Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the vehicle to cool down if it has been running.

2. Drain Differential Fluid

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

3. Inspect and Replace Differential Components

Tools Required: Torque wrench, socket set, replacement parts
Inspect the differential gears and bearings for wear.
If damaged, remove the differential cover by unbolting it.
Replace any worn gears, bearings, or seals as necessary.
Reassemble the differential cover and torque to the manufacturer’s specifications.

4. Fill Differential with New Fluid

Tools Required: Funnel
Replace the drain plug securely.
Using a funnel, fill the differential with the appropriate type and amount of fluid specified in the owner's manual.
Replace any fill plug and ensure it is tightened properly.

5. Recheck for Leaks

Start the vehicle and let it idle while checking for any fluid leaks around the differential.
If no leaks are detected, proceed to test drive the vehicle to ensure the noise has been resolved.
