Solution

1. Preparation

Tools Required: Floor jack, jack stands, wheel chocks, socket set, torque wrench, stethoscope.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect Differential Fluid

Remove the fill plug from the differential housing.
Check fluid level; it should be at the bottom of the fill hole.
If necessary, drain the fluid into a clean container to inspect for metal shavings or debris.

3. Replace Differential Fluid (if contaminated)

Parts Required: New differential fluid (check owner’s manual for specifications).
Refill the differential with the appropriate fluid until it reaches the proper level.
Replace the fill plug and torque to manufacturer specifications.

4. Inspect Rear Axle Components

Raise the rear of the vehicle using a floor jack and secure with jack stands.
Remove the rear wheels to access brake components.
Inspect the wheel bearings, axle shafts, and differential for any signs of wear or damage.
Replace any worn or damaged components as necessary.

5. Test Drive

Lower the vehicle and conduct a test drive to verify that the noise has been resolved.
Pay attention to the conditions under which the noise occurs to ensure the issue is fully addressed.
