I just tried this this past weekend. It didn't really help because the back end of the axle-end mount is wallowed as well (it did still tighten it up a bit). What does one do about that? I read GoJeeps bit about using copper as a backing plate to allow weld to fill the original back hole and redrilling, but otherwise, what's one left to do? As far as going to 7/16," I can't get a 7/16" bolt through the track-bar bushing, and I don't want to fry the bushing trying to drill it out.
