I am hoping to get under the Trailblazer this weekend and change out the fluid on my rear differential. I remember seeing that some used their gasket over and some didn't. Anyone have any insight into this? Just want to make sure before I take it off and can't get to the parts store. Thanks

Just remove the old one, clean it up, and replace. The important thing is to spray the bolts on the differential with a penetrating lube. I usually go around and use and extension and hammer and tap all the bolts to try and free them up beforehand.
