Solution

1. Preparation

Gather tools: jack stands, socket set, torque wrench, fluid pump, and a differential fluid tester.
Ensure the vehicle is parked on a level surface and securely lifted.

2. Check and Replace Rear Differential Fluid

Sub-steps:
1. Remove the rear differential fill plug using a socket wrench.
2. Check fluid level; it should be at the bottom of the fill hole.
3. If low, remove the drain plug and allow old fluid to drain completely.
4. Inspect the old fluid for metal shavings or a burnt smell.
5. Reinstall the drain plug and refill with the manufacturer-recommended differential fluid (typically 75W-90).
6. Torque the fill plug to the manufacturer’s specifications.

3. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Remove the rear wheel by loosening lug nuts and using a jack to lift the vehicle.
2. Inspect the hub assembly for any signs of damage or excessive play.
3. If play is detected, disassemble the hub assembly by removing the caliper and rotor.
4. Replace the wheel bearing using a bearing press and install a new bearing.
5. Reassemble the hub, rotor, and caliper, ensuring all bolts are torqued to specification.

4. Test Drive

Conduct a test drive to ensure the whining noise has ceased and that the vehicle operates smoothly.
