FAQs

Q1: Why does my hub bearing make a noise that only appears when I drive over expansion joints?
A: Expansion joints create sudden vertical impacts that momentarily spike the load on the bearing. If the raceway has pitting or spalling, these impact loads can cause the rollers to bounce or chatter, producing a brief clunk or rattle that doesn't occur during smooth driving.

Q2: Why does my new hub have a small plastic cap over the center bore?
A: The cap protects the precision-machined bore surface from scratches, dirt, and corrosion during shipping and storage. Remove it before installing the axle shaft to ensure a proper fit.

Q3: Can a hub bearing failure cause my vehicle to make a noise that sounds like a loose muffler?
A: Yes. A severely worn bearing can produce a low-frequency rumbling or rattling sound that resonates through the chassis, mimicking the sound of a loose exhaust component. Check for bearing play before inspecting the exhaust system.
