Checking Bearing Noise
WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
Differential Side Bearing Noise
Differential side bearing noise and wheel bearing noise can be confused easily. Since side bearings are pre-loaded, a differential side bearing noise should not diminish much when the differential/transmission is run with the wheels off the ground.
Wheel Bearing Noise
Wheel bearings produce a rough growl or grating sound that will continue when the vehicle is coasting and the transmission is in NEUTRAL. Since wheel bearings are not pre-loaded, a wheel bearing noise should diminish considerably when the wheels are off the ground.
