FAQs

Q1: What does "sealed for life" mean on a hub bearing?

A: It means the bearing is pre-greased at the factory and sealed to prevent contamination. It should never be opened, repacked, or serviced — only replaced as a complete unit.

Q2: Can I use a hammer and punch to remove the old hub from the knuckle?

A: This is not recommended. Hammering can damage the knuckle mounting surface or distort the new hub during installation. Use a proper hub puller or press tool.

Q3: Why does my new hub have a different number of ABS sensor wires than the old one?

A: This indicates a part mismatch. Different vehicles use different sensor configurations. Return the part and verify the correct application for your vehicle.
