    2000 XJ with an auto transmission with part time 4wd. im assuming it is possible to convert to full time and that i would need a full time transfer case along with new front and rear diffs?

    Isn't full time 4wd called AWD? I dont know that it is possible to have true 4wd full time if you drive on pavement unless you like burning through tires, differentials, and transfercases like underwear.

    sorry, guess i did a poor job of explaining what i wanted to know

    atm, my xj has the command trac 4wd system. what i want to know is if i can install the selec trac 4wd system and to do that i would just need to get a selec trac transfer case and selec trac front and rear hubs.

    you would just need the transfer case.

    no hubs on an XJ, they are direct drive (unless you have CAD in the front axle ... but that is easy enough to get rid of).

    why do you want AWD on your xj? it burns more fuel in 4wd and is pretty pointless ... if you need power to all 4 tires in order to safely navigate your town, then there is enough slip to use the 4wd already installed on your xj ... no need for a center diff.

    transfer case: yes
    hubs: no
    diffs: no

    just make sure all the linkage and electrical / vacuum connections will swap over from the new case to your xj

    atm my part time 4wd isnt working, if i put it into 4hi it feels like it starts to seize up and i have a hard time getting it back into 2hi. so im thinking it might either be the front diff or the transfer case. if it did turn out to be the transfer case and the selec trac was interchangable then i would just swap it in. it is also my understanding that selec trac still has a 2hi in addition too full and part time 4hi.

    It will feel like that if you're trying to use 4wd on dry pavement. If its having trouble shifting back to 2hi, back up a bit, it will free things up.

    I'd replace it with another 231 personally, its a bit stronger t-case and has much more aftermarket support (SYEs, 4:1 conversions, etc) Of course I'm in Socal and won't ever need full time 4wd.

    nm, the more im looking into this the more in depth it seems to be. also quite costly.

    yeah ...

    if you are going through the trouble of swapping cases ... bite the bullet and swap in a np241OR out of a rubicon and be done with it.

    Islander ... cant you also just grab the driveshafts out of the rubi and make it a direct bolt in ... no swapping yokes on the case .... AFAIK, the shafts are the same length

    Front might work? Rear no way.

    If I were in the market for case upgrades I'd go straight for a 241OR
