2. Remove Wheel

Loosen the lug nuts of the wheel on the side where noise is present.
Lift the vehicle using the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Components

Inspect Struts/Shocks:
- Check for oil leaks, dents, or physical damage.
- If damaged, proceed to replace them.
Check Bushings:
- Inspect suspension bushings for cracks or wear.
- Replace any worn bushings.
Tighten Hardware:
- Ensure all bolts and nuts are tightened to factory specifications.
- Use a torque wrench to apply the correct torque values as specified in the service manual.

4. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and tighten the lug nuts to the specified torque.

5. Test Drive

Conduct a test drive to confirm the noise has been resolved and to ensure proper handling.
