Wheel Bearing Noise
A road test can usually indicate excessive wheel bearing noise. Sealed wheel bearings emit a howling sound when the bearings go bad. This sound is
only present when the vehicle is moving. The sound is constant, unwavering and increases in loudness and pitch when vehicle speed increases. If wheel
bearing noise cannot be positively diagnosed, or if the front or rear origin of the noise cannot be determined, perform the following wheel bearing test:
1. Raise the vehicle. Support the vehicle.
2. Spin the wheels by hand. Inspect the wheels for the following conditions:
^
Out-of-round tires
^
Out-of-balance tires
^
Bent rims
^
Loose wheel bearings
3. On two-wheel drive vehicles, spin the front wheels using a commercial wheel spinner. Spin all the driven wheels using the engine.
4. If noise can be heard from the passenger compartment, replace the noisy wheel bearing's cartridge. Refer to Wheel Bearing and Wheel Hub
Replacement.
5. Lower the vehicle.
