Wranglers are deceptively heavy. They're small, but the body on frame setup weighs a lot more than a unibody. XJs are light for their size.

410lbs seems like a BIG difference on the front axle. Were there any differences in engine, tranny, etc? I can't think of what could possibly add that much weight to the front end. Thinking about work I've done on my Jeep, the front axle shafts are about 20 and 35 lbs, short and long respectively. Probably 60 or so for the front diff, and a t-case is 80 - 90, and another 15 for the front driveshaft. That's around 200 or so. If you can think of anything I'm missing in there, please let me know.

If one of the XJs was an earlier one, they were a bit lighter for various reasons. In 95, airbags were added, which adds a good bit of weight to the front end. In 96, they changed a few things internal to the engines that added some weight. The rear hatch went from fiberglass to metal in 97.
