FAQs

Q1: What causes a hub bearing to make a whining noise that only appears when coasting?

A: Coasting removes drive torque from the bearing, changing which internal surfaces carry the load. If damage is on the coast-side of the raceway, the whine may only appear when the load shifts during deceleration.

Q2: Why does my new hub have a small raised bump on the ABS sensor housing?

A: This bump is a manufacturing reference point used during assembly to verify correct sensor positioning. It has no effect on installation or performance.

Q3: Can a bad hub bearing cause my vehicle to make a vibration that feels like the wheels are out of balance?

A: Yes. A worn bearing creates uneven rotation that mimics the sensation of an out-of-balance wheel. If rebalancing the tires does not resolve the vibration, inspect the hub bearings.
