Rattle from underbody??

[ThatsMrGimp2U]

Guys, I have wracked my brain on this for months now. Imagine hearing a soda can spinning at high speed with four or five tabs jingling around in it. That sounds coming from the floor of my liberty. You can't hear it when its cold and when its raining it get really aggressive. I replaced the joint on the rear of the front driveshaft already. Nothing is leaking. Fluids in my t case and front diff are fresh and full. What in the hell could this be? A friend suggested the chain in the tcase being loose but I don't see how rain could affect that. Thanks for the help!

heat shield?

Either a heat shield over the cats or in my case, one of the bolts sheered off the mid portion of the exhaust right before the muffler (where the two flange-type ends bolt together). That caused to to vibrate and create a very "tinny" noise.
