Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Drain Differential Fluid

Tools Required: Socket set, fluid catch pan.
Place the fluid catch pan under the differential.
Remove the differential drain plug using the socket set.
Allow the fluid to fully drain into the pan.

3. Inspect and Replace Differential Components

Tools Required: Torque wrench, socket set, screwdriver.
Remove the differential cover by unscrewing the bolts with a socket set.
Inspect the gears and bearings for wear or damage.
If worn, replace the differential gears or bearings as necessary, ensuring they are properly aligned and lubricated.
Clean the differential cover and apply new gasket maker or replace the gasket.

4. Refill Differential Fluid

Replace the drain plug and torque it to the manufacturer's specifications (usually around 30 lb-ft).
Refill the differential with the correct type of fluid as specified in the owner's manual (typically 75W-90 gear oil).
Replace the fill plug and torque it to specifications.

5. Reinstall Wheel and Test Drive

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Test drive the vehicle to confirm that the noise has been resolved.
