They have no physical evidence that the car hit anything. I'm still being stonewalled by Chrysler. Unfortunately the car is about 200 miles away from home but I plan on dropping in to see the dealer very soon.
I like the idea of getting an independent transmission "expert" to look at the car on my behalf. Thanks for the advice. I'll keep you posted.

From what your said,it sounds like to me in my opinion,is the U-joint(CV)locked(froze)up and stopped turning and tore out the rear housing from thr transfer case.If you daughter was driving on the highway in 4wd low,they would also be putting in a new engine.The gear is so low in 4wd low that the top speed is about 25mph.If you were on the highway,the engine would rev up and would be screaming then blow.So I dont think it was in 4wd low.I hope this helps.

The more I question my daughter about all of the events, the more I learn. She tells me that when the tow truck driver loaded the Liberty onto the platform, the car had to be dragged up the ramp because the rear wheels were locked-up. Yet when I looked at the car in the dealers shop a few hours later, (remember....the drive shaft was laying on the side of the road four miles away from the dealer shop) the car rolled freely even though it was in park.

My brother tells a story about going down the highway in a 60's Dodge Polara with a friend, the friend's dad and his friend's little brother. His friend was in the front seat horsing around with his little brother and the gearshift got shoved into park. His dad instinctively hit the brakes and locked up the rear wheels enough for the parking paul to engage.  The rear wheels were locked up and hopping on the pavement at 60 mph before his friend's dad could get the thing out of park.  The car was unhurt and driven many years after that. Doesn't really help with this issue, but it is kinda funny.

You have a very interesting problem.Unless the rear end locked up,and they didn't change the rear end why would it move at the dealer.The dealer had to do something to get the rear end to move.I would try to get more answers from the tow truck driver,and the dealer.If this was mine and its still under warranty,I would fight this.I think Chrysler right now is trying hard to save money,I'm sure that includes warranty work.Good Luck.

Generally, u-joints lack the ability to stop turning. Being driven by both the engine/transmission and the differential, a u-joint that has bearings in the cups seizing up generally disintegrates the bearings becoming very loose, noisy and out of balance before complete failure. Given the corners that Jeep has cut on the Liberty it seems unlikely that the u-joints are spectacularly strong.
There are/were two-piece drive shafts in some trucks where the central u-joint ran in a hanger with a bearing. In that case the bearing could seize up and something would have to give. There would be lots of racket and warning for a while before this would happen.

We still don't know what happened yet.I know what your saying about the U-joint,I seen that before.I'm talking about a U-joint that seized up, when you take off the shaft hit the joint with a hammer and it doesnt move.I had many of these happen before.Plus I think the joint behind the transfer case is a C/V joint,which I replaced the most on 4WD.It could also be the shaft in the transfer case broke,I had that happen before.That doesn't happen to often.What ever it is,I hope rpizzi can get it fixed under warranty.

I've had a 2002 Liberty that I purchased brand new. Have had the speed sensor replaced at least 5 times. Wait till you try to trade in without a working speedometer... I've had to at least 4 different repair shops and they've been on the phone with Jeep corporate and no one can figure it out... Very frustrating!!!

My dealer told me there was an issue with the routing of the speed sensor cable. It gets caught between the rear suspension arms and the hand brake cable. You can see it (above the differential housing) when you crawl underneath the rear end of the truck.
