I did my right front today. I replaced the old ball bearing type with tapered roller bearings. If I tighten the castle nut just enough so that there is no wobble in the hub, it feels a bit tight to me. The hub turns by hand, but it just feels a little stiff. If I back off one notch on the castle nut, I get a little wobble. I think I'm at the right spot but I just wanted to know how easily the hub should turn. No problems when I drive it, by the way.
