Solution

1. Preparation

Gather tools and necessary parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues while working.

2. Drain Differential Fluid

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

3. Inspect and Replace Bearings/Gears

Remove the differential cover by unscrewing the bolts with a socket set.
Inspect the gears and bearings for wear or damage.
If damaged, replace the differential gears and/or bearings:
- Remove the old bearings using a bearing puller.
- Install new bearings with a press tool, ensuring they are seated correctly.
- Replace any damaged gears as necessary, following the manufacturer’s specifications for assembly.

4. Reassemble Differential

Clean the differential housing and cover surfaces.
Apply a new gasket or sealant as recommended by the manufacturer.
Reattach the differential cover and tighten bolts to the specified torque values (usually around 30-40 lb-ft, but check the service manual).

5. Refill with Differential Fluid

Replace the drain plug and torque it to manufacturer specifications.
Fill the differential with the appropriate type and amount of fluid (usually around 1.5-2 quarts of 75W-90 gear oil).
Check the fluid level using the fill plug; it should be level with the bottom of the fill hole.

6. Final Checks

Reconnect the battery.
Start the vehicle and let it run, listening for any abnormal noises.
Test drive the vehicle to ensure the grinding noise is eliminated.
