Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Damaged Suspension Components

Lift the Vehicle:
- Use a hydraulic jack to lift the front or rear of the vehicle as needed.
- Secure it with jack stands for safety.
Remove Wheel:
- Use a lug wrench to remove the wheel corresponding to the side with the identified noise.
Inspect Struts and Shocks:
- Check for oil leaks on the struts or shocks; if leaking, they need to be replaced.
- Inspect the bushings for wear or deterioration.
Replace Components if Necessary:
- If struts or shocks are damaged, unbolt them from the mounts and replace with new parts.
- Torque the bolts to manufacturer specifications (typically around 40-50 ft-lbs for strut mounts).

3. Reassemble

Reattach Wheel:
- Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the Vehicle:
- Carefully remove the jack stands and lower the vehicle back to the ground.
Torque Lug Nuts:
- Use a torque wrench to fully tighten the lug nuts to the recommended specification (usually 75-80 ft-lbs).
