Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, differential oil pump, OBD-II scanner.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues during the repair.

2. Drain and Replace Differential Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the differential drain plug and place a drain pan underneath.
3. Remove the drain plug and allow the old fluid to completely drain.
4. Inspect the fluid for metal particles or debris; replace if necessary.
5. Reinstall the drain plug with a new washer and torque to manufacturer's specifications (typically around 30 lb-ft).

3. Inspect and Replace Differential Seals

Sub-steps:
1. Remove the differential cover (if applicable) to access the internal components.
2. Inspect the differential seals for wear or damage.
3. Use a seal puller to remove the old seals.
4. Clean the sealing surfaces thoroughly before installing new seals.
5. Apply a small amount of differential fluid to the new seals and install them, ensuring they are seated properly.

4. Reassemble and Refill Differential

Sub-steps:
1. If the differential cover was removed, apply a new gasket or sealant and reinstall the cover.
2. Refill the differential with the recommended fluid type (typically 75W-90 gear oil) using a differential oil pump.
3. Fill until the fluid reaches the fill hole level.
4. Reinstall the fill plug and torque to specifications.

5. Test Drive

Conduct a short test drive to assess the noise. Listen for any abnormal sounds and check the performance of the vehicle.
