Doh! I just noticed V6 in the profile.

OP, sell it and buy another. This project is only something you should tackle for the sake of a learning experience, and will probably require you to have alternate transportation for 30 days. Some folks on this forum could do it in a busy weekend, but if you don't know inline versus V engine configuration by sight it's gonna take you a month.

good luck

whats your time worth?

doing this swap, assuming you have the tools, knowledge, and a full parts jeep in good running order to grab parts off of will run over 1000$. sell current jeep, add 1000$ you were going to spend and get a 4wd.

this is NOT an easy task that you an do on a daily driver type of vehicle. just sourcing parts will be a pain. can some of us do it in a weekend? maybe. will it likely sit in your garage half completed for months at a time? yes.

you will need a 4wd transmission, tcase, front axle and who knows what kind of driveshafts to connect it all up. (lengths could be different) you will also need the computer/TCM stuff as well.

this undertaking is the definition of 'not worth it'

To your original questions this is what will be needed..
First off will be the computer and the transmission control module. With the pig tails attached. Then you will need a 42RE (assuming your engine) and of course make sure its the 4WD transmission.
Then you will need an complete 4WD front axle (matching gear rations for front and rear)
You will need the transfer case (231/242/249). Also will need the correct input and out put shafts.
Then you will need new/used front and rear drive shafts for the correct lengths
Also you will need the shift linkage for the transfer case (matching one), then cut out the floor of the jeep where that small coin thing is, bolt it into place..

Of course if everything goes as planned its quite an under taking, and it will require quite a bit of knowledge. If you have further questions just ask. But you will need an amazing junkyard with plenty of donor jeeps (of same years/engine) and finding the correct computers/wires/plugs that will all be correctly working.

and an realistic number to be looking at IF EVERYTHING GOES AS PLANNED on the low end will be 800-1000 and the high end 1500-2000
