I've got a 2006 Coleman Cobalt (Fleetwood Element) and the threads on the end of the drive shaft are slightly stripped. Got the new drive hub extension assembly hoping that was the issue. it was partly, but the new coarse thread nut isn't going onto the drive shaft due to the stripping. Drive hub extension is part #4716A1741 Drive shaft is #4751A3701 Want to try a die set and fix the threads because I won't get the new drive shaft in time for my trip coming up. Anyone have any idea?
