Solution

1. Preparation

Tools Required:
- Floor jack
- Jack stands
- Torque wrench
- Mechanic’s stethoscope
- Socket set
Safety Warnings:
- Always ensure the vehicle is on a flat surface and secured with jack stands before working underneath.

2. Remove Rear Wheel

Loosen the lug nuts on the rear wheel while the vehicle is on the ground.
Use the floor jack to lift the rear of the vehicle.
Secure the vehicle with jack stands.
Remove the lug nuts completely and take off the rear wheel.

3. Inspect and Replace Components

Shock Absorbers:
- Inspect for leakage or wear.
- If damaged, remove the shock absorber by unbolting it from the upper and lower mount.
- Install the new shock absorber and tighten to manufacturer specifications (typically around 30-40 ft-lbs).
Bushings:
- Check the bushings for cracks or wear. If necessary, use a bushing removal tool to extract old bushings.
- Install new bushings and ensure they are seated properly.
Joints:
- Inspect control arm joints for play. If excessive, replace affected parts by removing bolts and installing new joints.

4. Reassemble

Reinstall the rear wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended specification (typically around 100-110 ft-lbs).
Remove jack stands and lower the vehicle completely.
