yea this is definitely not a loose ball bearing with cone nuts. in the pic, you can see the axle connected to the bearing that's recessed behind the freehub body. on the other side, the bearing is more visible. I did not try to force the bearing in or out. It seemed pretty solid in place to me. About how much force do you need to get those out? It would make more sense to me that they're pressed in, instead of just sliding in, which doesn't seem to be a very stable interface to me.
