What you describe is very reminiscent of when I cracked the pinion gear on the rear end in my old S10 Blazer. I am not saying it is that it could also be the drum for your parking brake. Best thing you can do for self diagnoses would be to jack the back end off of the ground and put the trans in neutral. Try and spin the wheels to see if you can feel/hear when it clicks. Then if possible have a friend listen to see if you can get an approximate location of the sound.

When I finally got around to doing mine I found 3 teeth laying in the bottom of the diff case. What led me to the diff was the ticking sound which originally made me think drums. Well ticking became a clunking and ended up with severe jarring when the flat spot would hit the ring gear.

Not saying this is what your problem is but just giving out some info to see if it helps.

Same thing I'd do. Jack stands first, spin the tires, check the ebrake, then pull the diff cover.

Thats good news, at least it wasn't a big money repair. Rear end noises can be difficult to pinpoint when driving as it is, so many things that can make similar noises.
