FAQs

Q1: What causes a hub bearing to make a grinding noise that only appears when the vehicle is turning left and accelerating?

 A: Turning left shifts weight onto the right bearing, while acceleration adds torque load. The combination of lateral and torque loads on a damaged right bearing amplifies metal-to-metal contact, producing a grinding sound.

Q2: Why does my new hub have a small colored stripe on the ABS connector? 

A: The color stripe is a visual identifier used during manufacturing to distinguish connector types or wire configurations. It helps ensure the correct part is matched to the vehicle application.

Q3: Can a hub bearing failure cause my vehicle to make a noise that sounds like a failing transmission? 

A: Yes. Both can produce a whining or grinding sound that changes with vehicle speed. To differentiate, check whether the noise changes with turning (hub bearing) or remains constant regardless of steering input (transmission).
