Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal if working on electrical components.

2. Inspect and Secure Cargo Area

Remove all items from the rear cargo area.
Check for any loose trim pieces or covers; re-secure them as needed.
Use a flashlight to inspect for any visible damage or loose connections.

3. Examine Rear Suspension

Use a jack to lift the rear of the vehicle and support it with jack stands.
Inspect the shock absorbers for leaks or damage.
Check the bushings and mounting points for wear; replace if necessary.
Torque specifications for mounting bolts should be adhered to (typically around 30-50 ft-lbs, but refer to the service manual for specifics).

4. Inspect Exhaust System

Visually check the exhaust system for any loose brackets or broken hangers.
Tighten any loose bolts or replace broken hangers as needed.
If noise persists, check for exhaust leaks by spraying soapy water at the joints and looking for bubbles.

5. Check Rear Wheel Area

Remove the rear wheels using a lug wrench.
Inspect lug nuts for tightness (re-torque to manufacturer specifications, usually around 76-80 ft-lbs).
Check brake components for any signs of wear or loose hardware.

6. Test Drive

After reassembling all components, take the vehicle for a test drive to ensure the noise has been eliminated.
