Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Use wheel chocks to prevent any movement.

2. Raise the Vehicle

Using a hydraulic jack, lift the rear of the vehicle and secure it on jack stands.
Remove the rear wheels using a lug wrench.

3. Inspect and Replace Components

Shocks/Struts Replacement
- Disconnect the shock absorber from the lower mounting point using a socket set.
- Remove the upper mount of the shock by accessing the bolts inside the trunk area.
- Install the new shock absorber by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications (typically around 30-50 ft-lbs).
Sway Bar Links and Bushings Replacement
- Remove the sway bar link by unbolting it from the sway bar and the lower control arm.
- Inspect the bushings for wear; if damaged, replace them with new ones.
- Reinstall the new sway bar link, ensuring proper torque (usually around 30 ft-lbs).

4. Reassemble and Lower the Vehicle

Reinstall the rear wheels and hand-tighten the lug nuts.
Carefully lower the vehicle back to the ground using the hydraulic jack.
Torque the lug nuts to the manufacturer’s specifications (typically 100-120 ft-lbs).

5. Test Drive

Take the vehicle for a test drive to ensure the noise has been resolved and check for any unusual handling characteristics.
