You should use the socket so you can torque the nut. If the nut backs off it will kill the upper chaincase wobble bearing. I had this happen on a customer sled and had to do job twice.... live and learn I guess. The bearings pop right out if you apply a little heat with a propane torch. Job is not fun but not real hard. I would replace all the bearing just for a piece of mind.
