FAQs

Q1: Why does my hub bearing make a noise that only appears when the vehicle is turning right and accelerating?

A: Turning right shifts weight onto the left bearing, while acceleration adds torque load. The combination of lateral and torque loads on a damaged left bearing amplifies the noise significantly.

Q2: Why does my new hub have a small rubber bumper on the ABS wire clip?

A: The rubber bumper prevents the wire clip from vibrating against the knuckle or suspension components, which could cause wire fatigue or chafing over time.

Q3: Can a hub bearing failure cause my vehicle to make a noise that sounds like a failing differential?

A: Yes. Both can produce a whining or grinding sound that changes with vehicle speed. To differentiate, check whether the noise changes with turning (hub bearing) or remains constant regardless of steering input (differential).
