Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Raise the Vehicle

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

3. Inspect and Replace Components

Inspect Shock Absorbers:
- Check for leaks or physical damage.
- If damaged, remove the bolts securing the shock absorber and replace it with a new one.
- Ensure to torque the bolts to the manufacturer’s specifications (typically around 40-50 ft-lbs).
Inspect Springs:
- If springs are broken or sagging, remove the suspension assembly by unbolting the lower control arm and the top mount.
- Replace with new springs and reassemble, ensuring proper alignment.
Check Bushings:
- Inspect bushings for cracks or wear.
- If necessary, press out the old bushings and install new ones using a bushing tool.

4. Reassemble Suspension

Reinstall all components in reverse order, ensuring all bolts are torqued correctly.
Reattach the wheel and lower the vehicle back to the ground.
