FAQs
Q1: Why does my hub make a whining noise that changes when I shift between gears?
A: Gear shifts change the torque load on the drivetrain and bearings. Different load conditions shift the contact pattern inside the bearing, which can alter the noise frequency or intensity.
Q2: Why does my new hub have a small plastic spacer inside the center bore?
A: This spacer protects the precision-machined bore surface from damage during shipping. Remove it before installing the axle shaft or brake rotor.
Q3: Can a hub bearing failure cause my vehicle to make a noise that sounds like a worn belt?
A: Yes. A bearing with degraded grease or surface wear can produce a high-pitched whining or squealing sound similar to a worn serpentine belt, especially at idle or low speeds.
