Had a similar situation and it turned out to be a wallowed out bearing seat on the rear left. Even a new bearing could move inside the seat causing a noise as you describe. Sorry to say its eerily similar, Means a new wheel if its the case
Same here.
Although I wouldn't call mine a clunk as much as an annoying clicking sound, every revolution of the tire. I also, among other things, changed bearings and they seemed to fit well.
Mine had chrome wheels on it and it seems others that had chrome wheels had this type of issue. Kinda seems like the chroming process affects the machining in that spot.
Another wheel (not chrome) fixed mine.
