- Replace with the recommended differential fluid (usually 75W-90 or as specified in the owner's manual).
- Reinstall the drain plug and torque it to the manufacturer's specifications.

3. Remove Differential Cover (if necessary)

Sub-steps:
- Remove the bolts securing the differential cover using a socket set.
- Carefully pry the cover off without damaging the gasket surface.
- Inspect the gears and bearings for wear or damage.

4. Replace Bearings or Gears (if damaged)

Sub-steps:
- Remove the old bearings using a bearing puller.
- Clean the differential housing thoroughly.
- Install new bearings or gears, ensuring proper alignment and lubrication.
- Reinstall the differential cover with a new gasket and torque bolts to specifications.

5. Refill Differential Fluid

Sub-steps:
- Refill the differential with the proper type and amount of fluid through the fill plug.
- Check fluid level and ensure it is at the proper height.
