Solution

1. Preparation

Gather tools: socket set, torque wrench, jack, jack stands, and a flashlight.
Park the vehicle on a level surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Secure the vehicle on jack stands to ensure safety during inspection.

3. Inspect Suspension Components

Visually inspect the struts and shocks for any signs of leakage or damage.
Check the bushings in control arms for wear; replace if cracked or deteriorated.
Examine sway bar links for looseness or damage; replace if necessary.

4. Examine Exhaust System

Inspect the exhaust hangers and mounts for wear; replace any that are damaged or missing.
Make sure the exhaust system is properly secured and does not contact the undercarriage.

5. Check Tires and Fasteners

Inspect all tires for uneven wear and ensure they are properly inflated.
Tighten all relevant suspension bolts to manufacturer specifications using a torque wrench.
