Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Drivetrain Components

Inspect Drive Belts and Pulleys
- Remove any covers blocking access to the belts.
- Check for wear, cracks, or looseness in the belts.
- If damaged, replace with OEM specifications.
Check Transmission Fluid
- Locate the transmission dipstick; remove and inspect the fluid level and condition.
- If low or dirty, drain the transmission and replace it with the manufacturer-recommended fluid.
Inspect Differential Fluid
- Locate the differential fill plug; check fluid level.
- If low, drain and refill with appropriate differential gear oil.

3. Address Wheel Bearings and Hubs

Inspect Wheel Bearings
- Lift the vehicle and spin each wheel to check for roughness or play.
- If noise or play is found, remove the wheel hub assembly and replace the bearings.

4. Reassemble and Test

Reinstall any components or covers removed during inspection.
Reconnect the battery.
Start the vehicle and perform a test drive to ensure the whining noise is resolved.
