Wanderin Posted August 11, 2008 Share Posted August 11, 2008 I would like to take the 242 case out of my 89XJ which is 4.0L, Aw4, 242 and put it in my 90MJ which is 4.0l, Aw4, 231. Why? Because i plan on driving the 90MJ as my winter vehicle and the 242 Full Time 4x4 is alot easier to deal with when driving on roads that are patchy with ice/slush/dry spots. Anyways, is it just a straight swap of the T-cases or is there more to it? Link to comment Share on other sites More sharing options...
mfpdm Posted August 12, 2008 Share Posted August 12, 2008 Pretty much. I'll be doing the same swap in the Wild build. Thing to remember is that the 242 came with the non-cad axle and you may need to supply the vacuum for it which came or went through the 231. Not a problem if you are swapping the axle that came with it, which also has the bigger u-joints. That's the only thing I can think of with the exception of the shifter guide that has an extra position on it. (4x4 shift lever thingy) :D :cheers: Link to comment Share on other sites More sharing options...
