98 jeep grand cherokee

I have a question. My jeep is the AWD model and I want to know the best way to make my jeep part time 4wd. Is there some kind of conversion kit or anything I can do? Help! Thanks

Oh its a Dana 30 with 3.55 ratio. I believe it is the 249 t- case. Thanks

I just did some quick research (I don't know much about AWD vehicles), and it looks like you'll need a transfer case, then the driveshaft and input shaft lengths will need to be checked.

I've swapped in 231s and 242s into ZJs to replace the problematic 249. Since it's a 98 it'll have the 42RE transmission so find another ZJ from 94-98 for a doner. The one's I've swapped were both 93s and had the AW4 transmission just like a XJ so it was a little easier to find. You may be able to use a case from an XJ, never tried but you'll need one with a 23 spline input, 91 and later, and match the length. Drive shafts will bolt up to the new case.

So the transmission needs to be replaced or no?

No transmission will be fine just the transfer case needs swapped out.
