Wheel Bearing Noise
WARNING: This page is about a different car, the 2007 Suzuki Reno, 2007 Suzuki Forenza, 2006 Suzuki Reno, and 2006 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
Wheel bearings produce a rough growl or grating sound that will continue when the vehicle is coasting and the transaxle is in NEUTRAL. Since wheel bearings are not pre-loaded, a wheel bearing noise should diminish considerably when the wheels are off the ground.
