FAQs

Q1: Why does my hub make a clicking noise that only appears when turning sharply at low speed?

A: Sharp turns place maximum lateral load on the bearing. If the rollers or raceway have localized damage, this load can cause a clicking sound as the damaged surfaces make contact.

Q2: Why does my new hub have a small metal retaining ring visible inside the center bore?

A: This ring is part of the internal bearing assembly and helps maintain the correct positioning of the bearing components. It should not be removed or disturbed during installation.

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

A: Yes. A severely worn bearing can produce a rhythmic chopping or thumping sound that resembles helicopter blades, especially at highway speeds. This indicates advanced internal damage.
