Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Drain Differential Fluid

Locate the differential drain plug.
Place a drain pan beneath the differential and remove the drain plug.
Allow the fluid to completely drain into the pan.

3. Inspect and Replace Components

3.1. Inspect Differential Gears and Bearings

Remove the differential cover by unscrewing the bolts.
Inspect the gears and bearings for wear, scoring, or damage.
If damaged, replace the differential gears and bearings as necessary.

3.2. Replace Differential Fluid

Clean the differential cover and the mating surface.
Install a new gasket or apply silicone sealant if required.
Reattach the differential cover and torque the bolts to the manufacturer’s specifications (typically around 30-40 ft-lbs).
Refill the differential with new fluid as per manufacturer specifications (usually 75W-90 gear oil).

4. Reassemble and Test

Reinstall the drain plug securely after refilling the differential.
Reconnect the battery.
Test drive the vehicle to ensure that the noise has been resolved and listen for any abnormal sounds.
