FAQs

Q1: What causes a hub bearing to make a buzzing noise that only appears at a specific speed range?

A: Specific damage patterns create resonance at particular rotational frequencies. The buzzing appears when the wheel reaches the speed that matches the damaged area's vibration frequency and disappears outside that range.

Q2: Why does my new hub have a small raised ring around the ABS sensor mounting area?

A: This ring acts as a locating feature that ensures the sensor is positioned at the correct distance from the encoder ring for accurate signal reading.

Q3: Can a hub bearing failure cause my vehicle to make a vibration that is felt in the floorboard on the driver's side only?

A: Yes. A failing left-side rear bearing can transmit vibration through the suspension and chassis directly into the driver's side floor area. The location of the vibration often corresponds to the side of the failing bearing.
