Solution

1. Preparation

Gather tools and materials:
- Socket set
- Torque wrench
- Oil catch pan
- Differential fluid (as per manufacturer specifications)
- Clean rags
Ensure the vehicle is on a level surface and securely elevated using jack stands.

2. Drain Differential Fluid

Place an oil catch pan under the differential drain plug.
Remove the drain plug using a socket wrench and allow the fluid to completely drain.
Inspect the fluid for metal shavings or signs of contamination.

3. Inspect Components

Examine the differential gears and bearings through the fill hole.
Look for signs of wear, damage, or excessive play in the gears.
If components are damaged, proceed to replace the affected parts.

4. Clean and Refill Differential

Clean the drain plug and apply a new gasket if necessary.
Reinstall the drain plug and torque it to the manufacturer’s specifications (usually around 30-40 Nm).
Using a funnel, refill the differential with the appropriate fluid until it reaches the fill hole (typically around 1-2 quarts).

5. Test Drive

Lower the vehicle and remove jack stands.
Take the vehicle for a test drive to ensure that the whining noise has diminished or stopped.
Recheck for leaks after the test drive.
