FAQs

Q1: What causes a hub bearing to make a metallic scraping sound after driving through a puddle?

A: Water can wash away grease from compromised seals and carry debris into the bearing. The debris creates a scraping or grinding sound as the rollers drag it across the raceway surfaces.

Q2: Why does my new hub have a small QR code sticker on the box?

A: The QR code links to the manufacturer's product page, installation instructions, or warranty registration. It is not part of the hub itself and should not be installed on the vehicle.

Q3: Can a bad hub bearing cause my vehicle to make a noise that sounds like a failing alternator?

A: Yes. A bearing with degraded grease can produce a high-pitched whining sound similar to a failing alternator bearing. To distinguish between the two, check whether the noise changes with vehicle speed (hub bearing) or engine RPM (alternator).
