Solution

1. Preparation

Gather tools: jack stands, socket set, torque wrench, fluid pump, and a drain pan.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Drain Differential Fluid

Place the drain pan under the differential.
Remove the differential drain plug using the socket set.
Allow the fluid to drain completely into the pan.

3. Inspect Differential Components

Remove the differential cover by unscrewing the bolts with a socket set.
Inspect the ring and pinion gears for wear or damage.
Check bearings for play or roughness.

4. Replace Worn Components (if necessary)

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

5. Reassemble Differential

Clean the differential cover and apply a new gasket or sealant as per manufacturer specifications.
Reattach the differential cover with the appropriate torque settings (refer to service manual for torque specifications).
Reinstall the drain plug and torque to specifications.

6. Refill Differential Fluid

Use a fluid pump to fill the differential with the recommended fluid type (typically 75W-90 synthetic gear oil).
Fill until the fluid reaches the fill hole.

7. Final Checks

Reconnect the battery.
Start the vehicle and check for leaks around the differential.
Test drive to ensure the whining noise is resolved.
