FAQs

Q1: Why does my hub bearing make a noise that only appears when driving downhill?

A: Driving downhill shifts the vehicle's weight forward, increasing the load on the front bearings. If a front bearing has internal damage, the added load amplifies the noise, while rear bearings may become quieter.

Q2: Why does my new hub have a small plastic protective film on the mounting flange?

A: The film protects the machined mounting surface from scratches and corrosion during shipping. Peel it off before installation to ensure the hub seats flat against the knuckle.

Q3: Can a hub bearing failure cause my vehicle to make a vibration that is felt in the accelerator pedal only at certain speeds?

A: Yes. Drivetrain vibrations from a worn bearing can create resonance at specific rotational frequencies. The vibration may only be felt in the gas pedal when the vehicle reaches the speed that matches the damaged area's vibration frequency.
