On a logging road in four wheel high the transfer case jumped out of gear. It made grinding sounds (gears) anywhere I put it. I got it only in four wheel high and headed home forty miles away. I could smell transmission fluid all the way home. I changed the fluid one month ago and it had water in it. I don't know the history of the Jeep. I guess it's time for a used one. 1998 4L auto sport. I want to make sure I get the right one. Is it a 23 spline long shaft? Ebay talks about a Sport and a Sport Sport. Can you guys tell me exactly what I need. Thanks as always.
