Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, jack and jack stands, lubricant, and replacement parts if needed.
Park the vehicle on a level surface and set the parking brake.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on where the noise originates.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Inspect and Replace Components

A. Shock Absorbers/Struts

Remove the wheel to access the suspension.
Unbolt the top and bottom mounts of the shock absorber or strut.
Replace with a new shock absorber or strut if damaged. Torque to manufacturer specifications.

B. Sway Bar Links and Bushings

Locate the sway bar links and inspect for damage.
Unbolt the links and replace them if worn. Ensure bushings are also replaced if cracked or dry-rotted.

C. Control Arm Bushings

Check the control arm bushings for play.
If worn, unbolt the control arm and replace the bushings. Reassemble and torque to specifications.

4. Reassemble and Lower Vehicle

Reattach the wheel and tighten lug nuts to the specified torque.
Lower the vehicle back to the ground and remove jack stands.
