- Clean the differential cover and housing surfaces.
- Apply a new gasket or RTV sealant to the differential cover.
- Reattach the differential cover and torque bolts to manufacturer specifications.
- Use a fluid pump to fill the differential with new fluid until it reaches the fill line.

4. Inspect and Replace Components

Tools Required: Socket set, pry bar, torque wrench
- Remove the rear axle shafts if necessary to access internal components.
- Inspect the ring and pinion gears for wear or damage.
- Check the differential bearings for play; replace if necessary.
- Reassemble by reversing the disassembly process, ensuring all components are torqued to specifications.

5. Test Drive

After repairs, perform a short test drive to ensure the noise has been resolved.
Monitor for any unusual sounds or vibrations during the drive.
