Those studs are a press fit anyway. check if the splines on the stud are damaged. also check the hub itself for damage. If nothing is damaged, you can just "press" it back into place by tightening a open ended lug nut down on it. Thats a pretty standard procedure. If you don't feel comfortable doing that, or there is damage, you can remove the hub with a slide hammer. They are designed to be removed because of the hub over rotor design. you do not have to remove the whole knuckle, but it may be easier if you have a shop press.
