Solution

1. Preparation

Gather tools (socket set, torque wrench, jack stands, wheel chocks).
Ensure the vehicle is on a flat surface and secure.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle.
Place jack stands under the rear subframe for added safety.
Remove the rear wheels to access the suspension components.

3. Inspect and Replace Shock Absorbers

Inspect the Shock Absorbers:
- Check for signs of leakage or physical damage.
Remove the Shock Absorbers:
- Remove any retaining bolts securing the upper and lower ends of the shock absorber.
- Carefully detach the shock absorber from its mounts.
Install New Shock Absorbers:
- Position the new shock absorber in place.
- Secure it with bolts, tightening them to the manufacturer’s torque specifications.

4. Replace Worn Bushings (if applicable)

Remove Control Arms:
- If bushings are worn, remove the control arm from the vehicle.
- Use a bushing removal tool to extract old bushings.
Install New Bushings:
- Press new bushings into the control arm.
- Reattach the control arm to the vehicle, securing with the appropriate torque.

5. Reassemble the Rear Suspension

Reinstall the rear wheels and lower the vehicle off the jack stands.
Torque the wheel lug nuts to the manufacturer’s specification.

6. Final Inspection

Double-check all components and fasteners for tightness.
Ensure all tools are removed from the area before starting the vehicle.
