Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Remove Rear Wheel

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the rear wheel.

3. Inspect and Replace Components

Shock Absorbers:
- Remove the bolts securing the shock absorber to the upper mount and lower control arm.
- Replace with new shock absorbers, tightening bolts to manufacturer specifications (typically 50-70 ft-lbs).
Control Arms and Bushings:
- Detach the control arm by removing the bolts connecting it to the chassis and the wheel hub.
- Inspect bushings for wear; replace if cracked or worn.
- Install the new control arm and bushings, torque bolts to manufacturer specifications.

4. Reassemble

Reinstall the rear wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specification (usually around 100 ft-lbs).

5. Final Inspection

Reconnect the battery.
Test drive the vehicle to ensure that the noise has been resolved and that the suspension feels stable.
