Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, and torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down before starting work.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove Rear Wheels:
- Use a lug wrench to remove the lug nuts and take off the rear wheels.
Inspect Shocks and Springs:
- Check for leaks or damage on the rear shocks. If leaking or damaged, remove the bolts securing the shocks to the mount and replace with new shocks.
- Inspect the coil springs for cracks or breaks; replace if necessary.
Check Bushings and Mounts:
- Inspect all control arm bushings for wear. Replace any that are cracked or deteriorated.
Reassemble Components:
- Reattach shocks and any other components in reverse order, ensuring all bolts are tightened to manufacturer specifications.

3. Inspect Wheel Bearings

Check Bearing Play:
- After lifting the vehicle, grab the rear wheel and shake it side to side. Any play indicates a worn bearing.
Replace Wheel Bearings if Necessary:
- Remove the hub assembly if bearings are worn, and replace them according to manufacturer specifications.

4. Reinstall Rear Wheels

Put the rear wheels back on and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the recommended specifications.
