Some good advice has been given. I would take the front diff. cover off and see what's going on in there. It may have been just that the vc was bad and they "thought" that was what they needed to do.
To answer a previous question that you asked about how crud could get in there, if you are missing the axle shafts including the stub shafts then the end of the axle tubes is wide open to allow stuff in.
Good luck and keep us posted.

My advice would be:

- Make sure that you don't have any front axles. You can see that where the axle tube ends.
- Open the front diff to make sure it's not chewed up real bad, look for gear cogs damage and metal shards in the oil, replace the oil.

If above is all good:

- Get some junkyard left and right axles with u-joints (and bearings with them to save the hassle of undoing the axle nut); Even if your diff is screwed you can still reuse these and u-joints are more robust than CV's anyway. Keep in mind you'd need these with tone rings for ABS, some XJ's and all ZJ's came with those.
- Get a junkyard front driveshaft, CV-style.
- Bolt it all together and see how it goes. Listen for noises at 60-70 mph, growls/whine etc. That'd tell if your diff is good or not.

If the diff is good, proceed to VC diagnosis. If not, get any junkyard D30 front axle from XJ or ZJ (keep an eye for ABS sensor hole if getting a XJ axle)
with same gearing ratio (3.55 or 3.77, whatever you've got). If getting axle from XJ, better get a low-pinion version, high-pinion is stronger but requires a 2-3'' lift. Also if you get an axle with u-joint in front, you can replace your front driveshaft with a stronger u-joint driveshaft.

VC diagnosis:

- To a tight figure-8 turns on a dry pavement, look for wheel binding/hopping and reluctance to go in turn in idle. If you see that, your VC in your Tcase is dead. Then you have 2 options:

a) Rebuild your tcase, install a new VC, costs about $400, good for another 100-150K
b) Get a junkyard 242 tcase and swap it in, costs about $200 and good for the rest of your ZJ life.

Thanks to everyone for replying, can't thank you guys enough for the tips and detailed instructions. Going to make sure the pinion and gears are there before deciding what to do next. Most definitely will seek my parts at a u-pull before buying anything new/rebuilt. I hope everyone in Jeepland has a great weekend.

My guess would have been front pinion bearings are shot and he didnt want to hear it roaring... hence taking the axles out and the drive shaft... hopefully it was something stupid like he wanted to save gas mileage and the only thing missing is axles and driveshaft

Still wouldn't hurt to check with the previous owner and see if he can/will tell why he removed the parts, AND he may still have the axles and driveshaft. If the PO does still have them and they're good that would save some of the shopping money and hassle.

Lemon? LOL. Some lousy posts up there. ALL ZJ's need front end and tcase work after awhile. Big deal-NO.

If it was made by a man, a man can fix it.

Don't feel alone, the one i bought recently had this little hidden issue.
Not to worry though it has since been replaced with an 8.8

I dont understand why someone would remove the ring gear and put it all back together @dave seems like alot of work.

On that same note my 93 limited parts jeep had a similar issue i was ably to spin the drive shaft in complete circles with both rear wheels on the ground and the entire time i drove it it sounded like it had a flat tire in the rear.

If you look really close you can see a cut mark in the carrier, they cut it in two places and took it out that way! YIKES! LOL
The inner pinion bearing was toast and the teeth were stripped off the pinion, my guess is it locked up and lots of bad things happened.
The other issue was when I pulled the front cover to check gear ratio, the heads of every other ring gear bolt were broken off. New bolts and some locktite and all is well on that end.

IF he got a niner and teh motor/tranny are in good condition and the body is nice then yea, with low KM, then ya, 2300 would be ok.

but when someone posts up they just bought a jeep without most of the front end in it you assume its a 500$ 'steal'

start hitting junk yards, find the driveshaft and an axle to swap in. easy and cheap if you look hard enough. i would assume a slew of things; if it was the VC then a new driveshaft will fix your problem. might as well do new axle shafts as well. start there. if you have a gawd aweful noise, look to the diff. and look to replace it. if its pinion bearings like others stated, then it probably ran with a junk driveshaft for way to long (and killed it with vibes) or he ran the diff low on fluid and killed the bearings that way. 2 most common ways to do that. either way you need a rebuild or a new diff. i'd go new diff. but all signs point towards poor maintenence.

its still a lemon in my books because of that though. anytime you buy a rig thats missing, umm, the whole 4wd system, you cannot assume ANYTHING was done right/maintained on the vehicle. this is not a 'dick' comment or me ripping on you. thats just the plain truth. the guy who sold it to you was 10x more of an ******* than i could ever be.

get it fixed up and enjoy.

I see both sides on JohnnyZJ's comments. I have to say I sold the daughters 96 Limited with a locked VC, pulled front driveshaft but had to yank the ring gear because it ripped teeth off the ring and pinion before I did the drive shaft. That being said, I sold it for $500 and he KNEW what was wrong with it, because I TOLD him. Driveshaft was on the floor and I offered him the ring gear, he didn't seem to want it missing teeth though. Went in my scrap pile.

And yeah, it's a lemon. So was the 96 I sold, the 97 ZJ, 99 XJ and 02 WJ in the driveway now. Send that one up to the cold snowy north to help round out my collection, who needs AWD in Alabama?

Any updates on axle/vc situation? And I hope the stub axles are in the front wheel bearings if you drive this any time soon.

That sucks....Someone was definately trying to hide something...But you should be able to get a couple of cv style axles for $60-70...Driveshaft you may have to source from a JY or a driveline company...hope that is all it is....I would take the cover off the front diff and clean and check it out before you get to far....You may have a bad diff...
