Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Gather necessary tools and parts.
Wear safety gear including gloves and goggles.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Remove the wheels if necessary to access suspension components.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- Remove the bolts securing the strut to the knuckle and the top mount.
- Replace with new shock absorbers/struts.
- Torque bolts to manufacturer specifications (typically around 70-80 ft-lbs for lower bolts, check specific torque for top mount).
Sway Bar Links and Bushings:
- Unbolt the sway bar link from the sway bar and control arm.
- Replace with new sway bar links and bushings.
- Torque to specification (usually around 30-40 ft-lbs).

4. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Start the vehicle and test drive over bumps to ensure the noise is resolved.
