Remove the wheel to gain access to the suspension.
Check the control arms, struts, and shocks for any signs of wear or damage such as cracks or leaks.
Use a pry bar to check for play in the bushings and joints.

3. Tighten Loose Fasteners

Inspect all mounting bolts and nuts on the suspension components.
Use a torque wrench to tighten any loose bolts to the manufacturer’s specified torque settings.
Pay particular attention to strut mounts and sway bar link connections.

4. Replace Worn Parts

If any worn or damaged components are identified (e.g., bushings, sway bar links), remove and replace them.
Ensure to use OEM or quality aftermarket parts for reliability.

5. Reassemble and Lower Vehicle

Reattach the wheel and lower the vehicle back to the ground.
Make sure all tools are accounted for and that no parts are left loose.
