Looks like you may have cracked you transfer case housing. No way that front driveshaft should have enough travel to pull apart, and even then, that wouldn't 't leak any oil.

Your front driveshaft has simply pulled apart at its slip joint and odds are it can be put back together. That said, that's extremely uncommon so the bigger question is how that could have happened. Could someone have replaced the front driveshaft before with one that was too short for your TJ's configuration?

The good news is you might be able to drive it if you completely remove the front driveshaft including the front part still attached to the front axle... providing the driveshaft wasn't pushed back into the transfer case hard enough to damage it. And from the looks of the leakage under the skidplate, serious tcase damage looks very likely.

Judging from the oil under the transfer case, my guess is something was damaged there allowing the drive shaft slide back.

I just bought a used driveshaft in great condition for $75. Got a great condition used NP231 transfer case for $250 (some might even say that was a little high!). Then I bought the upgraded U-bolt style yoke kit from Quadratec for around $150. Relatively cheap for parts if that's all you need. Labor will be another story if you can't do it yourself.

Also, I would do a fluid drain and refill on that transfer case while it's like that. Never know what junk might have gotten in there, if any at all.

Good luck to you.

The front driveshaft has a fixed yoke on the transfer case. The transfer case either got damaged from a shock coming through the fallen driveshaft , or possibly had a failure that allowed the driveshaft to pull apart . That oil all over the ground is related to your bigger problem.

My guess first too short driveshaft over extended when axle dropped and came apart then short piece of driveshaft on TC with single joint at attachment point flung around enough to damage case to point of leaking fluid

Just got back from the mechanic. Half of my transfer case is demolished. Hey say I had to hit something for it to happen and I'm at fault. I think I would notice something hitting me hard enough to break my transfer case or bend my shaft. Never been rock crawling. The dealership said I probably hit a curb and it caused damage. I have 33" tires I m not going to bottom out on a curb. Sorry for the rant but it pisses me off. If I'm going to be blamed I would at least like to have had the experience of doing it. Got quoted 1500. That's with a used tcase, new u joints, and a reshaped shaft, oh and oil. And that includes labor

T-case r&r isn't hard. You'll need a jack and a spare pair of hands at times. Only pita is the bolts against the tub and that's depending on the tools you have available.

First of both ends of driveshaft still appear connected in photos one to transfers case and other to Diffy, the shaft clearly separated in middle probably because it was to short and the expansion portion pulled apart. The drive shaft was too short for the application ( lift ect) the prob did not start at the transfer case because the shaft end is still attached and half the transfer case does not appear to be missing in the photo

As for whose fault who ever either installed too short a drive shaft or made the shaft too short by adding a spring lift or spring spacers increasing the span from Diffy to tc effectively making a previously adequate drive shaft too short is who started this ball rolling

Are those stock control arms on there? If so, I have never heard of a stock front driveshaft being too short regardless of lift height.

If he is saying you hit something because the shaft is bent his is wrong. Shafts almost always bend when they come apart while a vehicle moving. If the too short shaft was in it when you bought it it should have been caught in the inspection.

I think I would take that angle and explain how this could have gone very wrong causing injury, etc. I'm assuming you bought recently from a dealer.

that's what I was thinking. And the damage to the tcase would have been caused by the shaft being jammed into it going 60mph and then being dragged when I was pulling off to the shoulder. I did just buy it recently I believe last week for 6k

1. Get a second opinion.
2. That's waaaaaaay too much to pay to get it fixed. A 231 and driveshaft can be found relatively cheap. Swapping them isn't very difficult.

alright I'll ask around. Might just have my dad help me swap. I don't have 1500 to drop. He Said the tcase would be about 600 and the unjointed 15 each and he said the shaft was discontinued to it would have to be taken to a shop to get in bent.

Used tcases are available on craigslist for around $300. New driveshaft from tattons or Adam's driveshaft will be $300. Pretty cheap and easy repair.

Look at the forums and craigslist for used parts. You'll be surprised at what you'll find. I built my JEEP with all "previously appreciated" parts. A transfer case should run you a couple hundred, and a driveshaft should be MUCH less.

Good luck, man. If you lived closer, I'd give you a hand.

All that said, try to figure out what caused this. How long have you had the Jeep? Where did you buy it? Warranty?

perhaps someone used the shorter auto shaft on your manual tranny setup

I can't find anything on craigslist here in San Antonio tx. If I can do it myself do I need to respin the tcase? The mechanic was saying he would have to do that
