Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Drain pan
- Differential fluid pump
Safety Warnings:
- Use proper lifting techniques; ensure the vehicle is securely supported before working underneath.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the drain plug using a socket wrench and allow the fluid to completely drain.
Inspect the fluid for metal shavings or debris that may indicate internal wear.

3. Inspect and Replace Components

Remove the differential cover if necessary to inspect the internal gears and bearings.
Check for signs of wear on gears and bearings; replace any worn components.
- Tools Required:
  - Gasket scraper
  - New gasket or sealant
If bearings are worn, use a bearing puller to remove them and install new bearings by pressing them onto the differential.

4. Reassemble and Fill Differential

Clean the differential cover and mating surface. Apply a new gasket or sealant as required.
Reinstall the differential cover and tighten bolts to the manufacturer's torque specifications (consult service manual for specific torque values).
Using a differential fluid pump, refill the differential with manufacturer-recommended fluid to the proper level.

5. Test Drive

Lower the vehicle and remove wheel chocks.
Take the vehicle for a test drive to verify that the whining noise has been eliminated and that the differential operates smoothly.
