Is my rear differential stock?

Definitely not saying the Dana 44 couldn't have drums in 03-06, just that I had never ever seen them on the forums or on Jeeps for sale.
You have now. My 03' was on forums and for sale. ;)

Thanks, I going to adjust them as oldbuzzard suggested. My hand brake gets tight when I pull it but maybe I need to adjust the star wheel first. I can get some pictures later, It is interesting learning all of the configurations the TJs came with.
