Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Drain Differential Fluid

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

3. Inspect and Replace Components

Inspect Bearings:
- Remove the rear differential cover using the appropriate socket.
- Check the condition of the bearings and gears for signs of wear or damage.
- If worn, replace the bearings with OEM parts.
Replace Gaskets and Seals:
- Remove old gaskets and clean the mating surfaces.
- Install new gaskets and seals to prevent leaks.

4. Refill Differential Fluid

Replace the drain plug and torque it to the manufacturer's specification (typically around 30 lb-ft).
Fill the differential with the recommended fluid (typically 75W-90 GL-5 gear oil) through the fill plug until it reaches the proper level.

5. Reassemble and Test

Reinstall the differential cover and torque the bolts to manufacturer specifications.
Reconnect the battery.
Perform a test drive to ensure the noise has been eliminated.
