FAQs

Q1: What causes a hub bearing to make a grinding noise that is constant regardless of turning direction?

A: Constant grinding regardless of turning indicates severe internal damage where both sides of the raceway are worn. This is an advanced failure stage requiring immediate replacement.

Q2: Why does my new hub have a small white marking on the ABS encoder ring?

A: This marking indicates the magnetic polarity orientation for quality testing during manufacturing. It has no functional purpose after installation and can be ignored.

Q3: Can I install a hub assembly if the ABS connector feels slightly loose?

A: No. A loose connector can cause intermittent signal loss, triggering ABS and stability control warning lights. The connector must fit snugly with an audible click when fully seated.
