Use wheel chocks to prevent rolling.

2. Raise the Vehicle

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

3. Inspect and Replace Suspension Components

Sway Bar Links:
- Remove the bolts securing the sway bar link to the sway bar and lower control arm using a socket set.
- Replace with new sway bar links and torque to manufacturer specifications (generally around 30-40 ft-lbs).
Struts and Shocks:
- Remove the strut assembly by detaching the upper mounting bolts and lower bolts.
- Inspect for leaks; if leaks are present, replace the strut/shock with a new one.
- Torque new struts to the manufacturer’s specifications.
Bushings and Mounts:
- Remove any components blocking access to the bushings or mounts.
- Replace worn bushings or mounts with new parts, ensuring proper alignment and fit.

4. Reassemble and Lower the Vehicle

Reinstall any components that were removed for access.
Double-check all bolts are secured to the manufacturer’s torque specifications.
Lower the vehicle back to the ground.
