The steering linkage and suspension components should be checked periodically. Worn or damaged suspension and steering linkage components can result in excessive and abnormal tire wear, poor ride quality and vehicle handling, and reduced fuel economy. To check the strut and 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. Raise the vehicle and support it securely on jackstands. Check the struts/shock absorbers for evidence of fluid leakage. A light film of fluid is no cause for concern. Make sure that any fluid noted is from the struts/shocks and not from some other source. If leakage is noted, replace the struts/shocks as a set. Check the struts/shocks to be sure that they are securely mounted and undamaged. Check the upper mounts for damage and wear. If damage or wear is noted, replace the struts/shocks as a set. Visually inspect the steering and suspension components for damage and distortion. Look for damaged seals, boots and bushings and leaks of any kind. Examine the bushings where the control arms meet the chassis. Clean the lower end of the steering knuckle. Have an assistant grasp the lower edge of the tire and move the wheel in-and-out while you look for movement at the steering knuckle-to-control arm balljoint. If there is any movement the balljoint must be replaced. Grasp each front tire at the front and rear edges, push in at the front, pull out at the rear and feel for play in the steering system components. If any freeplay is noted, check the tie-rod ends for looseness or wear.
