Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, jack and jack stands.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect Drive Unit

Sub-steps:
- Remove any protective covers over the drive unit if necessary.
- Check for loose or damaged wiring connected to the electric motor.
- Inspect the drive unit for any signs of oil leaks or component failure.
- Tighten any loose bolts to the manufacturer's torque specifications.

3. Check Wheel Bearings

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Spin each wheel by hand to feel for roughness or listen for noise that may indicate a failing bearing.
- If noise or roughness is detected, replace the affected wheel bearing with a new component.

4. Test Electric Motor

Sub-steps:
- Disconnect the electric motor's electrical connectors.
- Use a multimeter to check resistance between the motor terminals; compare readings to manufacturer specifications.
- If readings are outside specifications, replace the electric motor.

5. Reassemble and Test

Sub-steps:
- Reinstall any removed covers and ensure all connections are secure.
- Lower the vehicle back to the ground.
- Conduct a test drive to verify that the whining noise has been resolved.
