Hey guys. I've got an 06 TJ with the 2.4 and 6 speed. I'm trying to find out what transfer case will fit on the end of my transmission. My current transfer case has a nasty leak out if the tail housing, there's play in the output shaft to the rear wheels, and you can hear something in there clunking about half the time when I shut the Jeep off. I'd just rebuild it but the Jeep is my daily and I don't have time to mess around with rebuilding one. What can I snag a used case from to throw on? I'm getting all kinds of info from all kinds of different sources and now I'm all kinds of confused. I know it's an NP231J but that's about it. Any help would be awesome. Thanks guys.
