FAQs

Q1: What causes a hub bearing to make a rumbling noise that is worse on rough roads?

A: Rough roads increase the vertical load and impact forces on the bearing. If the raceway has pitting or spalling, these impacts amplify the rumbling sound.

Q2: Why does my new hub have a small engraved lot number on the housing?

A: The lot number allows the manufacturer to trace the unit back to its production batch for quality control and warranty purposes.

Q3: Can I install a hub assembly if the ABS wire has a slight kink in it?

A: No. A kinked wire can develop internal breaks that cause intermittent signal loss, leading to ABS and stability control faults. Replace the hub if the wire is damaged.
