Renault Logan rear shock absorbers, under certain conditions, may be subject to greater loads than the front struts. So that once again, when returning from the dacha with a trunk full of potatoes, or when transporting several bags of cement in a car for home repairs, you do not encounter the problem of failure of these parts, you must take care in advance of installing high-quality struts on the rear axle of the Renault Logan car. This article will discuss in detail not only the issue of choosing products, but also their correct installation. In addition, every Renault Logan owner needs to know how to recognize the signs of a malfunction in time.
When is it necessary to replace shock absorbers on a Renault Logan?
Some suspension malfunctions can mislead the driver as to the true cause of the shock absorption system problems. In order not to make a “false positive diagnosis” and not to perform a large number of repair work in vain, it is necessary to clearly understand what signs may clearly indicate a rack failure.
Signs of wear and problems
Any noise from the suspension elements should alert the driver. A properly operating car should produce only characteristic sounds that appear from tire friction on the road and fuel detonation in the cylinders. If other “soloists” appear against this background, then it is urgent to find out the cause of the appearance of extraneous noise. The sooner the inspection is done, the less expensive it will be to repair the car. In addition, operating a vehicle with this type of malfunction can lead to serious accidents on the road.
If the driver does not hear any sound changes in the operation of the car, but feels vibration with his whole body while driving, then most likely the shock absorber is stuck. In most cases, such damage cannot be repaired, so to restore the functionality of the suspension, you will need to install new struts.
Attention! A hydraulic fluid leak from the shock absorber is a sure sign that the struts will need to be replaced in the near future.
What signs indicate problems with the support bearing?
According to the regulations established by the manufacturer, there is no exact date for replacing the bearing. Its service life directly depends on the use of the car. So, under certain conditions, a bearing may become unusable after 60 thousand kilometers, or maybe even after 120 thousand.
The element must be replaced immediately after signs indicating its wear appear. It is important not to miss this moment, as it is extremely important for maintaining the steering of the car and the correct geometry of the front suspension.
There are several signs that indicate support bearing wear:
- Loss of free play of the steering wheel.
- Creaking and knocking noises in the A-pillar area when driving over uneven surfaces.
- Knock when turning the steering wheel.
- Vibrations transmitted to the steering rack and steering wheel (drivers characterize this symptom with the expression “the steering wheel hits”).
- Unstable operation of the steering (the car pulls to the side or left and right).
- The front shock absorber strut rod is located significantly higher than the level of the spar support cup.
If such signs appear, driving is prohibited. At best, the shock absorber strut and steering rack may become unusable; at worst, the car will behave unpredictably and in the event of a critical situation the driver may not be able to control it.
Diagnostic methods
You can diagnose the rear shock absorbers of a Renault Logan phase 2 yourself in a garage or on a parking lot. For this purpose, it is enough to rock the car from the side of the wheel whose shock absorber strut may be faulty. If, after the mechanical impact on the car has ceased, the body continues to make vertical movements for some time, then this “behavior” of the suspension will indicate a malfunction of the part.
In this way, you can check all the car’s shock absorbers one by one, including the front ones.

Which front and rear shock absorbers are better to install?
When choosing new shock absorbers, it is better to proceed from what shock absorbers should not be installed on the car. This category of parts includes:
- Used.
- Counterfeit products.
- Shock absorbers on which traces of external mechanical influence are visible to the naked eye.
- Parts from other cars that are not complete analogues (the suspension elements need to be modified).
If you ignore the above points, then a short time after the completion of the repair and a short period of operation, you will need to disassemble and repair the Renault Logan shock absorbers again.
How to identify faulty shock absorber struts: watch the car
To diagnose the condition of the shock absorber struts, it is not necessary to go to a service station for help or completely disassemble the suspension system - the failure of parts can be determined by the behavior of the car on the road. Characteristic signs requiring immediate repair are:
- Difficult maneuvering or strong roll when cornering;
- The presence of extraneous sounds, knocks or impacts in the wheel area while overcoming obstacles;
- Strong vibration loading of the steering wheel or swaying of the car body when reaching cruising speed;
- The presence of oil leaks after a long period of parking under the wheels of the car;
- Problems are observed during emergency braking or an increase in braking distance is noticed;
- On tires with correct camber, uneven tread wear is monitored.
If one or more signs are present on the vehicle, it is recommended to inspect the suspension as a whole - if the car easily swings on the racks or there are deformed parts in the structure, it is recommended to urgently repair or replace components.
It is important to know! If a shock absorber strut fails, in most cases it becomes impossible to operate the car until the cause of the breakdown is completely eliminated, while with a deformed spring it is still possible to continue driving to the nearest service station.
Types of shock absorbers that can be installed
Before replacing Renault Logan shock absorbers, it is necessary to carefully approach the issue of selecting the type of struts. For this purpose the following can be used:
- Oil shock absorbers.
- Gas-oil shock absorbers.
Which type of parts to choose depends on driving style and operating conditions. Oil products are softer, so they are ideal for measured driving around the city or at medium speeds on the highway. Gas-oil struts are more expensive, rigid and are suitable mainly for a sporty driving style.
Characteristics and articles of factory shock absorbers
If the task is not to make a sports car out of an ordinary sedan, then you can limit yourself to installing stock models of shock absorber struts on the car. In order not to drown in a sea of similar products, product coding acts as a kind of beacon.
Attention! By selecting a part according to the article number, you can be sure that you will be purchasing an original shock absorber strut.
The factory front suspension elements of this type have the following code designations:
- 543020322R - very soft products, ideal for use within the city.
- 543024260R – Renault Logan front shock absorber. Product of medium hardness.
- 543022905R – very rigid struts, ideal for a sporty driving style.
Article numbers for rear factory struts for Renault Logan:
- 543025333R - the softest shock absorber struts.
- 543021712R – products of medium hardness.
- 543020952R – rigid shock absorber struts designed for a sporty driving style.
Attention! When selecting a product by article number, you must be very careful. An error of even one character can make it impossible to change the suspension elements of a particular car model.
High-quality analogues and their cost
Original shock absorbers are easy to find and purchase, but installing such products is not always the best solution.
There are a sufficient number of analogues on the market that can surpass factory products in quality and are much cheaper in cost. This category of spare parts for Renault Logan includes:
- Kayaba - KYB338759. Twin-tube front shock absorber.
- Asam – 32703. Front shock absorber with increased rigidity.
- HOLA – 338713. Front shock absorber struts, which are ideal for installation on Renault Logan 2007 – 2010 model years.
- BILSTEIN – 19122472. Gas shock absorber for rear suspension.
- FENOX – A220004. Rear pillar of Renault Logan.
Each of the listed racks can be installed on Renault Logan without any modifications (they are complete analogues).
How to install inserts
To increase rigidity and increase ground clearance, many car owners prefer to install spring inserts on Renault Logan, which will prevent the car from sagging on the roads. They are made of dense material that can withstand increased loads. There are several types of spacers for springs:
Options for using shock absorbers from the first generation Logan
If spare parts for the first generation of a car of this model were purchased by mistake for installation on a Renault Logan, then this fact is not an obstacle to performing high-quality car suspension repairs.
In this case, the part is installed in the standard way, with the only difference being that the length of the first generation Renault shock absorber rod will be slightly longer. This suspension conversion is not very suitable for a sporty driving style. The shock absorption system will be much softer than with the original struts, so after repair the car can be used in standard driving mode.
Removing the shock absorber
Signs that the shock absorber needs to be removed:
- loss of performance;
- presence of deformation;
- significant abrasion of the silent block;
- damage to rubber cushions;
- failure of the cover or compression stroke buffer.
Open the trunk, remove the trim on the wheel arch.
Unscrew the shock absorber fasteners at the top using the “No.16” key. Do not allow the rod to rotate; to do this, hold it with the “No.6” key.
Remove the support washer and the rod mounting pad at the top.
Unscrew the shock absorber fastener to the lever from the bottom using the “No.18” key.
- We dismantle the shock absorber system and pillows from below. The bushing, support washer, power buffer and protection cover are also assembled.
- Elements that need to be replaced are replaced with new ones.
- On the eve of installing the shock absorber in place, assemble the entire system.
- We install the node in the reverse order of this one.
Do-it-yourself replacement of Renault Logan rear shock absorbers
You can install new shock absorbers on Renault Logan yourself. This procedure will not take much time, but only on condition that the entire process is carried out strictly according to the instructions. In addition, it is recommended to simultaneously change parts located on the same axis.
For example, if the left shock absorber is faulty, then the right one should also be installed.
Removing the shock absorber strut
The first thing you need to do when repairing the Renault Logan rear suspension is to remove the shock absorber strut. For this operation you need:
- Open the trunk.
- Remove the side trim on both sides.
- Secure the rod with a special key, and use another to unscrew the nut holding this part.
- Remove the washer and shock absorber cushion.
- Using a jack, lift the wheel on the side from which the part is being removed.
- Unscrew and remove the lower shock absorber strut bolt.
- Remove the defective part.
After removing the stand, it must be cleaned of dirt and dust.
Disassembling the rack
To disassemble the rack, you cannot do without special spring ties. This tool should be installed opposite each other. Then you need to tighten the spring evenly using this device.
Attention! A compressed spring has a large potential reserve of energy, which, when released, can have a destructive effect on objects and the human body.
When the spring is compressed, it is necessary to unscrew the fastening nut and the upper support bearing. Then carefully remove the spring.
Assembly diagram
Before replacing the rear stock shock absorber, it must be bled manually to develop a new valve. Then you need to put a spring on it, install a support bearing, install a washer and nut on the rod. Then you should evenly loosen the compression of the spring with ties and remove the devices from the coils.
When the assembly of the shock absorber strut is completed, it is installed on the car in the reverse order of removal. At the same time, a good result of fixing the part can be achieved during the final tightening of the threaded connections, when the car is installed on the wheels.
Replacing front struts
To replace the front strut of this car, it is necessary to disassemble the unit connecting it to the body, more precisely, the upper support, the so-called. cup, and also disassemble the “shock absorber body – steering knuckle” connection. We will need a set of the following tools:
- hexagon 6;
- curved spanners 21 and 27;
- spanner 13;
- open-end wrench 17.
The preparatory stage of work begins with securing the car with a handbrake and wheel chocks, continues with jacking up one side of the car and ends with removing the front wheel.
Front pillar
Before replacing this unit, it is necessary to remove dirt from the front suspension elements located in the wheel arch. Start cleaning the hardware that secures the shock absorber body to the steering knuckle in order to treat them with penetrating liquid and make disassembly easier.
Replacing the front suspension struts of this machine is carried out in stages:
- Since the shock absorber strut is attached to the car body (cup) and is called the top mount, the nut of this assembly must be loosened. This is done using a 21-point bent spanner to unscrew the nut, and a 6-point hex to keep the rod from rotating.
- The lower mount connects the strut and the steering knuckle. To disassemble it, you need to loosen the nuts of the bolted connection. To remove the lower mounting bolt of this assembly, the floating brake caliper is displaced, since without this it is impossible to remove the bolt. To do this, you need a 13mm wrench to unscrew the mounting bolt and release the upper pin, which is held in place by a 17mm wrench.
- The bracket is moved away by rotating along the lower finger. To unscrew the fastening bolts and nuts on the shock absorber body to the steering knuckle, you need ring wrenches, which can be replaced with 18-mm heads. Now nothing prevents the upper bolt from leaving the hole. In the same way, you can unscrew the nut and remove the bolt from the bottom from the hole.
- You need to completely unscrew the nut on top of the shock absorber mounting and remove the strut. The steering knuckle is secured with a wire inside the wheel arch (suspended from the brake hose bracket or other protruding element to prevent tension in the caliper brake tube).
- All that remains is to replace the removed rack with a new one or disassemble it and install factory spare parts. Finally you need to reassemble.
Shock absorbers are always replaced only in pairs, so as not to worsen the car's handling.
How to change RenaultLogan front shock absorbers
The process of replacing front shock absorbers is no more difficult than repairing the rear suspension, but one should take into account the fact that when performing such work, the toe-in and camber angles of the front wheels may be disrupted.
The step-by-step process for installing new racks may look like this:
- Open the hood and remove the nut located above the support bearing.
- Remove the upper support bearing cup.
- Remove the wheel from the side where you plan to replace the strut.
- Jack up the car.
- Remove the bolts holding the strut to the steering knuckle.
- Remove the shock absorber assembly.
If the new part is supplied with a spring, then you can begin assembling the unit in the reverse order of removal. Otherwise, you need to disassemble the stand as described above.
What kind of malfunctions are there?
To understand what kind of support bearing malfunctions occur and check their condition, you need to open the hood, lean hard on the thrust cup of the spar and rock the car up and down for a few seconds. If knocking or play occurs, the bearing must be replaced.
In addition, you can ask an assistant to intensively rotate the steering wheel and at this time check the movement of the bearing. If the rack is displaced or play is noticed, then replacement is inevitable.
The position of the shock absorber strut rod may also be an indicator of a mechanism malfunction. If it is in good condition, it will not protrude beyond the edge of the cup. On Logan, such an element as the support bearing cannot be restored; the only way out is to replace it.
