Transfer case

[WEST OZ H2]

Guy's,
Has anyone ever removed the front drive shaft, locked the transfer case into 4 Hi lock and driven for any great distance. I've done it on a constant 4WD Landrover defender in the past, but that has a bolt on flange both ends of the front drive shaft, so one doesn't need to worry about the oil coming out. I'm wondering if I could drive it if I were to just unbolt the front of the drive shaft at the diff, remove the back uni and leave the yoke in the transfer case.

Any thoughts before I rip it to bits.

I've got an issue in the transfer case in that I get an abnormal amount of windup when doing sharp turns on pavement. I think I cooked it on my last trip when towing the van through rough terrain.
I towed the van 1900Km home with it in this condition and had no issues whilst on paved roads. I have to head back to work and don't have time to strip and look at it.

Would anyone know where I could pick up a used unit (transfer case) in the US and what a rough price would be.

Thanks,
Al
