FAQs

Q1: What causes a hub bearing to make a humming noise that is louder on one side of the road crown?

A: Road crown causes the vehicle to lean slightly, shifting more weight onto one side. The bearing carrying more load will produce a louder noise, while the unloaded side may become quieter.

Q2: Why does my new hub have a small notch on the outer race?

A: This notch is a manufacturing reference mark used during assembly to verify proper component alignment. It has no functional purpose during installation and can be ignored.

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

A: Yes. Drivetrain vibrations from a worn bearing can travel through the axle, transmission housing, and into the shifter linkage, creating a noticeable shake in the gear lever.
