CORRECT OPERATION
Shock absorbers resist compression or extension by forcing hydraulic fluid through small valves. The fluid is vital for correct operation. The shock must not leak fluid.During vehicle operation, signs of a worn shock absorber or strut include:
- Car rolls (leans) on turns.
- Car "bottoms out" with a thud after hitting a bump. This can cause damage to components underneath the car such as the oil pan, transmission pan, or exhaust system.
- Rear end squats when accelerating.
- Front end dives when braking.
- Car slides or bounces along rough, winding road.
If these conditions occur, have the shocks or struts replaced immediately. Otherwise, additional parts of the car could be damaged. These parts include the tires, springs, constant velocity joints (if front-wheel drive), steering linkage, and ball joints.
