Solution

1. Preparation

Tools Required: Socket set, jack stands, wheel chocks, drain pan
Safety Warning: Ensure the vehicle is on a flat surface and secure with wheel chocks before lifting.

2. Drain Differential Fluid

Place the drain pan under the differential.
Remove the drain plug using the appropriate socket and allow the fluid to completely drain.
Inspect the fluid for metal shavings or debris, indicating potential gear wear.

3. Inspect and Replace Components

Inspect Gears: Remove the differential cover if metal shavings are present. Check for pitting or wear on the gears.
Replace Bearings: If wear is noted, replace the differential bearings and races.
Check Seals: Inspect and replace any worn seals to prevent fluid leaks.

4. Refill Differential Fluid

Replace the differential cover using a new gasket or sealant as required.
Tighten the cover bolts to the manufacturer’s specified torque.
Refill the differential with the recommended type and quantity of fluid, typically a gear oil of SAE 75W-90.

5. Test Drive and Monitor

Lower the vehicle and remove wheel chocks.
Test drive the vehicle to ensure the whine has been resolved and monitor for any additional noises.
