Minimizes spring bounce and helps keep the wheels in contact with the road.

Signs of Wear:

Excessive ball joint play, leaking oil along the shock body, broken mounts or mounting hardware, worn or missing bushings, excessive vehicle bounce, cupped tire wear.

Did You Know?

Tire pressure and vehicle ride height are two of the most neglected suspension-related items. Lack of attention to these areas can contribute to improper wheel-alignment and unnecessary chassis part wear. If the ride height of a vehicle falls below the manufacturer’s specification (due to wear or incorrect loading), the entire suspension system suffers. This in turn reduces your vehicle’s braking, steering and acceleration capabilities and increases tire wear.

What It Does:

The Ride and Handling System supports the vehicle’s weight, keeps the wheels in contact with the road and helps provide a comfortable ride for the passengers.

Service & Maintenance:

Regular maintenance of your vehicle’s suspension plays a major part in its handling characteristics, how it feels on the road and how it steers during an emergency. A visual inspection and chassis lubrication are recommended with every oil change while a thorough annual inspection of the suspension is recommended as well. Regular suspension maintenance also improves tire wear. A car with misaligned wheels and/or worn shocks can cause tires to wear out faster than normal. Consult your Owner’s Manual for your manufacturer’s recommended tire-rotation and wheel-alignment schedule to keep your vehicle running smoothly.

Areas to Inspect:

  • Leaking oil or wetness along the body of the shock or strut
  • Broken mounts, worn or missing bushings
  • Broken, damaged or missing mounting hardware
  • Severely dented reservoir tube, bent or scratched piston rod
  • Cupped tire wear
  • Damaged strut body springs, seats and bushings
  • Defective strut bearing or plate missing
