yea, imagine I get a front diff. get it locked, some custom tom woods shafts, and a bunch of nice expensive parts and then it doesn't work, I would be stuck with all that in my garage and have to go thru the hassle of sell them and haaaa no, just get it stock and then go from there, besides I'm not a ******** offroad guy like some guys here, I'm not planning on taking ti to moab or something like that,
I think you are still missing the boat
what happens if you break down your trans and install a new tail section
then get every thing installed and a week later you find out that the T-case you bought was run for 500 miles with no oil in it and is now toast?
or the front diff had a small hair line crack and it lets go the first time you wheel it
sure any of this could happen on any thing you buy used or new
but if you buy a used 4wd KJ you can go wheel it the next day
and if any thing craps out with in the first week then the place you bought it from has a problem not you
or do what you think is right
I just do not see the big deal about selling the 2wd you have and buying a used 4wd?
in the end going to cost you the same
sell what you have for $10K ,making up numbers here
buy a 4wd with close to the same miles for $13K
cost the same as keeping what you have and making it 4wd
