Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove the Rear Wheel

Use a jack to lift the rear of the vehicle.
Securely place jack stands under the vehicle for safety.
Remove the lug nuts using a socket wrench and take off the rear wheel.

3. Inspect and Replace Shock Absorbers

Check for leaks on the shock absorbers. If found, proceed with replacement.
Remove the mounting bolts securing the shock absorber to the suspension arm and the body of the vehicle.
Install the new shock absorber and torque the bolts to the manufacturer's specifications (typically 30-40 lb-ft).
Repeat for the other side if necessary.

4. Replace Worn Bushings

Inspect the suspension bushings for cracks or deterioration.
Use a bushing removal tool to extract the old bushings.
Install new bushings, ensuring they are correctly seated in the suspension components.

5. Reassemble and Reinstall Wheel

Reinstall the rear wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer’s specifications (typically 75-95 lb-ft).

6. Final Check

Inspect all replaced parts for proper installation.
Ensure all tools are removed from under the vehicle.
