First off, Its been awhile since I have been on here. I have searched and have come up with mixed results for the answer that I am looking for.
I have a 1990 4 door XJ with a swapped in 87 4.0L with the original 90 AW4 Trans and T case. I believe that the original Tcase is going out.
I lucked into finding a wrecked high mileage 1993 4.0L HO with the AW4 trans and NP231 Tcase. Although it has 199k on it it was owned for the majority of its life by a friends grandmother who bought it new and had it serviced regularly. It was given to my friends sister who had it less then 2 years and she wrapped the rear end around a telephone pole. It does not smoke and shifts good and the 4WD was most likely only used minimally over the years and never abused.
I have been trying to find out whether I can just swap the T case in or if I am going to have to do more than that. I have read about the different spline counts and I dont really want to crack the cases and swap out the shafts.
I have scrapped out the body of the vehicle, however I kept the most important parts. I have the engine, Tranny, T case the Hi pinion Dana 30 front, radiator and the ECU.
If I have to do a major swap I might just swap the shortblock, tranny and Tcase all in. I would prefer to just do the Tcase.
Any advice on what spline counts are between the engine, tranny, and T case and what will work with what would be very helpful.
Thanks in advance for you help.
