In this article we will consider the main faults that occur in the car suspension and methods of correction

Front suspension: 1 - front disc; 2 - cross member; 3 - front subframe; 4 - front lower arm; 5 - front stabilizer assembly; 6 - Front stabilizer bar mount

Fault

- Probable cause - Remedy

Tight steering:

  • - Incorrectly adjusted front wheel alignment - Adjust front wheel alignment
  • - Excessive resistance to rotation of lower arm ball joint - Replace ball joint
  • - Low tire pressure - Adjust tire pressure
  • - Power steering does not work - Repair or replace power steering

Steering wheel does not return to its original position clearly enough:

  • - Incorrectly adjusted front wheel alignment - Adjust front wheel alignment wheels

Hard, uncomfortable ride:

  • - Front wheel alignment is incorrectly adjusted - Adjust front wheel alignment
  • - Shock absorber is malfunctioning - Replace shock absorber
  • - Damaged or worn stabilizer - Replace stabilizer
  • - Damaged or worn coil spring - Replace coil spring
  • - Lower arm bushing is worn - Replace lower arm
  • - Low tire pressure - Adjust tire pressure

Uneven tire wear:

Front wheel alignment is incorrectly adjusted, shock absorber is malfunctioning - Adjust front wheel alignment wheels. Replace the shock absorber

The car "yaws":

  • - Incorrectly adjusted front wheel alignment angles - Adjust the front wheel alignment angles
  • - Worn lower arm ball joint - Replace the ball joint
  • - Worn lower arm bushing - Replace the lower arm

The car pulls to one side:

  • - Incorrectly adjusted front wheel alignment angles. Bent lower arm
  • - Excessive resistance to rotation of lower arm ball joint - Replace ball joint
  • - Damaged or worn coil spring - Replace coil spring
  • - Bent lower arm - Replace lower arm

Angular oscillation of steering wheels:

  • - Incorrectly adjusted front wheel alignment - Adjust front wheel alignment
  • - Worn lower arm ball joint - Replace ball joint
  • - Damaged or worn stabilizer - Replace stabilizer
  • - Worn lower arm bushing - Replace lower arm
  • - Shock absorber malfunctioning - Replace shock absorber
  • - Damaged or worn coil spring - Replace coil spring

Vehicle suspension sag:

  • - Damaged or worn coil spring - Replace shock absorber
  • - Shock absorber malfunctioning - Replace coil spring

Abnormal noise:

  • - Suspension components not tightened enough - Tighten suspension components
  • - Damaged or worn wheel bearings - Replace wheel bearings
  • - Damaged shock absorber - Replace shock absorber
  • - Damaged tire - Replace tire

Unstable vehicle movement:

  • - Low tire pressure - Adjust tire pressure
  • - Shock absorber is malfunctioning - Replace shock absorber
  • - Wheel mounting nuts are not tightened - Tighten wheel mounting nuts to 88.3-107.9 Nm
Wheel hub mounting nuts tightening procedure
  • - Loss of elasticity or damage to coil spring - Replace coil spring spring

The car body is tilted to one side:

  • - Damaged tire - Replace tire
  • - Worn bushing - Replace bushing
  • - Deformed suspension components - Replace suspension components
  • - Loss of elasticity or damage to coil spring - Replace coil spring
