Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to prevent electrical issues during the repair.

2. Drain Differential Fluid

Locate the differential drain plug.
Use a socket wrench to remove the drain plug and allow fluid to fully drain into a suitable container.
Inspect the drained fluid for metal shavings or debris, indicating internal wear.

3. Inspect Differential Components

Remove the differential cover using a socket set.
Visually inspect the gears, bearings, and seals for wear or damage.
If any damaged components are found, note them for replacement.

4. Replace Seals and Bearings (if necessary)

Remove and replace any worn seals with new ones, ensuring proper seating.
If bearings show signs of wear, remove them using a bearing puller and install new bearings.
Lubricate new bearings with differential fluid before installation.

5. Reassemble and Fill Differential

Reinstall the differential cover, ensuring the gasket is properly aligned.
Torque the cover bolts to the manufacturer's specified value (typically around 30-40 ft-lbs).
Fill the differential with the appropriate type and amount of fluid as specified in the owner’s manual.

6. Final Checks

Reconnect the battery.
Start the vehicle and allow it to idle, listening for any unusual noises.
Take the vehicle for a test drive to ensure the noise has been resolved.
