Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, drain pan.
Ensure the vehicle is on a flat surface.
Disconnect the battery if working on electrical components.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the differential drain plug and remove it using a socket.
2. Allow old fluid to drain completely into the drain pan.
3. Inspect the drained fluid for metal shavings or discoloration (indicative of wear).
4. Replace the drain plug and torque to manufacturer specifications.
5. Remove the fill plug and use a funnel to add new differential fluid (ensure it's the correct type as per manufacturer’s specifications).
6. Reinstall the fill plug and torque to manufacturer specifications.

3. Inspect Differential Components

Sub-steps:
1. Remove the differential cover if applicable, following the manufacturer’s procedure.
2. Inspect the ring and pinion gears for wear or pitting.
3. Check bearings and seals for damage.
4. Replace any worn or damaged components as necessary.
5. Reassemble the differential cover with a new gasket if required, and torque to specifications.

4. Test Drive

After repairs, perform a short test drive to ensure the whining noise has been resolved and the vehicle operates smoothly.
