Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.
Gather the necessary tools (socket set, jack stands, torque wrench).

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 source of the noise).

3. Inspect and Replace Components

A. Shock Absorbers/Struts

Check for any leaks or damage.
If defective, remove the bolts securing the shock/strut assembly.
Replace with new units, ensuring proper orientation, and torque to manufacturer specifications.

B. Control Arms and Bushings

Inspect control arms for wear; replace if necessary.
For bushings, use a bushing removal tool to replace worn bushings.
Reinstall control arms and torque bolts according to specifications.

C. Sway Bar and Links

Inspect sway bar links for wear or looseness.
Replace any damaged links by removing the bolts and installing new ones; torque to specifications.

4. Reassemble and Lower Vehicle

Reinstall the wheels and torque the lug nuts in a star pattern.
Lower the vehicle back to the ground and remove jack stands.
