There are lots of Transfer Cases out there, lots of Transfer Case Rebuild, Install, and Transfer Case Swap possibilities. Some even do Transfer Case Doubler Installs. If you have done a Transfer Case Swap or Doubler Install, please Post Up and share so that other XJ Jeepers may benefit from your Experiences. Thanks.

This Info is from a Transfer Case Rebuild Page.

Hope this helps.
 
My '96 XJ came with a 1997-2001 DTS207-2 NP231J Transfer Case. 1996 was a Transitional Year for XJs. Some came with this Transfer Case, others with the 1993-1995 DTS207-1 NP231J Transfer Case.

The 1993-1995 DTS207-1 NP231J Transfer Case was a Direct Bolt In. I Swapped In a Novak #SK2X Shifter Assembly as well. Works Great. One thing, I had to Spot Weld the Shift Cane to it's Bracket because it kept twisting on me. Smooth and Flawless IMHO. Before the Shifter Swap, I had some Missed Shifts. Now, everything works Fantastically.

Where do you get all this information all the time?



I have over 40 years Experience Offroading in some form or another.
I belong to 3 Clubs. One Local Club of which has 2 or 3 Rides a Week and has a Great Forum. The other 2 have Rides also, however, not as often. They also have Great Forums.
I Listen to other Offroaders (I never argue anything, I just listen). If I have a question, I will ask it politely.
I do a lot of Searches. I belong to lots of Forums.
I Research everything I do so that I may make an Educated Decision.
If what I do doesn't work out... I Post it Up so others don't make the same Mistake as I.

I am sometimes Mistaken and I admit it and accept it and Learn from it.

Hope that answers your Question.
