i had bought a 1998 jeep cherokee XJ for cheap. the only bad thing is that it is NOT 4x4! i am goin to change that. i am not worried about the money aspect of it, but i was wondering if it is even possible. i know that i need a front axle, front drive shaft, transfer case, and probabily a new rear drive shaft. BUT do i need a new trans? if anyone knows please let me know. thanks
