Well; the driveline has failed and left me stranded in Oak Ridge, Tennessee. Turned a corner and suddenly no drive. The transmission spins freely. If you jack up a corner, the front wheel will turn with the other wheel on the ground and the transmission in Park, and it feels like slipping splines would feel like, but both axles appear to be firmly seated. It is either that, or the spider gears in the differential have failed. No prior warning or noises, except it has always had a lot of play in the driveline. I'll have to find a way back to west Tennessee to pick up my truck and trailer to get it home. Has anyone else had a spider gear failure?
