Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels, depending on the noise location.

3. Inspect and Replace Components

Struts/Shocks:
- Remove the strut assembly by disconnecting the top mount bolts and lower strut bolts.
- Inspect for leaks or damage; replace if necessary.
- Reinstall the new strut and torque bolts to manufacturer specifications (usually around 30-50 ft-lbs).
Sway Bar Links:
- If damaged, remove the sway bar link bolts with a socket set and replace with new links.
- Torque the bolts to specified values (typically 25-40 ft-lbs).
Bushings:
- Check control arm and sway bar bushings for wear; replace if cracked or dry-rotted.
- Use a bushing press or appropriate tools to remove and install bushings.

4. Reassemble and Lower the Vehicle

Reinstall wheels and torque lug nuts to manufacturer specifications (usually 80-100 ft-lbs).
Lower the vehicle from the jack stands and remove wheel chocks.
