Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack, jack stands, pry bar, rubber mallet
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle and securely place jack stands underneath the vehicle for safety.

3. Inspect and Replace Components

Control Arms and Bushings:
- Inspect control arms and bushings for wear or damage.
- If worn, remove the bolts securing the control arm using a socket set.
- Use a pry bar to remove the old bushing and install the new bushing.
- Reinstall the control arm and torque bolts to manufacturer specifications (usually around 80-90 ft-lbs).
Shock Absorbers:
- Check shock absorbers for any signs of leakage or damage.
- If replacement is needed, remove the bolts securing the shock absorber at both the top and bottom.
- Install the new shock absorber and torque bolts to manufacturer specifications (typically around 35-50 ft-lbs).
Springs:
- Inspect rear springs for cracks or breakage.
- If replacing, compress the spring using a spring compressor, remove it, and install a new spring.

4. Reassembly

Recheck all bolts for tightness and ensure everything is secure.
Lower the vehicle back to the ground.
