Or catalitic converter. I know my heat shield was rattling against part of my transmission, but I could only hear it in 1st gear cause it was too loud to hear it what I was going any faster.

Underbody rattle usually originates from the transfer case linkage or a bad catalytic converter. When I had a rattle, it was from a bad cat. I validated the rattle by hitting the cat with my hand and hearing loose debris moving around.

I've been tracking a rattle and I've either replaced or isolated everything I thought of or heard of. I'm currently operating on a theory that possibly the trans mount and/or motor mount is worn and thus causing the T-case shifter linkage to rattle more so that it normally would. I think it's the one bushing or joint specifically. I wire tied it what I thought was tight but still had a rattle. The list of what mine isn't is far bigger than the remaining list if what it could be.

Good luck sorting yours out. I'd check the t-case linkage though if I were you.

Are you able to see the bushing without removing it first? I have a similar noise and want to take a look at this.

You can see it when you climb under your jeep. If you check out that link it shows the location and all the parts. Look to see if the rubber boot is worn off. If I remember correctly the boot has a spring inside which keeps tension and prevents the rattle.

I got under there yesterday. Didn't seem like anything was prematurely worn. Def not the cause of the rattle I have. Mine is really more of a knocking. Thanks for the reply.

I had a similar issue and had a busted motor mount. The only way I found it was while doing the MML. It was unnoticeable from the top.

Well, I decided to buy the kit in the link above to get rid of the knocking noise as I had. When removing the bolts securing the torque shaft bracket, I found one of the bushings on the bracket broken. This was the source of my noise, no the parts in the TSB kit.
I did some searching on an OEM parts site and found the bracket for $90+. Being the kind of guy that would rather find a way to repair this cheaper, I did some more searching around. I found a link where guys ran into the same problem. Someone had the parts numbers for these bushings and I just ordered 4 to replace all the ones on the bracket. So when they arrive, Ill install the bushings and the TSB kit and give it a test.

Link for thread about the bushings. Torque Shaft Bracket bolt bushing - JeepForum.com

Anyway, just thought this might help out someone else out there.
