- another additional tool that may be needed depending on the car model.
The shock absorber dust kit can be original (from the manufacturer), universal (which supposedly fits all types of cars) or replacement (a cheap counterfeit version that is similar to the original). The car development company always recommends using only original parts, since only they can work reliably and for a long time. In part, this is a correct statement, since only the manufacturer knows all the ins and outs of your make and model of car. But such original parts from the manufacturer are expensive and for this amount you can buy several replacement or universal kits.
In this case, the choice is only up to the car owner, but it is worth considering the fact that when installing non-original parts, you should be as picky as possible about the shock absorber bumper boot. If you choose something that is not exactly the same, it will burst very quickly and the stand will be unprotected, and this threatens rapid wear and expensive replacement of shock absorbers.
How to replace - step by step
The dustproof shock absorber kit should match the strut and car model as closely as possible. If it is chosen correctly, you can forget about the incomprehensible sounds of the rack for several years. So, if everything is already prepared, let's get to work:

The shock absorber boot is a very important part of the car. It is better to tinker with replacing it than to later deal with the consequences of a damaged shock absorber. Every caring driver knows about this, so he will visit a service station more often to check the integrity of car parts.
Always be attentive to your iron friend, assistant and carrier, because your car also needs to be treated warmly and with care. Good luck in the difficult engineering business!
Video " Replacement of rear shock absorber bump stop boots”
In the video, a car enthusiast shows how to properly replace shock absorber bumper boots. After watching the recording, you can repeat each replacement step yourself.
One of the most frequent repair operations performed by our car service technicians is to repair the chassis vehicle, is a replacement CV joint anthers, both for preventive purposes and during the repair of this unit. The frequency tells us that this seemingly insignificant problem requires close attention and a timely solution.
In company " Maximum Security» the inner and outer CV joint boots are being replaced at the most favorable conditions: with a guarantee of the quality of all work carried out, using the most modern high-tech equipment and high-quality Supplies, as well as in the shortest possible time and at an affordable, competitive price for St. Petersburg!

Replacing the CV joint boot - a few words about the element
CV joint is a joint of equals angular velocities(it is also jokingly called a “grenade”). It transmits torque at wheel rotation angles up to 70º from the longitudinal axis of the vehicle. Most often, CV joints can be seen as part of the front independent suspension(less often - in the back).
Today, the most popular and widespread is the ball CV joint (type “Rzeppa”, “Birfield” or “Bendix-Weiss”), consisting of 6 balls, an inner and outer ring with slots for them. The rings are connected to drive shaft through spline connection. also in CV joint design includes a separator that holds the balls.
Such a number of elements categorically does not tolerate the presence of dust, which sharply increases the friction force of parts and leads to catastrophically rapid breakdown of the unit. Therefore, the CV joint is immersed in a sealed rubber cover, corrugated for better mobility - the so-called “boot”. And in most cases, the health of the entire joint depends on the integrity of this anther.
There are usually 4 of these “grenades” located on the front suspension:
- Two internal (left and right) for installation in a box;
- Two external ones (also right and left) for installation in wheel hubs.
Accordingly, in such cases there are also 4 boots for CV joints (two internal and two external).
Replacement - outer CV joint boot - a little theory
To replace the outer ball boot, you will need to lift the car on a lift and remove the front wheels. Then you will have to loosen the hub nuts, which requires enormous effort or special tools and skills. Next you need to unscrew the ball from lower arm and remove the CV joint from the wheel bearing. Replacing the boot of an outer CV joint is a rather labor-intensive operation, and therefore it is better to carry it out in a well-equipped car service center and by experienced craftsmen who can guarantee not only the correct dismantling of failed parts and the installation of new ones, but also the competent, reliable reassembly of the entire assembly.
Replacing the inner CV joint boot - brief description
Anther internal CV joint It loses its tightness extremely rarely, because it is almost completely protected by the parts of the box. However, there is a need to replace it. Same as with the rubber boot outer CV joint, replacement internal boot“grenade” is accompanied by lifting the car, removing the wheels and partially disassembling the chassis, including removing the CV joint from the hub and completely disassembling the joint for thorough cleaning.
Without special knowledge and skills, it is extremely problematic to accurately select the boot of the internal CV joint, its proper installation and correct reassembly of the entire assembly (it is especially important to insert all the joint balls into their places). That's why replacing the boot internal CV joint should be entrusted to professionals and carried out in a car service center.
Steering rack boot - replacement and meaning of these simple elements
The steering rack is very important detail the chassis of the car, which directly affects its handling. One of the reasons for its failure may be excessive penetration of moisture and dirt into this unit and displacement of lubricant from it, which will rapidly accelerate its premature wear. To protect against such trouble and prevent expensive repairs To replace the steering rack, a special boot has been developed - a sealed rubber casing that protects the connection from dirt and moisture and from lubricant leakage.
Such a casing is by no means eternal and during operation is subjected to various mechanical loads, which ultimately leads to its depressurization. And then you urgently need to install a new steering rack boot - replacing this small and inexpensive part, carried out in a timely manner, can save you thousands of rubles, or even US dollars, on serious repairs to the chassis.
Replacing the shock absorber boot and strut - the suspension does not forgive carelessness
Timely replacement of the strut boot is the key to the durability of this suspension element, because this simple rubber or plastic part reliably protects it from dirt and moisture and premature wear. The same can be said about replacing a vehicle's shock absorber boot. However, despite the primitiveness of these small rubber covers, replacing them is a rather labor-intensive operation that requires a clear understanding of the car’s structure and some tools.
In particular, to replace the strut boot you will need:
- Raise the car on a lift (or as a last resort, jack).
- Unscrew the rod nut and knock its fastening down.
- Push the rod in until it stops.
- Remove the worn boot through the spring.
- Place the new boot on the stand.
- Ensure the correct direction of the rod to its original location.
- Lower the machine and tighten the rod nut back.
This is just one way to replace the front strut boot (a similar operation can be done on the rear one). Also replacing the boot brake caliper or shock absorber will require not only manual dexterity and special knowledge, but also the appropriate equipment and qualifications of the craftsman. Therefore, it is better to carry it out in a certified car service center that has proven itself in St. Petersburg, for example, Maximum Security.
Replacing the boot - price and other advantages of contacting Maximum Security
In our service centers You can order a service such as replacing the boot - the price of this procedure will be disproportionately lower, as well as the time losses, than when repairing a unit that has failed due to the depressurization of this small rubber element and dirt and moisture getting into metal joints.
In addition to the price of replacing anthers various nodes(CV joints, shock absorbers, brake calipers, struts, etc.), the advantage of our company is the high qualifications and experience of our craftsmen, allowing them to cope with a task of any complexity in the shortest possible time.
Replacing anthers - signs of the need for this procedure
There are a number of symptoms that indicate that you need urgent replacement shock absorber boot, strut, brake caliper or CV joint:
- Visual violation of the integrity of the corrugated rubber band (look with the wheel turned out too far);
- Traces of splashed lubricant around the CV joint boot;
- Also, a faulty CV joint boot will make itself felt by sound - on sharp turns a characteristic crack will be heard;
- Excessive vertical rocking of the machine when pressing on it from above may indicate the need to replace the shock absorber boot or struts;
- Uneven wear brake pads may indicate the need to replace the brake caliper boot.
The symptoms described above signal the need to take active steps to eliminate the problem as soon as possible. Otherwise, this seemingly insignificant “disease” may turn into a long and expensive “treatment” for your “ iron horse" In a word, replacing CV joint boots - internal and external, shock absorbers, struts and calipers should become a useful habit for every car owner. Then it will be possible to significantly extend the trouble-free service life of the car and prevent its serious breakdowns!
In the previous article about anthers, we looked at the main options for their use, and also determined their necessity, significance, and the consequences of their destruction.
There are other parts that have protective covers(anthers), which are definitely worth talking about. For example, boots of struts (shock absorbers).It so happened that initially the article was conceived specifically about them, but when writing it was necessary to give a detailed definition of anthers as a whole, which ultimately gave rise to a huge article that had to be divided into two parts. So, the rack boots.
These boots are somewhat similar in appearance to the steering rack boots, but are installed on the racks. It is the reliability of this boot that often determines how long the strut lasts on a car.
So what does the strut boot protect? Paradoxically, the rack, or rather its upper part, where the working part of the rack moves up and down, is its rod. This entire structure without anther becomes completely defenseless against dirt, dust and water - the moving rod will catch microscopic particles of dirt and drag them inside the body, breaking the entry point, the oil seal located in it, which leads to a breakdown of the strut and the release of gas from it and oils.
You often hear the phrase from Honda drivers: “Tell me what to do, the original struts are expensive, but I installed Kayaba, and it hasn’t even lasted a summer!” The first question after the phrase “Kayaba, she’s such a Kayaba,” which in this case should be asked, “What kind of duster did you use?” As a rule, a person is either completely unaware of what the question is about, or, on the contrary, says, “yes, they sold a universal one in the kit, it tore within a week!” But it is in the boot that, in my opinion, 80% of the troubles of third-party racks for Honda lie. It's no secret that, in principle, KYB racks are not bad, I would even say quite decent, in terms of quality. It’s not for nothing that they are one of the world leaders in this production segment! But there is often dissatisfaction from Honda owners. And this doesn’t just apply to Kayaba. Companies such as Tokico, Monroe and others also get hit hard by angry car enthusiasts who installed struts from these manufacturers on their cars, and they failed in a short time. The problems of Honda drivers with struts are the following simple points:
Desire to save money in the segment where low price should be suspicious.
Wrong selection(or rather ignorance correct selection) racks according to the catalogue. For example, KYB stands for Honda Civic EU and Honda Stream are the same. But in reality, the original stands for Stream have a rod that is at least 1.5 times thicker! Accordingly, installing racks from the Civic on the Stream, seemingly correctly selected according to Kayaba, leads to their rapid failure.
The use of unknown anthers.
The third point, in my opinion, is the most important. An incorrectly selected (universal) boot, or a boot made correctly on the stand, but from poor material, quickly fails. As a result, the budget (see the first point on the list of problems!) Kayab (Tokikov) strut, which in principle should last at least 20,000 km, quickly fails, losing protection from water, dust and dirt, since the boot is already torn.
It’s not for nothing that it was mentioned about the budget - no one wants to take a GOOD stand, which is more expensive than the original, - everyone consoles themselves with the thought that for 5500 rubles a Kayaba will go like the original for 8000, and the “combat” Kayaba stand which is better than the original for 10,000 is generally it's a whim, isn't it?! 😉
Returning to the issue of anthers. It would seem that what the problem is - you can buy duplicate racks (the same kayaba) and put a separately purchased original boot on it! But that was not the case! Firstly, as was given in the example with the racks on the Stream and Civic, the original boot will not always fit on the “non-original” rack. Secondly, the original boot often costs half the price of a duplicate stand.
How to be? And, as usual, there are two ways out. The first one is “use original parts”, that is, “use original spare parts" Expensive? There is a second option - increase the frequency of “arrivals” to the service. If before this you visited a car service center twice a year to service your car, increase the number of “arrivals” to four or more. This will significantly increase the chance of “catching” a torn boot “at the start”, before the damage to the strut has reached critical levels. Of course, this will cost money, but do not forget about the “law of conservation of energy”; if something has arrived somewhere, then something has left somewhere. While you can’t beat this rule, if you managed to save on something, look for the moment where you will have to overpay for something. But in fact, everything is not scary, because as they say, “even if you are eaten, you have two options.” 🙂
