Solution

1. Preparation

Gather tools: jack, jack stands, wrench set, differential fluid, socket set, torque wrench, and a stethoscope.
Ensure the vehicle is on a level surface and secure it with jack stands after raising it.

2. Inspect and Replace Differential Fluid

Remove the differential drain plug using a socket wrench.
Allow old fluid to drain completely into a suitable container.
Inspect the old fluid for metallic shavings or debris, indicating internal wear.
Replace the drain plug and tighten to manufacturer specifications.
Remove the fill plug and refill the differential with new fluid until it reaches the fill hole level.
Replace the fill plug and tighten securely.

3. Inspect Differential Gears and Bearings

Remove the rear differential cover if the grinding persists after fluid change.
Inspect the gears for signs of wear or damage, such as pitting or scoring.
Check the bearings for play or roughness by turning them by hand.
If any components are damaged, replace them accordingly.

4. Reassemble and Torque

If the differential cover was removed, clean the mating surfaces and apply a new gasket or sealant.
Reinstall the differential cover and torque the bolts to the manufacturer's specifications.
