Solution

1. Fluid Replacement

Sub-steps:
- Raise the vehicle securely using jack stands.
- Remove the differential fill plug and drain plug to let old fluid escape.
- Inspect the old fluid for metal particles or burning smell.
- Replace with manufacturer-recommended differential fluid (typically 75W-90 or equivalent).
- Torque the drain plug to the manufacturer's specifications (usually around 30-40 ft-lbs).
- Reinstall the fill plug.

2. Bearing and Gears Inspection

Sub-steps:
- If noise persists, remove the differential cover to inspect the gears and bearings.
- Check for wear patterns on the gears, and look for pitting or scoring.
- Spin the differential to listen for grinding or roughness.
- If damage is found, remove the differential assembly for bearing replacement.

3. Bearing Replacement

Sub-steps:
- Use a bearing puller to remove the old bearings from the differential housing.
- Clean the housing thoroughly and lubricate the new bearings with differential fluid.
- Press new bearings into the differential housing using a bearing press.
- Reassemble the differential with new seals and gaskets, ensuring a proper fit.
