Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle.
Secure the vehicle on jack stands for safety.

3. Inspect and Replace Worn Components

Shocks/Struts:
- Detach the lower shock mounting bolt using a socket set.
- Remove the upper mounting bolts from the chassis.
- Replace with new shocks/struts and torque bolts to manufacturer specifications (typically around 30-40 ft-lbs).
Bushings:
- Remove control arm bolts and sway bar links if bushings are worn.
- Use a bushing removal tool to replace any damaged bushings.
- Reassemble and torque to specifications.

4. Reassemble Suspension Components

Reattach any components that were removed for the inspection.
Ensure all bolts and nuts are tightened to the specified torque values.

5. Lower the Vehicle

Carefully remove jack stands and lower the vehicle with the jack.
Recheck all components for proper installation and tightness.
