Checking Bearing Noise
WARNING: This page is about a different variant/trim than selected.
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.
