Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if necessary for electrical components.

2. Inspect and Replace Damaged Components

Sub-steps:
1. Raise the vehicle using a hydraulic jack and secure it on jack stands.
2. Remove the wheels to gain access to the suspension components.
3. Inspect struts and shocks for leakage; replace if any signs of wear are present.
4. Check the control arm bushings for cracks or separation; replace if damaged.
5. Tighten any loose bolts or nuts found during the visual inspection.

3. Reassemble and Test

Sub-steps:
1. Reinstall the wheels and torque the wheel bolts to the manufacturer's specifications (typically around 80-100 ft-lbs).
2. Lower the vehicle off the jack stands and remove the jack.
3. Reconnect the battery if disconnected.
4. Take the vehicle for a test drive over bumps to ensure the noise has been resolved.
