Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels as necessary for better access to suspension components.

3. Inspect and Replace Damaged Components

Shocks/Struts:
- Remove the upper mounting bolts and lower bolts from the strut assembly.
- Replace with new struts or shocks if leaking or damaged.
- Torque new strut bolts to manufacturer specifications (usually around 85-100 ft-lbs).
Bushings and Mounts:
- Remove damaged bushings using a bushing removal tool.
- Install new bushings, ensuring proper alignment.
Sway Bar Links:
- Detach the sway bar links by removing the nuts from both ends.
- Install new sway bar links and torque to specifications (typically 30-45 ft-lbs).

4. Reassemble

Reinstall wheels and lower the vehicle.
Tighten all lug nuts to the manufacturer's specifications (usually 76-85 ft-lbs).

5. Test Drive

Conduct a test drive to ensure that the suspension noise has been resolved.
Listen for any remaining noise and check for proper handling.
