- Secure with jack stands to ensure stability.
Remove Wheel:
- Use a socket set to remove the lug nuts and take off the wheel for access to suspension components.
Inspect Struts and Shocks:
- Check for any leaks or physical damage.
- If damaged, remove the strut/shock assembly:
  - Disconnect any wiring harness or connectors.
  - Remove the mounting bolts using a torque wrench.
Examine Sway Bar Links and Bushings:
- Check the sway bar links for any signs of wear or looseness.
- If needed, remove the sway bar link using a socket set.
Reinstall or Replace Components:
- If components are worn, replace them with new parts.
- Reinstall struts/shocks and sway bar links, ensuring all bolts are torqued to manufacturer specifications.

3. Reassemble the Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then fully tighten the lug nuts in a crisscross pattern.

4. Test Drive

Take the vehicle for a test drive over bumps to ensure the noise has been resolved.
