Tony, why the transfer box neutral? It's not necessary, if you can test just by jacking one front wheel then you can test just by turning (or attempting to turn) the front output shaft as long as the gearbox is in neutral for a manual and not in park if it's an auto.
Yeah i know Keith. But with transfer in neutral you are not turning gearbox shafts, just makes it that much easier to do. He only has a socket and ratchet. I would not normally do that, would use a torque wrench or 18" bar, but just giving him a chance of moving it with what he has, if it's going to move. I know UJ looked dry and that could be the problem, but still leaning towards VCU seized to be honest.
