Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise it using jack stands.
Disconnect the battery to ensure safety during repairs.

2. Check and Replace Differential Fluid

Remove the fill plug on the differential using a socket wrench.
Inspect the fluid for metal shavings or discoloration. If contaminated, proceed to replace it.
Drain the old fluid by removing the drain plug.
Allow the differential to fully drain and clean any metal debris from the drain pan.
Replace the drain plug with a new gasket and torque it to manufacturer specifications.
Refill the differential with the appropriate type and amount of new fluid (refer to the owner's manual for specifications).

3. Inspect and Replace Differential Components

If noise persists, remove the differential cover to inspect internal gears.
Check for wear on the ring and pinion gears and look for cracks or pitting.
Inspect bearings for play or damage; replace any worn components.
Reassemble the differential cover with a new gasket and torque bolts to specifications.

4. Reassemble and Test

Reconnect the battery.
Lower the vehicle and perform a test drive to ensure the noise has been resolved.
Monitor for any signs of leaks or further noise after the test.
