Update:
So after I found a bit of wettness under the jeep, I cleaned it off really well with brake cleaner. That was 3 days ago and Ive driven probably 150 miles or more since then....and its still dry as a bone. SO...I dont think its a rear main seal...maybe just got wet and dirty...I dunno, but its not leaking, and it never uses oil. So I was just assuming, but I think I was wrong with my assumption. So thats good news.
Here are some updated pics.
