Is this a known problem ?

I hit the hard tracks had 2 decent hits underneath my 92 Gq waggon, I already had a slow leak under my gear box but when I was airing up after the tracks I saw a wet spot under the Patrol and g/b fluid was dripping out and not a slow drip ethere, and yes it was g/b oil because my transfer case has ATF in it,I have diagnosed that the oil is coming out of the out put shaft to the transfer case, now I am hoping it is just the seal has blown out but I was wondering has anyone else come across this and was there something more sinister happening from the g/b to cause the shaft to lose it's centre position?

Sorry mate, I'm confused. You have ATF in your Transfer box? Is the car an auto or manual?

It is a manual but I read that ATF was better for the transfer case, it was after that I found out that you do that for the auto hubs because of the drag from normal g/b oil.
