Regular checks of steering linkage and suspension components are crucial to prevent tire wear, poor ride quality, and abnormal handling. To test shock absorbers/struts, push down at each vehicle corner; if it doesn't return to level within two bounces, they may be worn. Check for fluid leakage and replace if necessary. For suspension and steering, push and pull each front tire to detect play in the system. Inspect tie-rod ends, ball joints, and steering gear boots for damage or looseness. If boots leak lubricant, consider replacing the steering gear. Lastly, check drive axle boots for damage and replace if needed.
