You wouldn't necessarily need hubs but you would need an axle because it's drilled to allow the grease to go to the inner bearing. When you pop the rubber cap off the the metal grease cap the zerk is there. It's threaded into the end of the axle. The hole is drilled all the way back to the inner bearing area. As grease pushes through the inner bearing it moves out and through the outer bearing.
