FAQs

Q1: Why does my hub bearing make a noise that only appears when the vehicle is turning right and braking downhill? 

A: Turning right shifts weight onto the left bearing, while braking downhill adds axial load and increases vertical load due to weight transfer. The combination of all three loads on a damaged left bearing amplifies the noise significantly.

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 bad hub bearing cause my vehicle to make a vibration that is felt in the glove box?

 A: Yes. Vibrations from a failing bearing can travel through the chassis and body structure, causing the glove box latch or contents to rattle, especially at highway speeds where resonance frequencies align.
