Most Renault Logan owners are interested in the process of replacing such low-resource chassis parts as the lateral stabilizer struts. Diagnosing a failed element does not provide for the need for special and expensive equipment, and replacing the stabilizer struts is very simple, as well as replacing the stabilizer rubber bands.
Lateral stability is important at the time of maneuvering in bends and on country roads, and the suspension that is present in the suspension design allows the car to be provided with this quality. Due to the perception of constant loads from lateral displacements, the struts are subject to wear. And then it is necessary to replace the rubber bands of the stabilizer and other parts. For the purpose of simplifying repair, the manufacturer has provided for the simplicity of the design of these elements, which can be safely called consumable.
About modifications
Some modifications of Renault Logan provide for the presence of a stabilizer in the rear suspension structure. Those owners of the model who have versions without rear stabilizers are given the opportunity to install them themselves.
The unpleasant moment here is the loss of warranty service for the Renault Logan car, which is in such a status. This factor keeps many owners from trying to interfere with their own hands (installing a stabilizer) into the factory structure.
Features chassis
The rear axle of Renault Logan does not provide for the presence of struts, since the structure is based on a continuous beam. Initially, this node is able to do without the presence of the elements in question. Vibrations in the vertical plane are very negligible, and the body is protected from lateral rolls by a horizontal bar fixed on the axis.
If you touch the front suspension, then there is a transverse stabilizer bar in its design. The manufacturer claims that the absence of this element is not capable of having a negative impact on reducing the level of safety in traffic. But practice shows: the presence of this part will not interfere with the confident behavior of the Renault Logan car.
How is it diagnosed?
It is rather difficult to independently diagnose a failed strut when replacement of stabilizer bushings or other element is required. The knock of its hinge is very similar to that made by a worn ball joint on the lever. If there are other negative sound effects, then you can suspect the Renault Logan steering rack in the wear of its elements.
A sufficiently effective search for the source of knocking will be the impact on each suspension hinge individually. To do this, we squeeze the rack with a pry bar and if this action succeeds, then we definitely resort to replacing the worn part, sometimes it is possible to replace the stabilizer bushings. The most reliable way to detect a faulty stabilizer post is to dismantle it, after which the worn hinge will produce play under the influence of manual force.
Replacement
The work involves the presence of a minimum of tools, because replacing the stabilizer struts is quite simple.
We stock up in advance:
- With open-end keys on: "10" and "13";
- Key "TORX T40";
- Head with size 18.
The procedure is performed according to the following algorithm.
- We hang out in front of Renault Logan by means of jacks. Do not forget about securing your car with stands. We recommend installing them under the subframe, which is especially important when dismantling not only the struts, but also the stabilizer bar itself.
- Before starting the "operation", we treat the threaded sections with a penetrating substance.
- Unscrew the nut from the stabilizer bar fixing bolt, then knock it out with a hammer.
- Next, unscrew the bolts that secure the rack itself directly.
- Until the strut is removed, "throw off" the brake hose from the bracket, which will ensure its safety during the designated work.
- The last step is to dismantle the rack mount bushings (they must also be replaced).
- Having dismantled both racks, we redirect our efforts to remove the rod. Here you should apply the technique of holding the nut using a Torx wrench of size 40. We unscrew it and then take out the bushing itself.
- Next, we move on to unscrewing the two bolts that secure the anti-roll bar to the surface of the subframe.
- Unscrew the nuts for fixing the staples. After these manipulations, the cushions with which the anti-roll bar is equipped are pry off with a suitable screwdriver and take out (can be taken to the side).
- It is recommended to install new analogues instead of dismantled pillows.
The assembly process is carried out according to the reverse algorithm. In this unit, it is desirable to replace the entire list of components, which will allow you to forget about the malfunction within a certain period.
Output
The material presented here shows the sequence of actions aimed at implementing the procedure for replacing the stabilizer struts in the Renault Logan model. It is not complicated, which once again confirms the practicality and constructive simplicity of this car.
Before installing the new Renault Logan anti-roll bar, it is recommended to find out how it works.
Purpose of the device
Experts refer to the functions of the unit:
- stabilization of the vehicle position on the road;
- reducing body roll when cornering;
- increasing the adhesion of wheels to asphalt;
- even load distribution.
Renault Logan stabilizer is presented in the form of a metal beam, each side of which is attached to the wheels of the axle. Experts distinguish between the front and rear racks on the Logan. To install them, bushings are used. The structure in question is fixed to the car body.
When replacing a device, its rigidity is taken into account. This parameter of the front stabilizer has a direct effect on the steering of the vehicle at the start of movement. Due to the increased rigidity, roll increases, traction on the front wheels, and the traction on the rear wheels decreases. A low stiffness value reduces lateral roll. To ensure greater reliability, completely eliminating the possibility of a rollover of the car, install a soft front stabilizer.
The device in question is a component of the Renault Logan suspension. The unit connects the wheels by means of a stop. For the manufacture of a large section and a U-shaped bar, spring steel is used. In the considered car brand, the stabilizer is located across the body. It is fixed with clamps. The stabilizer bushings provide rotation to the main structure. The device is fixed to the suspension by means of shock absorber struts or levers.
Front link: 1 - suspension subframe; 2 - suspension arm with silent blocks and ball joint; 3 - steering knuckle with hub and bearing; 4 - shock absorber rack; 5 - bar of the anti-roll bar.
If the bushing bursts, then suspension performance deteriorates. In this case, the vehicle is repaired. Auto mechanics recommend installing polyurethane Renault Logan stabilizer bushings and struts.
Unit replacement instructions
To replace the anti-roll bar, the chassis is disassembled. Replacing the stabilizer strut, bushings and the main unit is carried out using a jack, a set of keys, tie heads. Experts recommend replacing the stabilizer components in pairs (to ensure even wear).
Pre-dismantle the stabilizer protection. It is bolted on. Since the standard protection is made of plastic, it is recommended to replace it with a metal structure. To unscrew the earrings, use a standard ratchet. The new stabilizer is raised. The sleeves are inserted into the slots, fixing the earrings. The latter operation is performed with moderate force. The protective structure is installed in place.
To replace the anti-roll bar parts, use the keys to "10", "13", the socket head to "18", TORX T40. Pre-unscrew the nut of the stabilizer bar fixing bolt. In this case, it is necessary to keep the bolt from turning. Then dismantle the lower silent block. The rubber bush is dismantled. The next step is to remove the rod fixing bolt and turn out the rear subframe mounting bolt. If it is necessary to unscrew the 2 rear subframe mounting bolts, then the stops are pre-installed under the structure.
Then unscrew the nut fixing the bar bracket. To remove the rubber pad, you will need to pry it off with a screwdriver and pull off the bar mounting bracket. If the silent block and pillows are worn out or damaged, then they are replaced. New parts are purchased taking into account the VIN code and technical characteristics of Renault Logan.
Similarly, remove the 2 bolt for fixing the rod and the fastening bracket. Then dismantle the stabilizer bar. Parts are installed in reverse order.
Renault Logan anti-roll bar is a special design that has a U-shape and works in two modes - twisting and stretching. What are the features of such a detail? What functions does it perform? When 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 on a curve or when entering a bend, a group of centrifugal forces acts on the car body. 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, lateral roll appears, which leads to body swaying, impairs handling and reduces vehicle stability.
During the production process, the developers do their best to eliminate the processes described above. If you do not perform this work, the controllability of the machine deteriorates, and the tendency to overturn increases. The amount of roll and its level is largely dependent on the suspension travel. The larger it is, the higher the roll. To eliminate the problems mentioned, the following methods are applied:
- Installation of an additional unit that would play the role of an elastic element. In many cars (including Renault Logan), this function is performed by the anti-roll bar.
- Installing shock absorbers with a small stroke and limiting the movement of the levers. This option is usually used in sports cars.
Renault anti-roll bar takes over the following tasks:
- Leveling the car body during sharp maneuvers on the road.
- Reducing the level of roll that occurs when cornering.
- Redistribution of the load between the wheels.
- Improving the traction of the car with the road.
Structurally, the stabilizer has the form of a metal rod with a circular cross-section. Bushings and fixing clamps are used to fix the device to the body. The task of the bushings in the Renault anti-roll bar is to prevent the device from spinning while the vehicle is moving.
It is combined with the suspension elements of the stabilizer by means of shock absorber struts and special levers. The switching itself is performed using stabilizer racks
How does the device work?
The principle of operation 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 stability of the vehicle is ensured. At this stage, no less important are the bushings, which enable the device to twist in the middle.
- The resistance of the Renault stabilizer increases immediately after the roll increase. As a result, the body is leveled, additional stability is added. At the same time, the traction properties guarantee optimal tire grip during sharp turns.
How the SPU functions can be clearly seen in the video below.
The transverse stabilizer performs the assigned tasks the better, it has a more rigid structure. This indicator depends on a number of key factors:
- Linkage geometries.
- The shape of the knot in relation to the lower part of the car (bottom).
- The type of characteristics used in the production process, as well as its quality.
Installing a high-quality SPU on Renault guarantees stability when cornering, even when driving at high speed. At the same time, the driver practically does not feel the tilt of the body part to one side or the other. By adjusting the stiffness of the SPU, it is possible to adjust the stability and control parameter of the vehicle.
Pros and cons
The transverse stabilizer Renault Logan has its advantages and disadvantages. The pluses 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 travel of the independent suspension and "steals" a number of other useful qualities from it. For this reason, the device is installed on passenger cars, but rarely on SUVs. Such cars use a special stabilizer or they are not used at all.
How to replace the Renault Logan anti-roll bar?
Repair or replacement of the SPU on the 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.
It is possible to recognize a breakdown by the following signs:
- The car starts to pull left or right.
- Suspicious knocks 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 Renault Logan?
The SPU bushing plays a key role in ensuring the operability of the assembly as a whole. The appearance of a thud often indicates the destruction of the gum and the need to replace it.
"It is not worth tightening with the installation of a new bushing, because when this unit is destroyed, the ride comfort decreases and the stability of the car decreases"
If the bushing is serviceable, then longitudinal or transverse backlashes are excluded. In addition, the bar itself must be securely fixed by 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 finish them with WD-40. This makes it easier to tighten the nuts.
- 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 pipes of the fuel and brake systems (if necessary).
- Twist the stabilizer bush mounting stud and change the device.
How to change the bushings, you can watch the video:
Timely Renault repair and replacement of faulty components reduces the risk of deterioration in vehicle handling 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 the training video and get the job done.
Stabilizer struts - vehicle suspension parts. They are responsible for minimizing roll when the vehicle enters a corner. In all cars, the principle of the part is the same, the same applies to Renault Logan. Thanks to the Renault Logan stabilizer struts, the suspension and the body of the car are connected into one whole. If there were no stabilizers in the machine, then too much roll would be formed when entering a turn, and the car would roll over. When braking, the car would dive into the ground with the hood, and at a sharp start it would rears up.
The stabilizer struts are subject to significant stress, especially if the driver does not drive very carefully. The consequence of this operation of Renault Logan is to repair the stabilizer struts with your own hands or at a service station. Many people prefer to carry out this type of repair on their own, since it is cheaper and not difficult.
How does Renault Logan work and where is the anti-roll bar
The principle of operation of the anti-roll bar is focused on damping the translational waves that occur in various parts of the car on uneven roads when driving on them. Renault Logan stabilizer struts connect opposite wheels through a thrust element. The connection acts on twisting.
An anti-roll bar is installed on both the front and rear axles. This part is a large-section U-shaped bar and is made of spring steel. In Renault Logan, the stabilizer is located across and is secured with clamps and rubber bushings. Due to rubber bushings, the anti-roll bar is able to rotate. It is attached to the suspension with 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 bar
In poor road conditions, 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 sleeve may fray and burst. If this happens, the owner will feel it by the behavior of the car - he will noticeably shake on bumps, and the body will roll. When driving over speed bumps and other irregularities, the car may emit a knocking sound.Also, among the symptoms foreshadowing the need to replace the stabilizer struts - when driving, you need to catch a rut, constantly steer.
To get rid of all the unpleasant consequences of failure of the stabilizer bar, it must be repaired or a new one must be installed. Replacing the stabilizer struts Renault Logan does not involve any complicated actions. This work can be done independently, the whole procedure takes less than an hour.
Important! Failed stabilizer elements lead to breakage of other suspension parts. To avoid the need for more expensive repairs, the car should be periodically inspected for problems with the stabilizer bar.
How to replace the stabilizer bar Renault Logan
If the stabilizer bar is pulled laterally and a knock is heard, this indicates a malfunction. This problem can be solved by replacing the stand. But, some owners are thinking about how to repair the stabilizer struts with their own hands. Thus, they try to reduce the cost of fixing the problem. But, in some cases, it is still more reliable to make a replacement.
Did you know? Repairing stabilizer legs will significantly reduce costs. It is not difficult to carry out, but there are some peculiarities. It is easier to restore the bushings. With ball joints, the struts are rebuilt for a short period.
To replace the rack, you need tools such as a hammer, screwdriver, adjustable wrench, jack, TORX.
Renault Logan stabilizer strut replacement process:
- On the front wheel, loosen the nuts;
- Using a jack, raise the front part of the body, or if there is a lift, hang out the machine;
- The nuts are removed from the wheel, after which the wheel itself is removed;
- The stabilizer stand and the place of its attachment are cleaned of dirt;
- The item is processed with WD-40;
- Loosen the nut on the rack fixing bolt using TORX and at the same time tighten the flat head of the bolt with an adjustable wrench;
- Remove the nut and pillow. If the pillow is oxidized and considerable effort is required to remove it, the bolt can be gently knocked upwards with a hammer;
- When the pad is removed, the bolt itself can be knocked out with a hammer. Using a screwdriver, knock out the bolt that has entered the rack housing out of the housing;
- After removing the bolt, bend the stabilizer and remove the rack housing;
- Remove dirt from the mounting holes on the suspension arm and stabilizer;
- The new strut is installed between the suspension arm and the stabilizer;
- You need to put on the top pillow on the bolt and insert it into the rack body;
- A pillow and a fixing nut are installed below;
- Reassemble in reverse order.
Replacing the stabilizer bar bushings
A knock on bumps in the Renault Logan car is present due to worn out stabilizer bushings.This is the cause of lateral and longitudinal backlash. Therefore, it is required to replace the Renault Logan anti-roll bar bush.
Important! If a rubber squeak is heard on uneven road sections, check the stabilizer bushings. If you hear thuds, you need to check the racks.
Why change bushings
Bushings cause noise when worn. In general, this detail is very important, without bushings, metal breakage is likely during the movement of the machine due to overload. The bushings provide floating rotation of the stabilizer.
Do not wait until the bushings become completely unusable, it is recommended to replace them every 1000 km.
How to replace
To replace the rubber bands on the Renault Logan stabilizer, you need a 10 mm wrench and an 18 mm ratchet.
On the left side of the car:
The first step is to process the WD-40 mounting studs. This will make it easier to loosen 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 protection of the fuel and brake pipes. This will provide more room for unscrewing the stabilizer bush bracket stud. After all, we replace the bushing and assemble everything in the reverse order.
Renault Logan can be called a special car, but the systems in it do not differ from other cars. This also applies to the anti-roll bar. The sleeve does not fail so often, but if this happens, then the replacement is quite simple and even without outside help. Some motorists calculated the work time - it took no more than 40 minutes. But before carrying out the repair, it is worth figuring out what a stabilizer bar is.
The principle of the device
The anti-roll bar is a component of the vehicle's suspension. It connects opposite wheels by means of a thrust piece. The connection is twisting. The anti-roll bar is an integral part of passenger cars with independent suspension, including Renault Logan. It is installed on both the rear and front axles.
The element is a large U-shaped bar. It is made exclusively of spring steel. In Renault Logan, the stabilizer is located across and is fixed with clamps and rubber bushings. Due to the latter, the anti-roll bar rotates. It is attached to the suspension itself either with a shock absorber (used in a McPherson-type suspension) or with levers (in the common people - a multi-link).
The bushing can fray or even burst, and then the driver will feel the deterioration of the entire suspension - the car will shake noticeably on every bump, and the body will constantly heel. It is not difficult to solve the problem - the parts have several standard sizes, among which it is easy to choose the one suitable for your car. You can also purchase a replacement from an authorized Renault dealer, but we recommend getting something stronger. An excellent but more expensive option would be polyurethane.
Replacement instructions
We got acquainted with the device and the principle, now let's move on to the practical part. To replace, it is not necessary to completely disassemble the chassis. Lay a warm bedding, first placing the necessary tool next to it: keys of different sizes, screed heads and, of course, a new part, or better - two at once. It is recommended to change in pairs so that the wear goes evenly.
The first step is to remove the protective part of the stabilizer. Although this plastic cannot be called protection, we recommend installing a normal sheet of metal instead. The protection is fastened with ordinary bolts.
Now you need to unscrew the earrings. The easiest way to do this is with a standard ratchet. After unscrewing the earrings, the anti-roll bar goes down - now you can easily remove the old ones from it and replace it.
After replacing, lift the stabilizer up by hand, insert the bushings tightly into the sockets, and then fix them with earrings. And the last thing - we put the protection in place.
