- Remove the wheel to gain access to the strut assembly.
- Inspect the struts for any fluid leaks or physical damage.
- If damaged, remove the strut assembly using a socket set and replace it with a new one.
Inspect Bushings:
- Check all rubber bushings for cracks or deterioration.
- Replace any worn bushings with high-quality replacements.
Check Control Arms:
- Inspect control arms for any signs of wear or damage.
- If damaged, remove the control arm bolts and replace it with a new one.

4. Reassemble and Lower the Vehicle

Reattach the wheel and tighten the lug nuts to the manufacturer's specified torque value.
Carefully lower the vehicle back to the ground.

5. Test Drive

Perform a test drive to ensure the noise has been resolved and the vehicle performs normally.
