FAQs

Q1: Why does my hub bearing make a humming noise that gets louder on the highway?

A: Highway speeds increase the rotational frequency of the bearing. If the raceway or rollers have wear patterns, the vibration frequency rises with speed, making the hum more noticeable at higher velocities.

Q2: Why does my new hub have a small plastic bag attached to the ABS wire?

A: The bag keeps the wire and connector clean and protected from dust during storage and shipping. Remove it before installation and route the wire along the factory path.

Q3: Can a hub bearing failure cause my vehicle to pull to one side during braking?

A: Yes. Excessive play in the bearing can cause slight wheel misalignment under braking load, pulling the vehicle toward the side with the worn bearing.
