With the vehicle on the ground, perform a series of checks and inspections to assess the condition of various components. Begin by gently rocking the steering wheel while the vehicle is stationary to detect excessive free play, which could indicate worn front wheel bearings, steering shaft universal joints, lower arm ball joints, or steering gear. Keep an eye out for other symptoms like excessive body movement over rough terrain, swaying around corners, and steering wheel binding as you turn, as these may signal issues with steering or suspension components. Evaluate the condition of struts and shock absorbers by pushing down and releasing the vehicle at each corner; if it fails to return to a level position within one or two bounces, the shocks/struts are worn and require replacement. Listen for squeaks and noises from the suspension components during this test. Examine struts and shock absorbers for fluid leakage, but note that a light film of fluid is generally not a cause for concern. Ensure that any observed leakage originates from the struts/shocks. If leakage is confirmed, replace the struts/shocks as a set. Verify that struts and shocks are securely mounted and undamaged and inspect upper mounts for wear or damage; replace shocks as a set (front and rear) if needed. Move under the vehicle by raising it and supporting it securely on jackstands. Check the tires for irregular wear patterns and proper inflation, and inspect the universal joint between the steering shaft and steering gear housing, steering gear housing for lubricant leakage, and the condition of dust seals and boots. Examine the steering linkage for looseness, damage, and play in the tie-rod ends, and inspect all suspension and steering components for loose bolts, broken or disconnected parts, and deteriorated rubber bushings. While an assistant turns the steering wheel, assess steering components for free movement, chafing, and binding, aiming to pinpoint any slack. Investigate ball joints for wear by attempting to move each control arm up and down to check for play. Replace any ball joint with play. Inspect ball joint boots for damage and grease leakage, replacing damaged boots. Finally, pay attention to the CV boots, washing them to remove oil and grease that could accelerate deterioration. Focus on the outer CV boot, as it wears out more quickly due to constant pivoting. Inspect the boots for tears, cracks, and loose clamps.
