Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the drain plug and allow the old fluid to completely drain out.
Inspect the fluid for metal shavings or discoloration, which indicates internal wear.

3. Inspect and Replace Components

Remove the differential cover by unscrewing the bolts securing it.
Inspect the gears and bearings for signs of wear or damage.
- Tools Required: Socket set, torque wrench.
If damaged, replace the gears or bearings as necessary.
Clean the differential housing and cover with a solvent.

4. Reassemble and Refill

Replace the differential cover with a new gasket or sealant.
Torque the bolts to the manufacturer's specification.
Refill the differential with the correct type of fluid as specified in the vehicle’s manual.
- Fluid Type: Typically, 75W-90 gear oil, but verify with the owner's manual.

5. Final Checks

Reconnect the battery.
Lower the vehicle and ensure everything is secure.
Check for leaks after refilling the fluid.
