During each maintenance and repair, it is imperative to check the condition of the protective covers of the ball bearings of the suspension, the covers must not be mechanically damaged.
Find out if there are any cracks on the suspension parts or traces of rubbing against road obstacles or the body, deformation of the levers, the stabilizer bar and its struts, the body front parts in the places where the suspension units and suspension parts are attached.
Check the condition of rubber-metal joints, rubber pads, suspension joints, condition (draft) upper supports of telescopic suspension struts.
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.
Pic. 1. Front suspension (left-hand side): 1 - suspension arm bracket; 2 - shock absorber; 3 – rotary fist; 4 - ball bearing; 5 – front suspension arm; 6 - front suspension subframe
The arrangement of elements of a forward suspension bracket on the car is shown on fig. 1.
On rubber suspension parts are not allowed:
- signs of rubber aging;
- mechanical damage.
On rubber-metal hinges are not allowed:
- signs of aging, cracks, one-sided bulging of the rubber mass;
- separation of the rubber mass from the reinforcement.
Replace defective parts.
Attention! Pay special attention to mechanical damage (deformations, cracks, etc.) suspension components, especially control arms.
1. Check up a condition of protective covers of spherical support. If the boots are damaged, replace the ball joint assemblies.
2. Check the ball joints for play. To do this, insert the mounting blade between the steering knuckle and the suspension arm and, leaning on the lever, try to shake the steering knuckle. If there is play in the ball stud, replace the front suspension arms as an assembly.
3. Check with a mounting blade the condition of the front..
4.... and rear hinges of the front suspension arms. Resting the mounting blade against the subframe, try to shake the suspension arm. If there is play in the hinges, they must be replaced.
5. Check the condition of the top…
6.... and the lower hinges of the stabilizer bar struts.
7. While shaking the anti-roll bar by hand, check the condition of the pads attaching it to the subframe. If there is knocking, replace the pillows.
8. Check up a condition of a protective cover of a shock-absorber rack.
