Disconnect the battery to prevent electrical shorts.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the differential drain plug using a socket wrench.
Allow the old fluid to fully drain out.

3. Inspect and Replace Differential Components

Inspect Gears and Bearings:
- Remove the differential cover using a socket set.
- Inspect the gears and bearings for wear or damage.
- If damaged, replace with new components.
Replace Bearings:
- Use a bearing puller to remove old bearings.
- Press new bearings into place, ensuring proper alignment.

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 manufacturer specifications (consult service manual for torque values).

5. Fill with New Differential Fluid

Reinstall the drain plug after ensuring it is clean.
Fill the differential with the specified fluid type (consult owner’s manual for specifications).
Run the vehicle briefly, then check fluid level again and top off if necessary.
