Transfer Case problems

[knight120287]

I am trying to get a 1989 yj back on the road. I inherited it with a transfer case broken in half, and some bent springs and rims. I just bought a transfer case (np231) and swore the guy told me it came off of am Ax-15 transmission like mine has. but after i bought it(a whole $100) I found out it was a typo, it was off a Ax-5. The new one has 21 splines, and I need 23 splines. Could I just change the splines from the old one into the new one? Or are the insides wrong also? Or would it be a bad idea to try and switch out the guts? Thanks for the help

Talk to one of your local junkyards and see if they would let you swap the broken TC and the 21spline TC for the correct 23spline TC. Besure to keep your mechanical speed-o-meter from the older TCs. This way it shouldn't matter if you get a TC with one of the electronic pulse speed o meters or a mechanical cable style like you currently have.

Thanks BaconYJ. The local junkyards are asking like 600-700 dollars for the transfer case I need. I dont think they would take my two for a trade.

You can use the input shaft from your broken transfer case into the good one, depending on the year of the good transfer case. What year is the good TC?

the good TC is also out of a 89. Just changing the input should work? Nothing is different inside? No gearing change or anything?
