FAQs

Q1: What causes a hub bearing to make a grinding noise that only appears when the vehicle is in park and the engine is running?

A: This is unlikely to be a hub bearing issue, as the wheels are not rotating in park. The noise is more likely coming from the engine, transmission, or accessory drive components. Hub bearing noise only occurs when the vehicle is moving.

Q2: Why does my new hub have a small engraved arrow on the ABS sensor body?

A: Some sensor assemblies are directional and must be installed in a specific orientation. The arrow indicates the correct installation direction relative to the encoder ring — always follow the manufacturer's instructions.

Q3: Can a bad hub bearing cause my vehicle to make a noise that sounds like a failing power steering pump?

A: Yes. Both can produce a whining or groaning sound that changes with steering input. To differentiate, check whether the noise changes with vehicle speed (hub bearing) or steering wheel position (power steering pump).
