Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working on electrical components.

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 into the pan.
Inspect the old fluid for metal shavings or debris.

3. Inspect Differential Components

Remove the differential cover by unscrewing the bolts with a socket set.
Examine the gears, bearings, and other internal components for wear or damage.
Replace any damaged components as necessary.

4. Clean and Reassemble

Clean the differential housing and cover with a suitable solvent to remove old gasket material.
Install a new gasket or apply silicone sealant to the differential cover.
Reattach the differential cover and torque the bolts to the manufacturer's specifications (usually around 30-40 lb-ft, but refer to service manual for specifics).

5. Refill Differential Fluid

Replace the drain plug securely.
Fill the differential with the appropriate fluid type (consult owner's manual, typically a high-quality gear oil).
Check the fluid level with the fill plug removed; ensure it reaches the fill hole.

6. Test Drive

Reconnect the battery.
Take the vehicle for a test drive to ensure the grinding noise is resolved and check for any leaks.
