Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Using a jack, lift the rear of the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Shocks/Struts Replacement:
1. Remove the rear wheel to access the suspension components.
2. Unbolt the shock absorber from the top mount and lower mount using a socket set.
3. Replace with new shocks/struts, ensuring proper alignment with mounting holes.
4. Torque the bolts to manufacturer specifications (usually around 40-50 ft-lbs).
Control Arm/Bushing Replacement:
1. Use a wrench to unbolt the control arm from the chassis and wheel hub.
2. Remove the old bushings using a bushing removal tool.
3. Install new bushings and reattach the control arm, torquing bolts to specified torque values.

4. Reassemble and Lower Vehicle

Reinstall the rear wheel and tighten lug nuts to the specified torque (typically 76-85 ft-lbs).
Lower the vehicle from jack stands and remove the jack.

5. Test Drive

Conduct a test drive to ensure the noise has been resolved and the suspension operates smoothly.
