hub help please!

ok, so i am working on a 1996 pontiac grand am with a 3.1 liter engine. The steering bearing was bad so i went to napa to get a new one, and all they sell is the hub assembly. well i took the one off the car and i was gonna go put the new one on, but i dont know if i need to grease the new piece. I think there is already grease in the bearings, but i dont know if i need to grease the back of the piece before instalation. If anyone can help it would be greatly appreciated.

Steering Bearing???? Are you talking about the hub assembly that the tire bolts to?

Where's it at??
