Which way does the oil tend to go if seal is bad TC or tranny ?
In a Landcruiser it always pumps from the transfer to the tranny. In a Jeep it is normally the other way around. It pumps from the unit that has the higher pressure to the unit with the lower pressure. The hose helps reduce the pressure differential and lets the excess pumped into the tranny drain back to the transfer case.
I believe when the seal is failing, it pumps to the tranny, and once the seal has fully failed it goes tranny to t-case...
Moral of the story: check fluid in both
