So I was meaning to rebuild the thing but forgot. It did the explode thing and swung around. Damaged the tranny pan and knocked a hole in the tranny. I took a look and the internals seem fine in the tranny. Went ahead and welded a piece of aluminum to patch it then pulled a driveshaft and tranny pan at the junkyard. I rebuilt the driveshaft and it is at a driveline shop being balanced. Put the pan in place and filled the tranny. Truck is running fine with the CDL engaged. No vibrations or funny stuff at any speed. Can anybody think of anything I need to check before I put the drive shaft back in place. Measure runout where the drive shaft mounts on the transfer case and differential, etc?
