FAQs

Q1: What causes a hub bearing to make a clicking noise that only appears when the vehicle is turning left and braking downhill?

 A: Turning left shifts weight onto the right bearing, while braking downhill adds axial load and increases vertical load due to weight transfer. The combination of all three loads on a damaged right bearing can produce a clicking sound.

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 hub bearing failure 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).
