Why is a stabilizer bar needed, what is its role?
Appearance of a used stabilizer link (wear is visible)
Anti-roll bar struts are the elements that directly connect the stabilizer itself to lower arm front suspension.
Details. Thus, the struts are not an independent unit, but are integral with the stabilizer and perform a common function - they prevent the occurrence of huge rolls when the car corners and diagonal swing.
- The design of the stabilizer link for Renault Logan is simple:
- A long bolt with a flat head and a short thread.
- Two pillows - lower and upper.
One-piece body.
Old and new stabilizer links (for comparison)
- Tasks of stabilizer struts
- Combating diagonal sway and roll in turns - preventing the car from tipping over.
- Stabilization in the horizontal plane of the car body. Ensuring acceptable adhesion road surface
- front wheels.
Maintaining balance when distributing loads.
Resource
When operating on bad roads and constant shock loads on the suspension, the struts will be considered a consumable item.
The average service life ranges from 15,000 to 20,000 kilometers.
At the same time, the stabilizer, which is a relatively powerful rod, is quite resistant to mechanical stress and lasts a long time.
Symptoms of a problem
- If the racks are very worn, then:
- When cornering, roll and diagonal sway increase - the body leans heavily to one side.
- When braking hard, the body sways.
- Increased susceptibility to rutting. The steering wheel requires course correction.
- Controllability deteriorates. Reactions on the steering wheel become less clear.
Reasons for part failure
- Driving on broken roads.
- Excessively active driving − high speed when taking turns and sharp maneuvers.
Diagnostics of stabilizer struts
In order to understand how worn the stabilizer link is, you need to stop by the station Maintenance in order to lift the car onto a lift and/or onto a viewing hole:
- The first step is to carry out visual inspection details. Finding it is quite simple - this is the connection at the end of the stabilizer, which attaches the latter to the suspension arm. After inspection, you need to manually determine the presence of play in the strut. If it is, then the element requires replacement.
- It is not always so easy to identify a faulty rack. There is another option - with the involvement of a partner. The procedure is carried out on inspection hole. The assistant should rock the car in a transverse plane, and the inspector should press his palm against the pillar and listen. If there is play or knocking, the part must be replaced.
Many people wonder: what to buy? original spare part or an alternative from a third party? Of course, products from the original catalog have a guarantee, but you can also buy “non-original” ones of quite high quality. Moreover, the price is much better.
Article number Lemforder 31243 01
Racks from Lemforder (catalog number Exist - 31243 01) can be considered a worthy alternative to factory ones (number in original catalog− 6001547138 or 8200277960).
Considering the condition of our roads, Logan drivers often choose polyurethane racks. The service life of such racks is longer and their reliability is better. But they also cost more!

Conclusion
The process of replacing a stabilizer bar on a Renault Logan is not very complicated. Therefore, every owner can perform the operation of this car. If, after installing a new part, the car still behaves “unassembled” on the road, then...
Stabilizer struts are car suspension parts. They are responsible for minimizing roll when the car enters a turn. In all cars, the principle of operation of the part is the same, the same applies to Renault Logan. Thanks to the Renault Logan stabilizer struts, the suspension and car body are connected into one. If there were no stabilizers in the car, then when entering a turn there would be too much roll and the car would roll over. When braking, the car would dive with its hood into the ground, and with a sharp start it would rear up.
The stabilizer struts bear a significant load, especially if the driver does not drive very carefully. The consequence of such operation of the Renault Logan is the repair of the stabilizer struts with your own hands or at a service station. Many people prefer to do this type of repair themselves, as it is cheaper and not difficult.
How does it work and where is the Renault Logan anti-roll bar located?
The principle of operation of the anti-roll bar is focused on damping forward waves that arise in various parts of the car on uneven roads when driving on them.
Renault Logan stabilizer struts connect opposite wheels via a thrust element. The connection acts on torsion. A stabilizer bar is installed on both the front and rear. rear axle This item It is a U-shaped rod with a large cross-section, and is made from spring steel. In Renault Logan, the stabilizer is located across and secured with clamps and rubber bushings
. Due to the rubber bushings, the anti-roll bar is able to rotate. It is attached to the suspension by levers or a shock absorber strut. Did you know?
After replacing the stabilizer struts, there is no need to adjust the wheel alignment. The racks do not affect their angle of inclination in any way.
Reasons for replacing the stabilizer link Under operating conditions at bad roads The load on the suspension is significant, and the struts become a consumable part. Their service life is within 15-20 thousand kilometers. During operation, the bushing may fray or burst. If this happens, the owner will feel it from the behavior of the car - it will shake noticeably on uneven surfaces, and the body will roll. When hitting speed bumps or other bumps, the car may make a knocking sound.
Also among the symptoms that foreshadow the need to replace stabilizer struts is that when driving you need to catch a rut and constantly steer. unpleasant consequences If the stabilizer link fails, it must be repaired or a new one installed. Replacing Renault Logan stabilizer struts does not involve any complicated steps. You can do this work yourself; the whole procedure takes less than an hour.
Important! Failure of stabilizer elements leads to failure of other suspension parts. To avoid the need for more expensive repairs, the car should be periodically inspected for problems with the stabilizer link.
How to replace a Renault Logan stabilizer link
If the stabilizer bar is pulled in the transverse direction and a knock is heard, this indicates a malfunction. This problem can be solved by replacing the stand. But, some owners are wondering how to repair stabilizer struts with their own hands. Thus, they try to make it cheaper to fix the problem. But, in some cases, it is still safer to make a replacement.
Did you know? Repairing the stabilizer mounts will significantly reduce costs. It is not difficult to perform, but there are some peculiarities. It is easier to restore racks with bushings. With ball joints, the struts are restored for a short period.
To replace the strut, you need tools such as a hammer, screwdriver, adjustable wrench, jack, TORX.
The process of replacing the Renault Logan stabilizer link:
- On the front wheel, you need to loosen the nuts;
- Using a jack, raise the front part of the body, or, if there is a lift, hang the car;
- The nuts are removed from the wheel, after which the wheel itself is removed;
- The stabilizer strut and its attachment point are cleaned of dirt;
- The part is treated with WD-40;
- On the post fixing bolt, loosen the nut using TORX and at the same time tighten the flat head of the bolt with an adjustable wrench;
- Remove the nut and cushion. If the cushion has oxidized and considerable effort is required to remove it, the bolt can be carefully knocked out with a hammer;
- When the cushion is removed, you can use a hammer to knock out the bolt itself. Use a screwdriver to knock out the bolt that has entered the rack housing out of the housing;
- After removing the bolt, bend the stabilizer and remove the strut housing;
- Clean the mounting holes on the suspension arm and stabilizer from dirt;
- A new strut is installed between the suspension arm and the stabilizer;
- You need to put the top pad on the bolt and insert it into the rack body;
- A cushion and a fixation nut are installed at the bottom;
- Reassemble in reverse order.
Replacing stabilizer link bushings
A knock on bumps in a Renault Logan car is present due to worn stabilizer bushings. This is the reason for the appearance of transverse and longitudinal play. Therefore, it is necessary to replace the Renault Logan anti-roll bar bushing.
Important! If you hear a rubber squeak on uneven sections of the road, you need to check the stabilizer bushings. If you hear dull knocks, you need to check the racks.
Why change bushings?
When the bushings wear out they cause noise. In general, this part is very important; without bushings, the metal is likely to rupture while the machine is moving due to overload. Thanks to the bushings, floating rotation of the stabilizer is ensured.
You should not wait until the bushings become completely unusable; it is recommended to change them every 1000 km.
How to make a replacement
To replace the rubber bands on the Renault Logan stabilizer, you will need a 10 mm wrench and an 18 mm ratchet.
On the left side of the car:
The first step is to treat the mounting studs with WD-40. This will make it easier to remove the nuts and bolts. After removing them, you need to remove the bushing bracket and replace it with a new one.
On the right side of the car:
Remove the muffler rubber bands, partially unscrew the fuel and brake pipes. This will provide more room to unscrew the stabilizer bushing bracket stud. After everything, we replace the bushing and reassemble everything in the reverse order.
The Renault Logan anti-roll bar is a special design that has a U-shape and operates in two modes - torsion and tension. What are the features of such a detail? What functions does it perform? In what cases is it necessary to replace the anti-roll bar? Consider these and other questions below.
Purpose and design features of SPU Renault Logan
When driving along a curve or when entering a turn, a group acts on the car body centrifugal forces. The emerging loads are evenly distributed between the various elements of the car. In this case, part of the load is removed from the inner wheels and transferred to the outer wheels. As a result, it appears lateral roll which causes the body to sway, impairs handling and reduces stability vehicle.
During the production process, developers do everything possible to eliminate the processes described above. If you do not do this work, the controllability of the machine deteriorates and the tendency to rollover increases. The amount of roll and its level largely depend on the suspension travel. The larger it is, the higher the roll. To eliminate these problems, the following methods are used:
- Installation of an additional node that would play a role elastic element. In many cars (including Renault Logan), this function is performed by an anti-roll bar.
- Installation of shock absorbers with a small stroke and restriction in the movement of levers. This option is usually used on sports cars.
The Renault anti-roll bar undertakes the following tasks:
- Alignment of the car body during sudden maneuvers on the road.
- Reducing the level of roll that occurs when turning.
- Redistribution of load between wheels.
- Improving the quality of the car's grip on the road.
Structurally, the stabilizer has the form of a metal rod with a circular cross-section. To fix the device to the body, bushings and fastening clamps are used. The task of the bushings in the Renault anti-roll bar is to prevent the device from rotating while the car is moving.
It is combined with the stabilizer suspension elements using shock absorber struts and special levers. The switching itself is carried out using stabilizer struts
How does the device work?
The operating principle of the Renault anti-roll bar is as follows:
- In the presence of angular vibrations, as well as when tilting to the left or right side The stabilizer links also move. As a result, the vehicle's stability is ensured. At this stage, no less important are the bushings, which allow the device to twist in the middle.
- The resistance of the Renault stabilizer increases immediately after the roll increases. As a result, the body is leveled, adding additional stability. At the same time, the traction bars guarantee optimal tire grip during sharp turns.
How the SPU functions can be clearly seen in the video below.
Transverse stabilizer performs the assigned tasks the better, the more rigid the structure it has. This indicator depends on a number of key factors:
- Geometry of traction fixation.
- The shape of the unit is relative to the bottom of the car (bottom).
- The type of characteristics used in the production process, as well as its quality.
Installing a high-quality SPU on a Renault guarantees cornering stability even when driving high speed. In this case, the driver practically does not feel the body part tilting to one side or the other. By adjusting the rigidity of the control system, it is possible to adjust the stability and controllability of the vehicle.
Advantages and disadvantages
The Renault Logan transverse stabilizer has its advantages and disadvantages. The advantages include:
- Improved handling.
- Reduced roll during sharp turns.
- Reliability and long service life.
On the other hand, the stabilizer also has a number of disadvantages. In particular, it reduces the stroke independent suspension and “steals” a number of other useful qualities from her. For this reason, the device is installed on passenger cars, and is rarely mounted on SUVs. In such cars, a special stabilizer is used or they are not used at all.
How to replace a Renault Logan anti-roll bar?
Repair or replacement of SPU on Logan is carried out in a situation where obvious deformation was noticeable during the inspection. In addition, the device must be repaired (replaced) if the elasticity of the sleeve deteriorates. In the latter case, the element requires replacement.
A breakdown can be recognized by the following signs:
- The car starts to pull to the left or right.
- Suspicious knocking sounds appear in the front suspension.
- Inspection showed the presence of deformation of the product.
The device is replaced according to the following algorithm:

How to change stabilizer bushings on a Renault Logan?
The SPU bushing plays a key role in ensuring the performance of the unit as a whole. The appearance of a dull knock often indicates the destruction of the rubber band and the need to replace it.
“You shouldn’t delay installing a new bushing, because if this unit is destroyed, the ride comfort decreases and the car’s stability decreases.”
If the bushing is in good condition, then longitudinal or transverse play is excluded. In addition, the bar itself must be securely fixed by the devices and not rotate in its axis.
To change the bushings yourself, proceed as follows:
- Prepare a key for “ten” and a head for “eighteen”.
- On the left, clean the mounting studs and treat them with WD-40. This makes the process of tightening the nuts easier.
- Unscrew the nut by “ten”, and then the bolt by “eighteen”.
- Remove the bushing bracket and replace the device.
- On the right, remove the rubber bands from the muffler, the protection of the fuel and brake system(if required).
- Unscrew the stud securing the stabilizer bushing and change the device.
You can watch the video on how to change bushings:
Timely repairs Renault and replacement faulty elements reduces the risk of deterioration in vehicle controllability and stability. The main thing is to diagnose the problem in a timely manner and act competently in the process of troubleshooting. If difficulties arise, you can always watch a training video and do the work.
