FAQs

Q1: Why does my hub bearing make a noise that only appears when the vehicle is turning right at low speed in a parking lot?

A: Turning right at low speed places maximum lateral load on the left-side bearing. If the left bearing has internal damage, the added load amplifies the noise, while the unloaded right bearing may become quieter.

Q2: Why does my new hub have a small plastic protective 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.
