Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, fluid catch pan.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Drain Differential Fluid

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

3. Inspect Differential Components

Remove the differential cover (if applicable) or access panel using a socket set.
Inspect the gears, bearings, and any visible components for wear or damage.
Rotate the differential gears to check for smooth operation without binding or excessive noise.

4. Replace Worn Components

If any gears or bearings are damaged, replace them with OEM parts.
Ensure all components are adequately cleaned before reassembly.

5. Refill Differential Fluid

Replace the differential cover or access panel, ensuring a proper seal.
Refill the differential with the manufacturer-recommended fluid type (usually SAE 75W-90 gear oil).
Torque the fill and drain plugs to the manufacturer specifications.

6. Test Drive

Lower the vehicle to the ground and perform a test drive to verify that the whining noise has been resolved.
