Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the differential fluid to cool if the vehicle has been driven recently.

2. Inspect Differential Fluid

Tools Required: Socket set, torque wrench, fluid catch pan.
Remove the differential cover using a socket set.
Inspect the oil for metal particles and burnt smell.
If the fluid is contaminated, drain it completely into a fluid catch pan.

3. Replace Differential Fluid

Clean the differential cover and mating surfaces thoroughly.
Reinstall the differential cover and torque to the manufacturer’s specifications (typically around 20-25 lb-ft).
Fill the differential with the appropriate gear oil (75W-140 or as specified by the manufacturer).

4. Check for Wear on Gears and Bearings

With the differential cover removed, manually rotate the gears and listen for any unusual noises.
Check for excessive play in the ring and pinion gears and bearings.
If wear is detected, consider replacing the affected components.

5. Reassemble and Test Drive

Reattach all components properly and ensure everything is secure.
Test drive the vehicle to confirm the noise has been resolved. Listen carefully for any remaining or new sounds.
