I recently replaced my old pathy with another old one (I am hooked). The "new" one is a 95' Pathfinder SE 4X4 (Auto). I didn't try putting it in 4WD when test driving it but tried it later and all was fine until I tried to disengage it. The lever shifts fine and the green indicator light goes off but I hear a noticeable whine out of the transmission as if it is still locked in. I thought maybe it was just the hubs that were gummed up and not releasing, but when I jacked it up both front wheels spin free. Anyone ever run into this problem? Any ideas on things to check?
