To test a wheel bearing, begin with a visual inspection for any noticeable damage or wear. Then, lift the vehicle and securely support it on jack stands. Grasp the wheel at the 12 and 6 o'clock positions and rock it back and forth to feel for any play or looseness, which can indicate a worn bearing. Additionally, spin the wheel by hand; a rough or noisy rotation suggests the bearing may be failing. For a more conclusive test, use a mechanic's stethoscope to listen for grinding or rumbling sounds from the bearing.
