Having lowered the VAZ 2108, VAZ 2109, VAZ 21099 car to the ground, rock the car several times. Tighten the nuts securing the ball joint to the front suspension arm and securing the front suspension arm to the body bracket to a torque of 80-96 Nm (8.0-9.6 kgf-m), the nut securing the brace to the front suspension arm - 160-180 Nm (16. 0-18.0 kgf-m), nut securing the stabilizer bar to the front suspension arm - 42-52 Nm (4.2-5.2 kgf-m). After driving 100 km, tighten these threaded connections again to the required torque.
How to replace the front suspension arm of a VAZ 2109
The lever is one of the main elements of the entire unit in the front suspension of the VAZ 2109. The lever must be replaced, as a rule, only in the event of severe collisions of the vehicle, or if it falls into a hole or hatch. The lever should be changed using a special pit; in such conditions it will be more convenient for you to work and see all the details. But if this is not possible, then you can use a regular jack.
Replacing the lever is not a very difficult process, and it is quite possible to replace it yourself. First you need to remove the wheel and at the same time secure the car by resting it on something stable. The next step is to unscrew the ball nut and remove it from the lever. Next, loosen the rear nut and unscrew the stabilizer strut mount. Then unscrew the bracket. Then you can pull out the lever with a slight movement.
Next, inspect the condition of the front suspension and check it for other defects and breakdowns. Then replace the joints and the entire lever. In the same sequence, only in reverse order, screw all the parts back.

Notes:
It is necessary to carefully inspect the suspension arm and replace it in the following cases:
a) the geometry of the lever is broken;
b) rubber-metal hinges are torn, swollen on one side or their rubber has lost its elasticity.
Replacing rubber-to-metal lever joints requires special tools and skill. In garage conditions, it is easier to replace the entire lever assembly.
Install the lever in reverse order. Having lowered the car to the ground, you need to rock it strongly several times. Tighten the nuts securing the ball joint to the lever and securing the lever to the body bracket with appropriate torques.
After driving 100 km, we tighten these threaded connections again to the required torques.
Replacing shock absorbers on the front suspension of a VAZ 2109
It is enough when repairing the front suspension of a VAZ 2109; it is also necessary to replace the shock absorbers. You can understand that it is time to change the shock absorbers by hearing shocks while driving. Most often this indicates that the springs have broken or the shock absorber has lost its elasticity. Springs and shock absorbers can only be replaced in pairs.
Replacement process:
- First you need to remove the front strut. Then take it apart. However, it will not be possible to repair the wheel corners.
- You need to remove the wheel and turn the steering wheel all the way. Unscrew the nut with a wrench while removing the cotter pin.
- Remove the stand holder. Remove the plug and loosen the shock absorber rod nut.
- Place a mounting mark on the bolt. Remove the bolt.
- When reassembling, it is necessary to achieve alignment of the marks, then the deviation of the wheel angles will be less.
- Next, unscrew the upper and lower bolts and remove the adjusting washer.
- Unscrew the nuts that connect the strut support and the body. Install two zip ties onto the springs. In this case, the ties must be opposite to each other.
The front suspension of the 2109 can often break down, causing a lot of trouble for its owner. To avoid problems and frequent breakdowns of the 2109 suspension, it is necessary to promptly diagnose your car and, in the event of any malfunction, urgently check and inspect it, and if it is severely damaged, replace it. If you yourself are not able to repair the front suspension of the VAZ 2109, it is better to take the car to a car service center, where experienced technicians will quickly and efficiently repair your car. If this is not done in a timely manner, bad consequences may occur.
What problems can there be and how to fix them
The condition of the front suspension should be monitored regularly. The most common damage is abrasion of the joint covers. These damages are classified as mechanical. Among the malfunctions of this element of the car, unevenness of the lever located on the suspension or on the stabilizer bar is noted. This may result in incorrect and inaccurate operation. In all these cases, you need to check the parts and then simply replace them with new ones.
Among the malfunctions there may be minor ones that should be eliminated using a regular repair kit. For example, loosening the bolts of the stabilizer bar or the nut of the support. You should tighten them tighter.
If you hear the suspension making sounds (knocking, creaking), then this indicates more serious damage. First you need to determine where the sound is coming from. You can use a jack for this. Rock the wheel in a vertical plane; if there is a knock in the center of the wheel, then most likely there is a fairly large gap in the bearing. It is better not to change the bearing yourself, as it can be destroyed. It is better to contact a car service center that has special equipment for these purposes.
We draw conclusions: it is better to diagnose and prevent your car and protect yourself while driving than to invest in tuning.
