2. Inspect Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Remove the wheels to gain access to the suspension components.
Inspect the shock absorbers/struts for leaks or physical damage; replace if necessary.
Check sway bar links for play; replace any worn or broken links.

3. Tighten Loose Components

Tools Required: Socket set, torque wrench
Use a torque wrench to ensure all bolts and nuts on the suspension components are tightened to manufacturer specifications.
Inspect and tighten any loose brackets or fasteners found during the visual inspection.

4. Replace Worn Bushings
