FAQs

Q1: What does "hub pilot diameter" mean and why does it matter?
A: The hub pilot diameter is the raised center ring on the hub face that centers the wheel precisely on the hub. If this diameter doesn't match your wheel's center bore, the wheel won't be centered properly, causing vibration even with new lug nuts torqued correctly.

Q2: Can a hub bearing failure cause my lane departure warning system to malfunction?
A: Yes. Lane departure systems use wheel speed data to calculate vehicle trajectory. Erratic signals from a damaged encoder ring can confuse the system, causing false warnings or preventing it from functioning at all.

Q3: Why do some hubs have a small vent hole on the back?
A: This vent equalizes internal air pressure as the bearing heats up and cools down during operation. Without it, pressure buildup could push the seal outward, allowing grease to escape and contaminants to enter.
