I'll try it on Jack stands with the front line out, but at this point I don't think I want to swap engines. I will try putting it in neutral at 65 mph again to rule out the engine. I've had the transfer case out because some Gomer that had it before put the transfer case back together without a gasket and just used blue sillycone and it leaked like crazy. They didn't even bother to put the brace bolt back in the engine block. Total idiots.
