My jeep makes a sound from the rear. For example today backed out of a parking spot and a loud clicking kinda like if u put a baseball card in the spoke of a bike only louder. Any ideas of what this might be?

 

Is this the first time it's done it? I'd pull off the rear wheels and give your brakes a nice inspection. Something may have gotten knocked loose inside the drum

edit: I mean, but that's only one possibility. It's VERY hard to identify clicks, pops, rattles, etc. You just gotta get back there and take the entire car inch by inch and try and find what doesn't look right
