FAQs

Q1: Can a hub bearing failure cause my vehicle to make a vibration that feels like a flat tire?

A: Yes. A worn bearing creates uneven rotation that mimics the sensation of a flat or out-of-balance tire. Before replacing the hub, rule out tire issues by checking pressure and balance.

Q2: Why does my new hub have a thin film of oil on the exterior?

A: This is a corrosion-preventive coating applied at the factory to protect the hub during storage and shipping. Wipe it off the mounting surfaces before installation, but it does not indicate a leak.

Q3: Can I drive with a hub bearing that has slight play?

A: No. Any measurable play means the bearing is failing. Even small amounts of play will worsen quickly and can lead to sudden failure, wheel seizure, or loss of control.
