Solution

1. Preparation

Gather all required tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Fluid Inspection and Replacement

Check Fluid Level:
1. Locate the rear differential fill plug and remove it.
2. Use a fluid level gauge to check if the fluid is at the proper level.
Replace Fluid if Necessary:
1. If fluid is low or dirty, drain the old differential fluid using a drain pan.
2. Replace with manufacturer-recommended differential fluid (e.g., 75W-90 gear oil).
3. Reinstall the fill plug and torque to the manufacturer specification.

3. Driveshaft and Differential Inspection

Inspect Driveshaft:
1. Remove the driveshaft by loosening the bolts connecting it to the rear differential.
2. Inspect the universal joints for play or damage; replace if necessary.
Examine Rear Differential:
1. Check the rear differential housing for cracks or damage.
2. Inspect bearings and gears inside the differential for wear; replace any damaged components.

4. Test Drive

Reconnect the battery and take the vehicle for a test drive to confirm that the whining noise has been resolved.
