For normal and safe operation of the car, it is required to periodically carry out maintenance. service. Malfunctions of the suspension struts directly affect the safety of driving, so it is imperative to check their condition.
Checking the health of the shock absorbers is not difficult, and it is quite possible to do it yourself. Modern telescopic racks are non-separable, therefore, if defects are found, they are replaced with new ones.
Check in motion
The initial check of the suspension struts of the VAZ - 2109 car is carried out "by ear" when driving on an uneven road. Extraneous knocks in the area of the struts or "breakdown" of the suspension indicate their malfunction.
Defective racks can only be replaced by a pair /
If the front or rear of the car is swinging strongly or, as they say, "dancing", then this also means that the shock absorbers are out of order and must be replaced.
Basic check
A further check is carried out with the vehicle at a standstill. To do this, it is necessary to apply strong pressure to the body above each pillar. With the struts in good condition, the car should make no more than one oscillatory motion.
Next, conduct an external inspection of all racks. The working shock absorbers must be free of liquid drips, any damage or deformation. Then check the strut springs for cracks or breakages.
If the suspension is constantly triggered to the stop - "breaks through", then this means that the springs have exhausted their resource and must be replaced. It is impossible to operate such a car, since the body can be deformed.
Then check the condition of the spring cups for cracks or deformation. The compression damper must also be intact and free from mechanical damage.
Before disassembling the rack, it is necessary to compress the spring with a special puller /
Disassemble the telescopic racks removed from the car and conduct a thorough inspection and troubleshooting. The shock absorbers of the struts must be dry and clean, with no visible signs of wear. The shock absorber must be checked before installation.
Checking the smoothness of the stroke of the shock absorber rod is carried out only on a vertically installed rack. To do this, insert a large screwdriver into the lower hole for the mounting bolt, step on it and pull the stem up or press down. On a serviceable shock absorber, the rod moves smoothly, without jamming or failures.
When inspecting the thrust bearing, it should rotate easily and quietly and also free from cracks or damage. Worn out dampers must be replaced with new ones.
