Sub-steps:
1. Reinstall the differential cover with a new gasket or sealant as needed.
2. Fill the differential with the manufacturer-recommended fluid using a fluid pump.
3. Ensure the fluid level is filled to the manufacturer’s specifications.

4. Inspect and Replace Damaged Components

Sub-steps:
1. If the noise persists, remove the axles by disconnecting them from the differential.
2. Check the axle bearings for damage; replace if any wear is found.
3. Inspect the differential ring and pinion gears for signs of wear or chips.
4. Replace any damaged components using a torque wrench to ensure proper specifications during reassembly.

5. Test Drive

After reassembly, lower the vehicle and perform a test drive to verify the repair.
Monitor for any noise or abnormal behavior during different driving conditions.
