FAQs

Q1: What causes a hub bearing to make a squeaking noise that only appears in wet weather?

A: Moisture can penetrate compromised seals and reach the bearing internals. Water contamination degrades the grease and causes metal-to-metal contact, producing a squeak that may disappear once the bearing dries out.

Q2: Why does my new hub have a small colored stripe on the ABS connector?

A: The color stripe is a visual identifier used during manufacturing to distinguish connector types or wire configurations. It helps ensure the correct part is matched to the vehicle application.

Q3: Can a bad hub bearing cause my vehicle to make a vibration that is felt in the brake pedal?

A: Yes. Hub runout transfers to the brake rotor, and when the pads clamp down during braking, the uneven rotor surface creates a pulsation that travels through the brake pedal.
