I have a 90' XJ that needs some t-case work, right now I believe it has a NP242 in it with an auto and 4.0L. I don't drive it much so tell ya the truth I'm not very friendly with it. Long story short, transfer case started making noise and I checked the fluid level and it was just about dry! I've got prices as high as $1100 to rebuild it and as low as $575 for a bone yard special. Both prices seem kind of high for a T-case so at these prices I was woundering if there are any aftermarket options or other types of cases that will work for a 90' XJ with a Auto and 4.0L?
