To observe the steering and suspension parts in detail, refer to the shock absorbers by parking the vehicle on a flat surface, disabling the engine, and making sure the parking brake is in place while checking tire pressures. Press down on one side of the vehicle and release it; the body should cease bouncing and return to a level state in one or two bounces. If it still moves or does not resume its initial position, it is probable that there is a worn or weak shock absorber. Check this at the other corners. Lift the car and place it firmly on jack stands, and examine the shock absorbers; a bit of a light film is fine, but any serious leakage of fluid should lead to a replacement of the shocks as a set. Make sure that the shocks are well mounted and intact, and examine upper mounts to find out whether they are damaged or worn out, which requires replacement as a system too. The second step is to check the tires for abnormal wear marks and correct inflation, the universal joint used between the steering shaft and the gear housing for leakage of lubricants, and finally make sure that the dust boots are still in place with clamps fastened. Check tie rod ends for excessive play and search for dislocated bolts, worn parts, or rotting rubber bushings on all suspension and steering parts. When the assistant is rotating the steering wheel, monitor the steering parts to see whether they are free moving or bound. The wear of the ball joints can be measured by trying to raise and lower each control arm using a pry bar; any movement is an indication of a worn ball joint, and the control arm will have to be replaced due to the non-removable nature of the ball joints. Check ball joint boots and tie-rod end boots to see whether they are damaged and seeping grease. Lastly, verify the CV Joint Boots that play an important part in preventing dirt and foreign material from destroying the constant velocity joints. Clean and check these boots regularly for tears, cracks, and loose clamps, and replace them in case there is any sign of wear or leaking lubricant.
