FAQs
Q1: What causes a hub bearing to make a squealing noise only when the vehicle is turning?
A: If the bearing has excessive play, the hub can shift slightly during cornering, causing internal components to rub against each other under lateral load. This creates a squealing or rubbing sound that appears only during turns.
Q2: Why does my new hub have a small engraved arrow on the housing?
A: Some hub assemblies are directional and must be installed in a specific orientation relative to the ABS sensor or knuckle. The arrow indicates the correct installation direction — always follow the manufacturer's instructions.
Q3: Can a hub bearing failure cause my vehicle to make a vibration that is felt in the steering wheel?
A: Yes. Front hub bearing failures typically transmit vibration through the steering linkage into the steering wheel. The vibration usually increases with vehicle speed and may become more pronounced during turns.
