Renault Logan is a budget French B-class car that has been mass-produced since 2004. The car is popular not only in its homeland, but also in Russia. First of all, this car was loved for its reliability and unpretentiousness in maintenance. The car has a simple resource engine and a strong suspension. Renault Logan, in addition, is one of the most affordable cars in its class. Often it is chosen as an alternative to VAZs and for good reason. The car lives up to expectations. But what difficulties can the owner face during operation? In our conditions, the chassis often suffers. Therefore, today we will look at how the suspension is arranged on the Renault Logan and how long its components serve.

Front suspension

Here, the French manufacturer used an independent scheme. This design allows maximum absorption of vibrations and shocks when the car passes through bumps. Basicthe element here is the posts.

They are made according to the "MacPherson" type, that is, the spring and shock absorber are combined together. And so that the racks can carry out a working stroke when hitting a pit, a suspension arm is used. Renault Logan is equipped with simple A-arms that are attached to the power part of the body by means of silent blocks. In our case, this element is connected to the subframe. In order for the drive wheel to be able to change the trajectory of movement, a ball bearing and a steering knuckle are provided. The latter is attached to the rack with two nuts.

Also, the shock strut also has a support (or rather, a thrust bearing). It is located at the top, on the glasses. It is through this bearing that part of the impact is transmitted to the body when hitting an unevenness. The shock absorber is not able to completely level shock loads. Therefore, the thrust bearing must be strong and reliable. According to the owners, its resource is about 120 thousand kilometers. Then it starts to crumble. When cornering, characteristic clicks and crunches are heard. This suggests that the Logan suspension strut support bearing has become unusable.

Stabilizer, hub, steering

To eliminate side rolls, the Renault Logan suspension design has an anti-roll bar. It belongs to the torsion type of stabilizers and is equipped with rubber pads. The element is connected to the subframe with two brackets. Also a stabilizerit is also connected to the suspension arm (however, by means of bolts). It is worth noting that the price of the Renault Logan suspension arm itself is small. The Turkish version costs 1900 rubles.

Hubs are provided for wheel rotation. They are mounted on angular contact ball bearings. On the first versions, they did not last long - only 40 thousand kilometers. The fact is that on cars without ABS there was a through hole in the steering knuckle (it was provided for the sensor). It was through him that the dirt flew into the bearing cavity and thereby destroyed it from the inside. Models after 2006 have been finalized. A special plastic plug was installed on cars, which prevented the passage of water and dirt to the bearing. This significantly increased its service life. Now the wheel bearings on the Renault Logan take care of up to 130 thousand kilometers.

Steering tips are also an integral part of the Logan's front suspension. These elements have a resource of 70 thousand kilometers. If they malfunction, a characteristic knock is noticeable in the Renault Logan front suspension. Ball bearings begin to knock after 100 thousand kilometers. According to the dealer, they change in assembly with levers.

Tie rods have a good resource - 150 thousand kilometers. After this run, play may occur in the inner tips. The rack is a toothed type, capable of serving about 400 thousand. Some owners do not replace the rack (thisthe most expensive element, the cost of which starts from 50 thousand rubles), but simply twist it. So the backlash disappears, but the effort that needs to be applied to rotate the steering wheel increases significantly. This is especially noticeable on vehicles without a hydraulic booster.

Brakes

The front suspension uses disc brakes. The pad resource is 30-40 thousand, depending on the driving style. But the discs wear out after 90 thousand.

CV joints

Special attention should be paid to the left CV joint. Its boot is integrated with the axle oil seal.

Therefore, if the case is damaged, all the oil will flow out of the box. This is fraught with costly transmission repairs. The CV joints themselves go for a long time - from 120 or more thousand kilometers. It all depends on whether the boot was replaced in time.

Rear suspension

It consists of several elements:

• Torsion beam.
• Telescopic dampers.
• Helical springs with top and bottom spacers.
• Rear wheel trunnions with drum brakes and wheel bearings.
• Silent blocks of levers.

Rear of the "Logan" semi-independent suspension. It is based on a twisted type beam. There is also an anti-roll bar at the rear. But it's hard to tell from the outside. This stabilizer is located inside the beam and is tightly welded to the amplifier of the lower arms. Helical barrel-shaped springs also abut here. Unlike the front suspension(where MacPherson struts are used), they are separate from the shock absorbers. The rear chassis does not cause any special problems during operation. The most enduring element is the beam. It is practically eternal. The beam does not rot and does not wear out, with the exception of silent blocks. the latter serve about 200 thousand kilometers. If there is a knock in the area of \u200b\u200bthe rear, most likely, your shock absorber bushings or their rubber pads have worn out. This happens on a run of 70 thousand kilometers. In this case, the shock absorbers are changed entirely and in pairs. They should not be changed separately.

Pads

As for pads, they serve about 120 thousand kilometers in drum mechanisms. But they have to be changed not because of the wear of the friction lining, but because of the wetting from the cuffs of the brake cylinders. As a rule, in this case, both the cylinder and the pads change. Otherwise, the rear suspension does not require attention to itself. This is a fairly reliable and practical design that has been used since the 80s.

In closing

So, we found out how the rear and front chassis are arranged on the Logan. According to reviews, this model uses the most reliable and proven suspension scheme for years. As for repairs and prices, the Renault Logan front suspension requires little investment. For 100 thousand kilometers, its maintenance will take no more than 40 thousand rubles. The rear suspension is even less whimsical and breaks extremely rarely. But if any knock appears in the Renault Logan suspension, you should not delay the repair. Otherwise, shock loads willspread to other elements of the running gear, reducing their resource.
