Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels for better access to suspension components.

3. Inspect and Replace Components

Inspect Shock Absorbers:
- Check for leaks or physical damage.
- If defective, remove the shock absorber by unbolting it from the top and bottom mounts.
- Replace with a new shock absorber, ensuring proper alignment and torque specifications are followed (typically 40-50 ft-lbs).
Check Control Arm Bushings:
- Inspect bushings for cracks or excessive wear.
- If necessary, remove the control arm by unbolting it from the chassis and wheel hub.
- Replace bushings and reinstall the control arm, tightening to manufacturer specifications.

4. Reassemble and Lower Vehicle

Reattach the wheels and lower the vehicle back to the ground.
Recheck the torque on all suspension components.
