Found it!! I went to camp jeep over the weekend and i was talking to one the engineers (Jim) so he came out and took a look. Its the t-case linkage, the tension isnt as tight so its making a noise. he said its nothing to worry about, i could replace it but its so rusted it would most likely break. He mentioned that he's seen people put a spring on it just to give it some tension so it wont rattle, so i could try that.

Jim was very helpful and says he really enjoys talking to people about there jeeps, good or bad. He said he's been developing wrangelers for the past 9 years and took a big part in developing the rubicon.

Thanks to all who replied to help. and i'll get some picts of camp jeep up soon...
