It save me one time I had removed the oil pump - I forget why - and messed up in the reinstall. Spun it up with the drill and there was no pressure in the accusump.
I guess that's kindof like where I am with the Jeep's front end. Haven't ahd to go this deep before and so its a slower more painful process. However punching the hub's casting where the outer race seats instead of the back of the inner race was just being stupid.
