FAQs

Q1: What causes a hub bearing to make a ticking noise that only appears at very low speeds?

A: At very low speeds, individual roller impacts against raceway damage become audible as distinct ticks. At higher speeds, these impacts blend into a continuous hum or growl.

Q2: Why does my new hub have a small dimple on the ABS sensor body?

A: This dimple is a manufacturing reference point used during quality inspection to verify sensor alignment. It has no functional purpose during installation.

Q3: Can a bad hub bearing cause my vehicle to make a vibration that gets worse when going uphill?

A: Yes. Driving uphill increases the load on the drivetrain and bearings. If the bearing has internal damage, the additional load can amplify the vibration.
