Regular checks of the steering linkage and suspension are necessary to prevent tire wear, ride quality issues, handling problems, and reduced fuel efficiency. Park the vehicle on level ground, turn off the engine, and engage the parking brake. Push down on each corner of the vehicle to check the shock absorbers; if there is continuous bouncing or failure to return to the original position, the shock absorbers may be worn or weak. Inspect all four corners and raise the vehicle if needed to check for fluid leakage from the shock absorbers. Replace them as a set if there is leakage. Also, visually inspect the steering system components for damage, leaks, and worn seals, boots, and fittings. Check the steering knuckle-to-control arm joint for movement and the front tires for play in the steering system. If there is play, tighten the steering gear mounts and inspect tie-rod ball joints. While the vehicle is raised, check the rear drive axle CV joint boots for damage or leaking grease.
