Solution

1. Preparation

Gather tools and parts needed for suspension inspection and potential repair.
Park the vehicle on a flat surface, engage the parking brake, and wear safety gloves.

2. Tire Inspection

Remove the wheels using a lug wrench.
Check each tire for uneven wear patterns and ensure proper inflation.
Replace any damaged tires as needed.

3. Suspension Component Inspection

Inspect shocks and struts for leaks or signs of wear.
Check control arms and bushings for deterioration or play.
Tighten or replace any loose or damaged components.

4. Wheel Alignment

Use alignment tools to measure and adjust the alignment to the manufacturer's specifications.
Adjust camber, caster, and toe angles as necessary.

5. Final Assembly

Reinstall wheels and torque lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
Lower the vehicle and perform a final visual inspection of all repaired components.
