Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure safety gear is worn, such as gloves and safety glasses.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using a socket set.

3. Inspect Suspension Components

Check the rear shocks/struts for leaks, damage, or wear.
Inspect the bushings and mounts for signs of deterioration.
Examine the springs for cracks or sagging.

4. Replace Damaged Components

If any components are found to be damaged:
- Remove the old component:
  - For shocks, unbolt the top and bottom bolts using the appropriate socket.
- Install new component:
  - Align the new shock or strut and secure it with bolts. Torque to manufacturer specifications (usually around 30-40 lb-ft).
If bushings are worn, use a bushing press to remove and replace them.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle to the ground.
Torque the wheel lug nuts to manufacturer specifications (typically 80-100 lb-ft).
