FAQs

Q1: Why does my hub bearing make a humming noise that gets quieter when I lightly apply the brakes?

A: Light braking applies a small axial load that temporarily shifts the bearing internals, changing the contact pattern and sometimes silencing the noise. This often indicates early-stage wear.

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 vibration that is felt in the seat cushion on the driver's side?

A: Yes. A failing left-side rear bearing can transmit vibration through the suspension and chassis into the driver's seat. If the vibration is strongest in the seat rather than the steering wheel, check the rear bearings first.
