Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and securely lifted.
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 out and inspect for metal shavings.

3. Inspect Differential Components

Remove the differential cover bolts using a ratchet and socket.
Carefully remove the differential cover and inspect the gears, bearings, and shims for wear or damage.
Check the condition of the ring and pinion gears for scoring or pitting.

4. Replace Worn Components

If any components are damaged (bearings, gears), replace them with OEM parts.
Clean the differential housing and cover surfaces thoroughly.
Apply a new gasket or sealant to the differential cover.

5. Refill Differential with Fluid

Reinstall the differential cover and secure it with the bolts, ensuring they are torqued to the manufacturer's specifications (typically around 20-25 ft-lbs).
Refill the differential with the appropriate fluid type (usually 75W-90 gear oil) through the fill plug until it reaches the proper level.

6. Final Checks

Reconnect the battery.
Ensure all tools are removed from under the vehicle.
Test drive the vehicle to confirm that the noise has been resolved.
