Checking the technical condition of the rear suspension parts on the car

Pic. 7.2. Arrangement of elements of a back suspension bracket on the car: 1 – a cross-beam of a back suspension bracket; 2 – a bar of the stabilizer of cross stability; 3 – a spring of a back suspension bracket; 4 - bracket for attaching the stabilizer bar to the cross member of the rear suspension; 5 - rear suspension shock absorber; 6 - front lower rear suspension arm; 7 – trailing arm of the rear suspension; 8 - the upper arm of the rear suspension; 9 – a rack of the stabilizer of cross stability; 10 - rear lower rear suspension arm

Carry out all checks and work from below the vehicle mounted on a lift or inspection ditch (with hanging rear wheels).

Find out if there are cracks on the suspension parts or traces of rubbing against road obstacles or the body, deformation of the levers, stabilizer bar, rear body parts at the attachment points of suspension units and parts.

Check the condition of rubber-metal hinges, rubber cushions, condition (draft) suspension springs.

Rubber-metal hinges and rubber pads must be replaced in case of ruptures and one-sided buckling of rubber, as well as when cutting their end surfaces.


The arrangement of elements of a back suspension bracket on the car is shown on fig. 7.2.

On rubber-metal hinges are not allowed: - signs of aging, cracks; – one-sided buckling of the rubber array.

Replace defective parts.

Check for mechanical damage (deformations, cracks, etc.) suspension elements.



1. Inspect the bottom mount rubber bushings…



2….and the hinge of the top fastening of the shock-absorber 5 (see fig. 7.2) and shock absorbers. Shock absorbers are not allowed to drip liquid and fogging.

3. Check the rubber joints (silent blocks) trailing arm of the rear suspension to the car body.



4. Using a mounting spatula, check the silent blocks of the rear lower arms for play.




5. Using a mounting spatula, check the silent blocks of the front lower rear suspension arms for play.

6. Similarly, check the silent blocks of the upper arms of the rear suspension.



hh7. While rocking the anti-roll bar up and down, check for play in the stabilizer link and the rubber pads on the stabilizer bar.

8. Check springs 3 (see fig. 7.2) and compression buffer.

USEFUL ADVICE: Pay attention to the exhaust system. Extraneous knocks published by her are often mistaken for a knock in the rear suspension. The use of non-standard parts or the breakage of the muffler suspension elements can cause a strong knock, especially during regassing. To check, stop the engine, carefully inspect the exhaust system, check the reliability of the mounting and suspension of the muffler. Grasping the end of the exhaust pipe, shake the muffler up and down and from side to side - there should be no knocking.
