Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent vehicle movement.

2. Lift the Vehicle

Using a jack, lift the vehicle and secure it with jack stands.
Remove the wheels to access suspension components.

3. Inspect and Replace Components

Inspect Struts/Shocks:
- Check for oil leaks or physical damage.
- If damaged, remove the strut/shock using a socket set and replace it with a new unit, ensuring proper alignment.
- Torque strut mount bolts to manufacturer specifications (usually around 30-50 ft-lbs).
Check Control Arms:
- Inspect bushings for cracking or excessive wear.
- If damaged, remove the control arm and replace it, ensuring to torque the bolts to specification (often 60-80 ft-lbs).
Examine Sway Bar Links:
- Check for any looseness or wear in the sway bar links.
- Replace if necessary; torque the sway bar link bolts to around 40-50 ft-lbs.

4. Reassemble

Reinstall the wheels and lower the vehicle.
Ensure all tools are removed from under the vehicle.

5. Final Inspection

Double-check all new components for proper installation and torque specifications.
Test drive the vehicle to confirm the noise has been resolved.
