FAQs

Q1: Why does my hub bearing make a noise that only appears when the vehicle is turning left at highway speeds?

A: Turning left at high speed shifts significant weight onto the right-side bearing. If the right bearing has internal damage, the high lateral load amplifies the noise, while the unloaded left bearing may become quieter.

Q2: Why does my new hub have a small rubber grommet where the ABS wire exits the housing?

A: This grommet seals the wire exit point against water, dust, and road salt. It prevents moisture from reaching the internal sensor connection and causing corrosion.

Q3: Can a hub bearing failure cause my vehicle to make a vibration that is felt in the steering wheel only when braking?

A: Yes. A worn bearing allows the hub to wobble slightly, which transfers uneven rotation to the brake rotor. When the brakes are applied, the pads clamp onto the warped rotor surface, creating a pulsation that travels through the steering column.
