My daughter had a major incident yesterday. The rear Ujoint at the differential failed and the driveline came off. It's destroyed. The transmission mount broke. There's a hole in the transfer case and the output shaft housing area of the 700R4 broke off. Not the 4WD adapter, but the actual transmission housing in front of that. I don't even know where to start. I have never had a transmission or transfer case housing fail before. Both housings are ruined so they're worthless as cores. I'm pretty sure the transfer case is totally done and I need to find another one. What about the transmission? Can the internals be put into a new housing? Has anyone else had a situation like this?

Something similar happened on my son's K10. His was ran without fluid & the case locked up, spitting out the rear shaft & breaking the rear housing of the trans & destroying the case.
You can swap the internals from the case BUT I'd be very scrutinous with inspection for component re-use. You'd probably be better off to find replacements for the druveshaft, case & trans.
