Set the front wheels to drive straight and turn the steering wheel slightly in different directions to determine the free play of the steering wheel. Freeplay is the angle that the steering wheel turns before the front wheels begin to turn. Excessive play can be caused by worn hub bearings, lower arm ball joint, steering shaft universal joint, or steering gear.
Check up serviceability of the shock-absorber, having shaken a body for its corner. The body must return to its original position after it is released. If the body rises above its original position and continues to sway, most likely the shock absorber located on this side is out of order and must be replaced. Check the shock absorber mount for wear.
Place the car on a lift.
Check tire wear and condition.
Check the condition of the universal joint between the steering shaft and the steering gear housing.
Check the steering gear housing for fluid leaks.
Visually inspect the ball joint mudguards and the rack and pinion steering gear guards for cracks, abrasions and ageing. Any damage to the boots leads to loss of lubricant, water and dirt ingress and, as a result, rapid wear of the ball joints or the steering mechanism.
While the assistant turns the steering wheel from side to side, check the steering parts and assemblies for wear and tightness.
Check the condition and play of the hinges of the lower levers by trying to move the levers relative to the wheel disk up and down with a mounting blade.
At the rear of the vehicle, inspect the rear suspension arm bushings.
