If components are damaged, remove the differential cover using a socket set.
- Tools Required: Socket set, screwdriver, pry bar.
Replace worn or damaged gears and bearings as necessary.
- Parts Required: Differential bearing kit, gears (if needed).

4. Clean and Reassemble

Clean the differential housing and cover with a solvent.
Apply a new gasket or sealant to the differential cover.
Reinstall the differential cover and torque the bolts to the manufacturer’s specifications.
- Torque Specification: Refer to the service manual for exact torque values.

5. Refill Differential Fluid

Replace the drain plug and ensure it is tight.
Fill the differential with the recommended fluid type until it reaches the fill level.
- Fluid Type: Refer to the owner’s manual for the specific fluid requirements.

6. Final Checks
