FAQs

Q1: What causes a hub bearing to make a humming noise that only appears when driving on coarse asphalt? 

A: Rough road surfaces excite the bearing's natural vibration frequency more than smooth pavement. If the bearing has minor wear, the increased vibration from coarse asphalt can amplify the humming sound, which may be less noticeable on smooth concrete.

Q2: Why does my new hub have a small raised dot on the ABS sensor housing?

 A: This dot is a manufacturing reference mark used during assembly to verify correct sensor positioning relative to the encoder ring. It has no functional purpose during installation.

Q3: Can a bad hub bearing cause my vehicle to make a vibration that is felt in the floor pan? 

A: Yes. Vibrations from a failing bearing travel through the suspension and subframe into the floor pan. The vibration is often most noticeable under the driver's or passenger's feet, depending on which side the bearing is located.
