We bought a 2010 Jeep Liberty last year this time. The wife said it was making a noise, that I couldn't hear. Winter came and the windows went up, no one hears anything. Spring comes around and I hear what she is talking about and I could see nothing amiss, sounded like a brake issue...Fast forward to yesterday. I took it to the dealer as it has a full warranty. I had jacked it up and listened and the best I could tell was a transmission issue. Guy test drove it, put it up on the rack and listened just as I did, down, up, down, up, etc, so I knew it wasn't something simple. Came out and said "I was checking the fluids in the trans and it is fine, but when I checked the transfer case nothing came out. Not one drop of 75w-90 that is supposed to have a couple quarts. It looks like it has been dry from the assembly line."

He filled it and checked for leaks and there are none. This has never had 1 drop of anything under it and it is parked in my garage with a clean floor, so I notice everything.
So I have never touched it as it is under warranty = wasn't me. We bought it and it had 15,xxx on it, it now has 27,xxx on it, so the last guy could have screwed the dealer he traded it on. That still means the t-case went over 10,000 miles with 0 fluid.
So, I get a new one, but is that not completely messed up? I don't see how that could happen, it should have exploded in less than 1,000 miles. Let me know what you think. As if this was the old dana 20, NP 203, NP 205, or NP 208 it would have been toast long ago, I don't know how these newer T cases are made, but apparently pretty well.
