Jeep has 6000 miles on it, five trips on trails, 3 intermediate 2 mild, and I find that my T-case is cracked! I have an 07 Rubicon and been fighting with the dealer since. I took off the skids yesterday to see the issue, and discover the case is cracked. Brought it to Jeep today, who state that would warrenty it, so far that is, you never know. Just an FYI. Too bad I cant get them to give me the cash for it and throw an Atlas 4 speed in there!
