FAQs

Q1: Why does my hub bearing make a noise that only appears when the vehicle is carrying a heavy load in the trunk? 

A: Additional weight in the trunk increases the vertical load on the rear bearings. If the bearing has existing wear, the extra load compresses the internal components more tightly, amplifying friction and noise.

Q2: Why does my new hub have a small rubber grommet where the ABS wire exits the housing? 

A: This grommet seals the wire exit point against water, dust, and road salt. It prevents moisture from reaching the internal sensor connection and causing corrosion.

Q3: Can a hub bearing failure cause my vehicle to make a noise that sounds like rocks in a tin can?

 A: Yes. Severely damaged bearings with broken cage fragments or loose rollers can produce a rattling sound similar to objects shaking inside a container. This indicates critical failure requiring immediate replacement.
