Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for added safety.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle as needed.
Secure with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Check for leaks or damage.
- If defective, remove the strut assembly by unbolting it from the top mount and lower control arm.
- Replace with new struts and secure, following manufacturer torque specifications.
Check Control Arms:
- Inspect control arm bushings for deterioration.
- If damaged, remove the control arm by unbolting it from the chassis and the wheel hub.
- Replace with a new control arm and torque bolts to specifications.
Examine Sway Bar Links:
- Check for play in sway bar links.
- If worn, remove and replace them following the same securing process.

4. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Test drive the vehicle over bumps to ensure the noise is resolved.
