Check that suspension components are not sagging due to wear. Conduct a visual inspection for any changes in the suspension while parking the vehicle on a level, horizontal surface. Suspension problems usually only occur after a vehicle has been driven for a long time and are more noticeable on the driver's side.
Shift into gear and apply the parking brake. Grasp the steering wheel with both hands and turn it left and right. Listen for any unusual sounds or metallic noises. Check the steering wheel free play. If you find one, have an assistant rock the car until the source of the problem is identified.
Check your shock absorbers, as they are more susceptible to wear than other suspension components. The following are characteristic signs indicating a faulty shock absorber:
- prolonged rocking of the body when driving on uneven road surfaces;
- increased body vibrations when driving on uneven road surfaces;
- uneven and unstable movement of the wheels (bouncing) when driving in a certain speed range, including when turning;
- deviation from the intended trajectory of the vehicle's movement during braking;
- unstable cornering and skidding of the car;
- increased tire wear, characterized by wear of the tread pattern;
- the appearance of clicks and extraneous noise when the vehicle is moving. Clicking and thumping sounds can also be caused by other suspension faults, such as loose threaded connections, failed wheel bearings, or worn constant velocity joints on the wheel drive shafts.
If any signs of fluid leakage appear, the shock absorbers must be replaced. Replace shock absorbers in pairs on one axle of the vehicle, except in cases where the breakdown occurred on a new vehicle without sufficient mileage.
