Is there such thing as a "wheel hub assembly" for the front 05 g35x that comes with bearings and hubs together in one piece/pressed. I found TIMKEN has a wheel hub assembly at parts geek.

I'm a bit skeptical because as far as I know its suppose to be 2 separate pieces.( hub and bearing). Can anyone confirm this?
