Thanks to all for the assistance, much appreciated. Not sure why the gear got hot and melted, haven't been that far in to it yet. Although the black driven gear did have green plastic on it so it is probably destroyed. I have an apointment at RUSH Truck repair in OKC, they are a Ford large truck repair facility so we'll see. I wish I dared to drop the driveshaft and rip into it myself. I called and made the apointment with RUSH right after my first post as I need the RV for a trip in a couple of weeks and these things have a way going on and on and on! Thanks all!
