Solution

1. Preparation

Gather tools: a jack, jack stands, a torque wrench, and a sound meter (if necessary).
Ensure the vehicle is on a flat surface and turned off.
Disconnect the 12V battery for safety.

2. Inspect the Tires

Lift the vehicle using the jack and secure it with jack stands.
Remove the wheel covers if applicable.
Inspect tires for uneven wear or damage, which could produce noise.
Check tire pressure and adjust to the manufacturer’s specifications.

3. Check Wheel Bearings

With the wheel lifted, spin the wheel by hand and listen for any grinding or roughness.
If noise is present, remove the wheel and check the wheel bearing for wear.
If necessary, replace the wheel bearings using a press or specialized tool.

4. Inspect the Drive Unit

Reconnect the 12V battery and power on the vehicle.
Place the vehicle in Drive and listen for abnormal sounds coming from the drive unit.
If a loud hum persists, consult the service manual for specific diagnostics on the drive unit.
