FAQs

Q1: Why does my hub bearing make a noise that only appears when driving over rough roads?

A: Rough roads create constant vertical impacts that momentarily spike the load on the bearing. If the raceway has pitting or spalling, these impact loads can cause the rollers to bounce or chatter, producing a rattling or grinding sound that doesn't occur on smooth pavement.

Q2: Why does my new hub have a small plastic cap over the ABS connector pins?

A: The cap protects the connector pins from dust, moisture, and physical damage during shipping and storage. Remove it before plugging the connector into the vehicle's wiring harness.

Q3: Can a hub bearing failure cause my vehicle to make a noise that sounds like a loose exhaust hanger？

A: Yes. A severely worn bearing can produce a low-frequency rattling or buzzing sound that resonates through the chassis, mimicking the sound of a loose exhaust component. Check for bearing play before inspecting the exhaust system.
