OK, so I have a buddy with a ZJ, and he is wanting to get rid of the 249 AWD t-case in it, in exchange for a 231. It is a 1998, auto, 5.2 liter V8 ZJ. What cases should he be looking at for the best swap here? I just do not know what will bolt up to that tranny, so help a buddy out here, please!! Thanks in advance guys!!

people usually go with a 231 or 242, iirc all you have to do is swap the imput.

i just did a quick google and came up with this, it seems pretty through.

jyaughn

Anybody know of swaps that don't require an input shaft change??

Whats the output you're trying to match?

COSXJFAN

Not sure Frank, it is the auto tranny from a 98 zj with a 5.2 if that helps you at all. IDK spline counts or anything. We do not have it pulled yet, because we are trying to track down a t-case first. It is not mine, so I know very little about it, honestly. Any input is appreciated!!

You can also contact BigDave on MallCrawlin or co4x4. He's done the swap too.

Thanks Frank, is there a Jeep forum you're not on?? LOL!!

Tons of 'em! I joined Mallcrawlin when I need to ask some questions regarding cam lobe dimension and geometry questions. I'm not a regular over there.

If you own a Grand.....Mallcrawlin is a requirement. If it has been done it is on there.

But Mallcrawlin isn't the place for basic newb questions... Just remember that.
