Solution

1. Preparation

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

2. Raise the Vehicle

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

3. Inspect and Replace Components

A. Shock Absorbers

Remove the old shock absorbers:
- Unscrew the nuts at the top of the shock mounts and the bolts at the bottom using a socket set.
- Pull the shock absorber out of its mounting location.
Install new shock absorbers:
- Position the new shock absorber in place.
- Tighten the top mount nuts to the manufacturer's specified torque (typically around 30 Nm or as specified).
- Secure the bottom bolts, ensuring they are torqued to the specified value (usually around 50 Nm).

B. Control Arm Bushings

Remove the control arms if bushings are worn:
- Unscrew the bolts securing the control arms to the subframe and the wheel hub.
- Replace the bushings using a bushing press or appropriate tool.
Reinstall control arms:
- Position the control arm and secure with bolts, torquing to specifications.

4. Reassemble and Lower the Vehicle

Ensure all components are secured and double-check for proper installation.
Lower the vehicle from the jack stands using the jack.
