This is how the elements of the front suspension on the car are located: 1 - front hinge (silent block) front suspension arm; 2 – connecting draft of a stretcher; 3 - shock absorber; 4 – front suspension spring; 5 – rotary fist; 6 - ball bearing rack; 7 – a bolt of fastening of a bar of the stabilizer of cross-section stability; 8 – a bar of the stabilizer of cross stability; 9 - rear hinge (silent block) front suspension arm; 10 - front suspension arm.
Carry out all checks and work from below the vehicle mounted on a lift or inspection ditch (with hanging front wheels).
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, connecting rods, stabilizer bar and its struts, parts of the front end of the body at the attachment points of the suspension units and parts.
Check the condition of the rubber-metal joints, rubber pads, ball joints of the suspension, as well as the 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.
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. Shaking the wheel in a vertical plane, check the ball joints for play. If there is play in the ball pins, replace the bearings.
Note. When shaking the posted front wheel, it is difficult to distinguish play in the hub bearings and in the ball bearings. Ask an assistant to press the brake pedal: if in this case you feel play, then the ball bearings are faulty.
3. Check the rubber bushings and silent blocks in the places where the levers are attached to the body.
4. Check the condition of the rubber bushings at the attachment points of the anti-roll bar to the suspension arms.
5.... as well as rubber pads in the places where the stabilizer bar is attached to the subframe.
6. Check up a condition of a protective cover of a shock-absorber rack.
