The strut/shock absorber assemblies cannot be serviced and must be replaced if there is a problem. However, there may be strut assemblies available with springs on an exchange basis, which can save time and effort.

Unbolt the brake hose bracket from the strut and disconnect the upper end of the stabilizer bar link. Mark the exact position of the strut to the steering knuckle and remove the strut-to-knuckle bolts and nuts.

Finally, remove the shock absorber.

Park the vehicle on level ground, turn the engine off and set the parking brake. Check the tire pressures. Push down at one corner of the vehicle, then release it while noting the movement of the body. It should stop moving and come to rest in a level position within one or two bounces. If the vehicle continues to move up-and-down or if it fails to return to its original position, a worn or weak shock absorber is probably the reason. Repeat the above check at each of the three remaining corners of the vehicle.
