How to fix a knocking and creaking suspension | CarTipsandmore

  1. Check the shock absorbers.
    Make sure there are no oil leaks.
  2. Check the bushings.
    If they have loose components or cracks in the rubber parts, it means they are worn out.
  3. Check the ball joint.
    Check that the protective cap is not cracked and that there is not too much play in the housing.
    A knocking sound when cornering is the most common sign of a bad ball joint.
  4. Observe how the wheels work.
    If the car is off track and the steering wheel angle has decreased, carefully inspect the steering knuckle.
  5. Check the arms, paying special attention to their fasteners and seals.
  6. Check the steering system.
    Check the tie rods and tie rod ends if you notice the steering wheel wobbling and you hear unusual noises.
    If these steps have identified the problem, replace the defective part.
    If not, you will need to contact a repair service.
