I've changed the front oil seal on my transfer case twice, and the dang thing is still leaking. I would really appreciate any input on what I should do. I'm pretty much at a complete loss.

Thanks,

Tim

im going to guess that either it is in backwards if it is directional or that your smooth surface on the shaft/ collar of the yoke has devloped a groove only mild but enough to allow minor oil bypas or possibly tear the seal everytime you use it replace the yoke with a neone or if its a female collar situation take it into a machineshop turn it down and sleeve it then pollish the sleeve for a new seal surface. but you definately should be looking for a inperfection in the riding surface.
