FAQs

Q1: Can a failing hub bearing cause my vehicle to pull to one side while driving straight?

A: Yes. A worn bearing creates uneven rotational resistance, which can make the vehicle drift or pull toward the side with the failing bearing, especially at higher speeds.

Q2: Why does my new hub have a small zip tie holding the ABS wire?

A: The zip tie keeps the ABS wire secured against the hub body during shipping to prevent it from snagging or getting damaged. Cut it carefully during installation and route the wire as the original was routed.

Q3: Can I grease the hub mounting surface before installation?

A: A very thin layer of anti-seize compound is acceptable on the hub-to-knuckle mating surface to prevent corrosion. However, never apply grease to the bearing itself — it is pre-lubricated and sealed for life.
