Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is suspected.
Secure the vehicle with jack stands for safety.

3. Remove Wheel (if necessary)

Use a socket set to remove the lug nuts and take off the wheel to gain access to suspension components.

4. Inspect and Replace Components

Sway Bar Links:
- Check for play or damage.
- If damaged, remove the old link using a socket, install the new link, and torque to manufacturer's specifications.
Struts/Shocks:
- Inspect for leaks or damage.
- If necessary, remove the strut by detaching the upper and lower mounting bolts, and replace with a new strut. Torque to specifications.
Bushings:
- Check bushings for cracks or deterioration.
- Replace any worn bushings by removing the component they are attached to, pressing out the old bushing, and installing the new one.

5. Reassemble

Reattach the wheel and torque lug nuts to the manufacturer's specification.
Remove jack stands and lower the vehicle.
