FAQs

Q1: What causes a hub bearing to make a rhythmic thumping sound at low speeds?

A: Severe brinelling or large pits in the bearing raceway create distinct impact points. Each time a roller passes over a damaged spot, it produces a thumping sensation that can be felt through the vehicle.

Q2: Why does my new hub have a small foam pad between the ABS connector and the housing?

A: This foam pad acts as a vibration damper to prevent the connector from rattling against the hub body. It also provides a moisture barrier to protect the electrical connection.

Q3: Can a hub bearing failure cause my vehicle to make a squeaking noise that matches suspension movement?

A: If the bearing has excessive play, the hub can shift during suspension compression and extension, causing metal-to-metal contact that produces a squeak synchronized with suspension travel rather than wheel rotation.
