Bar of the stabilizer of cross stability logan. Anti-roll bar Renault Logan

While driving, the car, passing a sharp turn, begins to lean to the side. Tilt degree vehicle depends on two factors. This is the centrifugal force trying to push the car off the road and the elasticity of the car's suspension, which is aimed at keeping the car on the road.

Properly distributed force between the left and right suspension will reduce the angle of inclination of the car when entering a turn. Structural element, which is entrusted with these functions, is an anti-roll bar that connects the left and right suspension of the car.

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

The elements are connected through the stabilizer struts, which are not independent nodes, but work in tandem with the transverse stabilizer. Their joint action is aimed at:

• reduction of diagonal buildup;
• prevention of car rollover;
• the return of the car to the horizontal plane during sharp turns;
• maintaining grip with the road surface;
• balanced load distribution.

During operation, constant loads lead to wear of the rack. To simplify car repairs, the manufacturer made the part the simplest in design, which classifies the spare part as consumables.

The stabilizer bar of the 2nd generation Logan car itself consists of three structural elements:

• Bolt with short thread and cap.
• Top and bottom cushions.
• Frame.

With careful operation of the car, the stabilizer struts will regularly serve all 20 thousand kilometers. If the machine has been used for poor coverage with potholes and pits, then the part will have to be changed much earlier. How to understand how worn the stabilizer assembly is?

Main signs of wear:

• when turning the car begins to lean strongly to one side
• when driving on a rough road, a distinct metallic knock is heard
• at the moment of a sharp stop of the car, the car sways and can demolish the transport in one side
• decrease in vehicle controllability, sometimes you have to return the car to its previous course by turning the steering column.

The reasons for the appearance of violations in the work of Renault Logan may be careless driving on a broken pavement, as well as aggressive driving and abrupt maneuvers. And then the question arises about the condition of the node and the need to replace the stabilizer strut.

To resolve this issue, the following steps need to be taken:

• The car is driven onto a lift, for this you need to go to the service station or put it on a viewing hole.
• Spend visual inspection node. The stand is located at the end transverse stabilizer. Try to loosen the suspension. If play is detected, then the part needs to be replaced.
• You can't always do it alone. Having previously placed the car in the pit, it is necessary that someone else shake it in the transverse direction. Being under the car, carefully observe the movement yourself, lean your hand against the suspension, and listening, try to catch a knock inside the mechanism. The presence of play and a characteristic knock will mean that a replacement part is needed.

At this stage, a new difficulty arises with the choice of a quality part. Of course, it is best to purchase and install the original sample. But it can be much more expensive than an analogue from another manufacturer, which is no different from the branded one in terms of build quality. So which ones are better? Non-genuine parts do not have the same markings, they may differ from original material quality and chemical composition, but at the same time, they are delivered to the buyer as original spare parts of excellent quality.

Modern technologies make it possible to make the part very similar to the original. A few tips when choosing original spare parts:

• almost all the parts from which the car is assembled have their own individual number. We may not know him and never meet him. Car manufacturers have databases for each model with the numbers of used car structural elements and this data can be found on specialized resources in the Internet;
• package original spare part must be accompanied by the manufacturer's logo, documentation or installation instructions;
• the original product must have an inscription, label or brand.

Polyurethane racks also serve as an alternative to factory products, they are stronger, more reliable, but their cost also differs from steel ones in a big way.

As a result, the car rides much quieter, handling on the track with high speeds It gets better. In urban conditions, there are no differences, but the speed on turns is clearly less here.

What threatens a faulty rack

In the event of a malfunction in the control, the vehicle should be immediately repaired. Loss of vehicle stability can have serious consequences. The car can get into an accident or provoke a traffic accident. An uncontrolled car carries unpredictable consequences. Even the slightest knock in the mechanism of the car distracts the driver's attention from the road.

The slightest wear or microcrack progresses over time and can develop into a major defect, resulting in third-party noise and significant body roll when driving. It is not necessary to drive the car to a car repair shop, you can replace the rack yourself.

How to replace the stabilizer bar

First you need to prepare the tool:

• hammer;
• wrench;
• Screwdriver Set;
• jack;
• end nozzle TORX t45 for 10.

Do-it-yourself rack replacement steps:

• Loosen wheel nuts.
• Raise the car with a jack.

• Unscrew the nuts and dismantle the wheel.

• Clean the place of fixation of the stabilizer strut from dirt.
• The mount is processed with a universal tool WD-40.
• After a while, you should try to loosen the strut bolt nut with the end cap. In this case, it is better to hold the bolt head with an adjustable wrench.
• Next, the nut itself is removed along with the pillow.

• If it is difficult to release the pillow, you can use a hammer and try to knock out the bolt.

• Upon completion of the dismantling of the bolt, the stabilizer bends to the side and the rack assembly is removed.

• The installation site of the stabilizer is thoroughly cleaned of dirt.
• Now you can put new part. A pillow is put on the bolt and installed in the rack housing.
• A sealing pad is also put on from the bottom of the rack and the nut is tightened.

• On this, the process of replacing the stabilizer strut can be considered complete.

Advice. After assembling the assembly, it is necessary to check the result of the work and drive a car. If it also behaves as it did before the repair, then you need to look for problems in other systems and nodes or contact a car service.

Replace a failed stand Renault Logan quite easy. The car owner can complete all the steps on his own, adhering to detailed instructions on videos and photos provided by specialized automotive sites.

Renault Logan can be called special car, but the systems in it are no different from other machines. This also applies to the anti-roll bar. The bushing does not fail so often, but if this happens, then the replacement is quite simple and even without outside help. Some motorists calculated the time of work - it turned out no more than 40 minutes. But before carrying out repairs, it is worth understanding what a stabilizer bar is.

Device principle

The anti-roll bar is a suspension component of the machine. It connects opposite wheels by means of a thrust element. The connection is torsion. Anti-roll bar - an integral part 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 from 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 by a shock absorber strut (used in a McPherson-type suspension) or by 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 noticeably shake on every bump, and the body will constantly roll. It is not difficult to solve the problem - the details have several regular sizes among which it is easy to choose the right one for your car. You can also purchase a replacement from official dealer Reno, but we recommend taking something stronger. Great but more an expensive option become 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, after laying next to essential tool: keys different sizes, coupler heads and, of course, a new part, or better, two at once. It is recommended to change in pairs so that wear occurs 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 fixed 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, raise the stabilizer with your hand up, insert the bushings tightly into the sockets, and then fix them with earrings. And the last - put the protection in place.

To complete the work, you will need a car stand, a jack and wheel chocks.

1. We prepare the car for work and hang out the front wheels.

2. Shoot front wheel(see).
3. Holding the screw from turning with a TORX T40 wrench ....

Using a 13 mm socket wrench, unscrew the nut securing the stabilizer strut.

The anti-roll bar nut is self-locking and cannot be reused, so it must be replaced during assembly.

4. Remove the washer and bottom cushion.

5. Remove the screw.

6. Remove the washer and top cushion.

7. Remove the rubber bushing of the rack.

8. We replace worn and damaged rack parts.
9. Install the stabilizer bar in reverse order. Tighten the rack mounting nut with a torque of 20 Nm.
10. Similarly, we replace the second strut of the anti-roll bar.

Anti Roll Cushion

To perform the work, an inspection ditch or overpass is required.

1. We install the car on a viewing ditch or overpass and prepare it for work.
2. We process the stabilizer bar mounts with a penetrating lubricant.

3. Using a 10 mm wrench, unscrew the nut securing the stabilizer bracket.

Anti-roll bar Renault Logan - a special design that has a U-shape and operates in two modes - twisting and stretching. 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 of 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 internal and transferred to the external wheels. As a result, a transverse roll appears, which leads to body sway, impairs handling and reduces vehicle stability.

During the production process, developers do their best to eliminate the processes described above. If this work is not done, the controllability of the machine deteriorates, and the tendency to overturn increases. The amount of roll and its level largely depend on the suspension travel. The larger it is, the higher the roll. To eliminate the mentioned problems, the following methods are used:

• Installing 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.

• Installing shock absorbers with a small stroke and limiting the movement of the levers. This option is usually used on sports cars.

The Renault anti-roll bar performs the following tasks:

• Alignment of the car body during sharp maneuvers on the road.
• Reducing the level of roll that occurs when cornering.
• Redistributing the load between the wheels.
• Improving the quality of the grip of the car with the road.

Structurally, the stabilizer has the form of a metal rod having a circular cross section. Bushings and mounting 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 scrolling while the car is moving.

It is combined with stabilizer suspension elements using shock absorber struts and special levers. The switching itself is carried out 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 tilted to the left or right side The stabilizer links also move. As a result, the stability of the car is ensured. At this stage, bushings are no less important, which allow the device to twist in the middle.
• Renault's stabilizer resistance increases immediately after the bank rises. As a result, the body is leveled, added additional stability. At the same time, the traction bars guarantee optimal tire grip on the track during sharp turns.

How the SPU functions can be clearly seen in the video below.

The transverse stabilizer performs its tasks the better, it has a more rigid design. This indicator depends on a number of key factors:

• Traction locking geometries.
• Knot shapes regarding the bottom of the car (bottom).
• The type of characteristics used in the production process, as well as its quality.

The installation of high-quality SPU on Renault guarantees cornering stability even when driving on high speed. At the same time, the driver practically does not feel the inclination of the body part to one side or the other. By adjusting the rigidity of the SPU, it is possible to correct the stability and controllability of the vehicle.

Advantages and disadvantages

The Renault Logan transverse stabilizer has its advantages and disadvantages. The pluses include:

• Manageability improvement.
• Reduce roll during sharp turns.
• Reliability and long service life.

On the other hand, the stabilizer has a number of disadvantages. In particular, it reduces the stroke independent suspension and “steals” from her a number of other useful qualities. For this reason, the device is installed on cars, and rarely mounted on SUVs. In such cars, a special stabilizer is used or they are not used at all.

How to replace the anti-roll bar Renault Logan?

Repair or replacement of SPU on Logan is carried out in a situation where obvious deformation was noticeable during the inspection process. In addition, the device is subject to repair (replacement) if the elasticity of the sleeve deteriorates. In the latter case, the element needs to be replaced.

Damage can be recognized by the following signs:

• The car starts to pull to the left or right.
• There are suspicious knocks 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?

SPU sleeve plays key role in ensuring the operability of the node as a whole. The appearance of a thud often indicates the destruction of the gum and the need to replace it.

"Tighten with the installation new bushing it’s not worth it, because if this node is destroyed, the comfort of the trip decreases and the stability of the car decreases”

If the sleeve is serviceable, then longitudinal or transverse backlashes are excluded. In addition, the bar itself must be securely fixed by devices and not scroll in its axis.

To change the bushings yourself, proceed as follows:

• Prepare the key for "ten" and the head for "eighteen".
• On the left, clean the mounting studs and treat them with WD-40. This facilitates the process of twisting the nuts.
• Unscrew the nut to "ten", and then - the bolt to "eighteen".
• Dismantle the bushing bracket and change the device.
• On the right, dismantle the rubber bands from the muffler, the protection of the fuel and brake system(if required).
• Twist the stabilizer bushing stud and change the device.

How to change the bushings, you can watch the video:

Timely repair Renault and the replacement of defective elements 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 there are difficulties, you can always watch the training video and do the work.

Most Renault Logan owners are interested in the process of replacing such low-resource chassis parts as the transverse 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 corners and on suburban highways, and the suspension present in the design allows you to provide the car with this quality. Due to the perception of constant loads from transverse displacements, the racks 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 repairs, the manufacturer has provided for the simplicity of the design of these elements, which can be safely called consumables.

About modifications

Some modifications of Renault Logan provide for the presence of a stabilizer in the design rear suspension. Those owners of the model who have versions without rear stabilizers, it is possible to install them yourself.

Here the unpleasant moment consists in the loss warranty service Renault car Logan, which is in that status. This factor deters many owners from attempting to manually intervene (stabilizer installation) in the factory design.

Running gear features

Rear axle Renault Logan does not provide for the presence of racks, since the design is based on a continuous beam. Initially, this node is able to do without the presence of the elements in question. Fluctuations 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 chassis, then in its design there is a transverse stabilizer bar. The manufacturer declares that the absence given element not able to have a negative impact on reducing the level of safety in traffic. But practice shows: the presence of this detail will not be a hindrance confident behavior car Renault Logan.

How to diagnose?

It is quite difficult to independently diagnose a failed rack when it is necessary to replace the bushings of a stabilizer or other element. The sound of its hinge is very similar to the sound that a worn-out spherical bearing on the lever. If there are other negative sound effects, then you can suspect steering rack Renault Logan in the wear of its elements.

A fairly effective search for the source of a knock will be the impact on each suspension joint individually. To do this, we press the rack with a mount and if this action succeeds, then we definitely resort to replacing the worn part, sometimes it is possible to replace the stabilizer bushings. Most reliable way detection faulty rack stabilizer - its dismantling, after which the worn hinge will emit play under the influence of manual effort.

Replacement

The work involves the presence of a minimum of tools, because the replacement of the stabilizer struts is quite simple.

Stocking up in advance:

• Open-end keys on: "10" and "13";
• Key "TORX T40";
• Head with the 18th standard size.

The procedure is performed according to the following algorithm.

• We hang out in front of Renault Logan by means of jacks. Don't forget to secure your car with car stands. We recommend installing them under the subframe, which is especially important when dismantling not only the racks, but also the stabilization bar itself.
• Before the start of the "operation", we process the threaded sections with a penetrating agent.
• We unscrew the nut from the stabilizer strut fixing bolt, and then knock it out with a hammer.
• Next, unscrew the bolts that fasten the stand itself directly.
• Until the moment the rack is removed, we “throw off” brake hose from the bracket, which will ensure its safety during the designated work.
• The last step is to dismantle the rack mounting bushings (they must also be replaced).
• Having dismantled both racks, we redirect our efforts to remove the bar. Here you should apply the technique of holding the nut with a Torx wrench with a size of "40". We unscrew it and then take out the bushing itself.
• Next, we proceed to unscrewing the two bolts with which the anti-roll bar is fixed to the surface of the subframe.
• We unscrew the nuts fixing the brackets. After these manipulations, the pillows with which the anti-roll bar is equipped are hooked with a suitable screwdriver and removed (can be taken aside).
• Instead of dismantled pillows, it is recommended to install new analogues.

The assembly process is carried out according to the reverse algorithm. In this node, it is desirable to replace the entire list of components, which will allow you to forget about the malfunction for a certain period.

Conclusion

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. this car.
