What does a silent block look like?
This does not cover how to remove the lever or how to reinstall it. We believe that the suspension arm has already been removed, and now the silent blocks need to be replaced. With the lever removed, diagnose the condition of the ball joints. If the ball joint needs to be replaced, then read the material: which ball joint is better to choose?
Each silent block consists of two bushings inserted into one another. There is a rubber coupling between the bushings. The outer sleeve is pressed into the metal. And the inner one should be clamped by the cheeks of the subframe, which are tightened with a screw and nut. Hence the conclusion: do not tighten the lever fastening without installing the car on the wheels. Otherwise, the coupling will remain twisted and the silent block will not last long. Read more in the material about the structure of the front suspension on Renault Logan.
Now - the crimping process. Any silent block resembles the letter “T”, and the lower crossbar of this letter must fit into the mandrel (see photo).
The upper crossbar, in turn, is pressed by a metal washer. The entire structure is tightened with a screw.
When performing crimping, do not put pressure on the inner sleeve! So only use suitable mandrels and washers.
DIY Largus suspension repair
It’s easy to understand how important suspension is in a modern car by taking an ordinary cart as an example. As a rule, driving on bumpy roads on it is not synonymous with comfort. In order to smooth out all the irregularities and dampen vibrations as much as possible, rear and front suspensions were invented. In addition, this system connects the wheels to the body.
The purpose of all pendants is the same. But the design features are different. For example, Lada Largus is a representative of the budget class on the B0 platform and has a simple suspension arrangement.
Replacing the ball joint of the front suspension of a Lada Largus car
Possible knocking noises from the front suspension may be caused by ball joints. A faulty joint can be identified by touch by the play of the ball pin. We replace this hinge.
We check the condition of the dirt-proof covers of the hinges. We replace the hinges with torn covers as an assembly.
On the new ball joint, rotate or tilt the ball pin in different directions. Play, easy movement of the finger or severe jamming are unacceptable.
We prepare the car for the job. We install the car on a viewing hole or lift.
Remove the front suspension arm assembly with the ball joint (see How to remove the front suspension arms of a Lada Largus)
Use a powerful screwdriver to pry the support body under the shoulder (Figure 1)
Leaning on the edge of the lever, we press the ball joint out of the hole in the lever.
We inspect the lever eye - there should be no cracks or breaks around the hole. Before pressing in the new ball joint, thoroughly clean the seating surface of the lever hole from dirt and corrosion. Place a tool head or a piece of pipe of suitable diameter under the lever and insert a new ball joint into the hole.
By striking the mandrel with a hammer (Figure 4, you can use a tool head) resting on the shoulder of the support body, we press the support into the hole of the lever until it stops. We carry out further assembly in reverse order.

The shelf life of rubber is 5 years. For fluorine rubber the figure doubles
In general, when choosing spare parts, pay attention to the date of manufacture. Pure rubber is not used in the manufacture of silent blocks, but it is better not to buy something that was produced 7 or 8 years ago.
Removing and installing the front suspension arms of the Lada Largus car
We remove the front suspension arms for replacement or repair. Damage to the lever can be:
- deformation of the lever itself;
— wear of the ball joint;
— wear of silent blocks.
The work to remove the left and right front control arms is identical.
Operations to remove the lever must be carried out with the front of the car suspended or the car completely raised on a lift. When hanging one wheel, the anti-roll bar will create a load and interfere with the removal of the lever.
To remove the lever, remove the wheel.
Disconnect the stabilizer bar mount (How to remove the front suspension stabilizer of a Lada Largus).
Remove the engine protection from below.
Using a 16mm socket, unscrew the nut of the coupling bolt of the terminal connection between the steering knuckle and the ball joint pin, holding the bolt with a wrench of the same size.
We take out the bolt or knock it out with a soft metal drift.
Using a powerful slotted screwdriver or a spatula, loosen the connection between the steering knuckle and the ball joint pin.
At the same time, shaking the steering knuckle from side to side by the brake disc, we remove the ball joint pin from the hole in the steering knuckle.
Use a 13 socket to loosen the bolt securing the subframe bracket to the body.
Using a 18 mm socket, unscrew the nut securing the subframe bracket
Remove the bracket from the front bolt securing the arm to the subframe
Using an 18-mm socket, unscrew the nut of the rear lever mounting bolt, holding the bolt with a spanner of the same size.
We take out the bolt or knock it out with a soft metal mandrel.
Similarly, unscrew the nut of the rear lever mounting bolt and remove the bolt.
Remove the suspension arm.
Install the lever in reverse order.
The nuts of the bolts securing the lever to the subframe are finally tightened.
Tightening torques for fasteners of assembly units during installation:
— Nut of the coupling bolt of the terminal connection of the steering knuckle and the ball joint pin 62 Nm
— Nut of the bolt securing the suspension arm to the subframe 105 Nm
— Nut securing the subframe bracket to the front suspension arm bolt 62 Nm
— Bolt securing the subframe bracket to the body 21 Nm
— Nut of the screw securing the stabilizer bar to the suspension arm 14 Nm

Removing “old” silents
When carrying out a replacement, the most difficult thing will be to get rid of the “old” silent blocks. The steps look like this: fix the lever and use a drill d=3-4 mm to make a set of holes in a circle. Then, using a jigsaw, installing a file with a fine tooth (“A” or “B”), we cut the rubber. You can also use a regular jigsaw here.
At the last step, having laid wooden blocks, the lever is secured in a vice. The outer sleeve is sawed with a hacksaw. And try not to touch the metal of the lever so that it does not rust.
In theory, replacing the silent blocks of the Renault Logan front control arms looks no more difficult or easier than on any other car. Many people say that the “old” silent block can simply be knocked out. But it seems that they did not encounter a replacement.
Case from practice
You can hear from owners that rubber can be easily cut with a knife. Maybe this is true when the mileage is about 100 thousand km.
At a mileage of 170 thousand, many of the bushings crumble. In theory, it remains intact, but only until the lever is removed.
If the mileage is short, stock up on a drill and jigsaw. Well, and patience, of course, too.
Features of operation
The most important nuance of operation is that it is almost impossible to check their characteristics after installation on a vehicle. This is due to the fact that very often parts simply break at the joint junction, that is, where they come into contact with the lever. In addition, if the ball is not suitable for Largus, then, naturally, it will not achieve the unambiguous trust of the master - it is simply impossible to check.
Causes of failure
If this level of wear is too strong and the entire load in Largus is distributed unevenly on the two ball joints, then this leads to the pins being pulled out of the housings. The consequence of this is the impossibility of supporting the wheels and, accordingly, the car falling onto the asphalt.
In addition, the natural wear and tear of parts can be “loaded” with obsolete materials. Due to the increase in dynamic load and considerable speed of movement, they are simply not able to perform their functions.
Crimping process
The main goal is to ensure that the distance between the outer edge of the silent and the plane of the lever becomes 7 mm. There is no need to do less!
To carry out all actions, you will need two gas or Swedish keys. A screw with washers (puller) and a set of mandrels are also used.
All equipment shown above was taken from the repair kit for the VAZ-2109. A lubricant is usually applied to the screw thread: cyatim, litol, etc.
Sequence of actions
First, clamp the lever in a vice. Then we assemble the structure as shown.
The details go in this order:
- Bottom nut;
- Bottom washer;
- Mandrel with liner;
- Upper washer (it presses on the silent block);
- Second nut.
Once again, make sure that the inner sleeve remains free. The two nuts on the screw must be tightened, checking the result with a caliper.
Owner reviews
Replacing the silent blocks of the Renault Logan front levers is successfully carried out in one case: during installation, a force of 100-120 N*m must be applied. It's a lot. There is often concern that the thread may break. The “VAZ kit” was not designed for such loads. In general, all of these actions are carried out at your own peril and risk.

You can use the silent block of the front lever of the Lada Largus on the dashboard to improve the appearance of the torpedo. Two light bulbs don’t burn out at once, so it’s shorted out somewhere, look at the fuses first, if everything is fine, then look in the wiring somewhere, a wire to ground is shorted to something electrical. I was most inclined towards wheel bearings, which turned out to be correct. And don't tell me that you need to use second gear, because sometimes you need to accelerate quickly, and this is only possible in first. With the engine off, Lada Vesta cross. Four-spark distributor, 4 mm from the top.
A bushing made of sheet tin bronze is pressed into the hole in the rocker hub. The streamlined body of the seven will help remove the incoming air flow from under the bottom. If the vehicle has been in use for quite a long time, combustion deposits will form on the liners and gaskets. You take a thicker copper wire and solder it on top of the burnt track.
It is important to focus on modern motorists; this is a characteristic feature of all transmissions of this type. These armrests are available in a variety of gray and black colors with a removable zippered cover made of fabric or leatherette
You can easily break it in any road pothole or by carelessly driving onto a curb.

Choosing a ball joint for Renault Logan, Sandero, Lada Largus
I’m thinking about how to unscrew 2 bolts from the arms and 4 nuts from the body, which will be useful to you. I blew out the entire system from the silent blocks of the front arms of the Lada Largus, the hose separator to the adsorber. Lock the split gear, assemble the engine and start it. I immediately suspect the closer block, now in 30 seconds if necessary. In modern models, dampers and regulators rarely fail, due to the fact that aluminum is used for their manufacture at the factory. Press out the front and rear oil seals.
During the work, it is necessary to defecate the suspension units, especially the ball joints and silent blocks. If the red triangle lights up while the engine is running, then you should diagnose the brake force distributor; sometimes the cause of the indication is a malfunction in the electronics. Step-by-step instructions for installing power windows on a Lada Granta prepared by online store specialists. There are 3 of them separately from everyone else and 3 fuses. When installing new brake pads, it is necessary to press the piston into the caliper, as in some cases it can come out strongly and make it impossible to install new pads. In this case, it is recommended to sharpen the discs.
