FAQs

Q1: What causes a hub bearing to make a grinding noise that only appears when braking lightly on a wet road?

 A: Wet roads can cause water to splash onto the brake components and bearing area. If the bearing seal is compromised, water can enter and temporarily degrade the grease, causing a grinding sound when light braking applies axial load to the damaged raceway.

Q2: Why does my new hub have a small engraved batch number on the ABS connector housing? 

A: The batch number allows the manufacturer to trace the connector back to its production batch for quality control and warranty purposes. 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 driver's door panel?

 A: Yes. Vibrations from a failing bearing can travel through the chassis and body structure, causing door panels to rattle or vibrate, especially at highway speeds where the resonance frequency matches the body's natural vibration mode.
