You can just read the specs but I'll just tell you so you don't have to put forth the effort. It's got a D44a in the rear(same used in Vipers and Corvettes), thicker rear drive shaft, and the same transmission used in full size Dodge trucks. 46RE. The 5.2 has a 44RE. The 249 has a bigger input or output shaft I think. The one bad thing about it is no auxiliary transmission cooler but you can add one.

It should have the aux cooler from the tow package though right? Maybe tow package was still optional? I know my 96 w/ tow package has the cooler, and I assume my niner does.

No. Aux coolers discontinued on all 98 models after radiator redesign which was a bad idea.

Not to the point you need to own a tire tread depth gauge & need to know the nearest shop that shaves tires when they get out of whack. Throw the spare into the rotation & you have a real headache.

I have a Niner and haven't driven a 5.2 to compare, but I can tell you the thing is POWERFUL, riding around with my exhaust valve open, its louder than any truck on the road, and definitely has the speed to back it up. I wouldn't have gone out of my way to find one, but an opportunity fell on my lap when my friend sold his to me for 1,100 bucks. Couldn't go wrong for that price.

the "special" 249 for the 5.9, which isn't marked as special in ANY way, supposedly has a beefier main shaft, wider chain, and more planetary gear pinions.
Ratmonkey quote. http://www.jeepforum.com/forum/f13/9...-shaft-960607/

I can't verify this but I have read that it was stronger in some way.

The VC in mine lasted 130k miles. I'm happy with it lasting until 260 k miles after replacement.

Here is a quote from a fellow from expedition portal about the 249

that's what i've heard from a few of the people that regularly rebuild the jeep cases. 6 pinion planetary, wider chain, and thicker main shaft. outputs and inputs are the same though.
the rear driveshaft uses 1330 or 1350 joints, i forget which, but i know they're bigger than the 1310 joints a normal zj uses.

I ordered a 98 Limited with a 5.2 because the salesman never told me about the 5.9 or offered me a test drive of one. When it finally came I liked it loads more than my 4.0 G C. The day my lease was up, I wrote a check and paid off the 5.2 and went looking for a 5.9. Found one with lower miles than my 5.2 and worked a deal. I have never once regretted my move to the 5.9. I will probably drive it till all the oil in the ground is gone or I am in the grave.

The mainshaft is the only difference in the 5.9's 249 . Parts list has the same listing for all other parts including the input shaft and chain .
