I wanted to close the loop on this thread in case anyone looked at it (annoys me when I see threads with no solution posted!). The sound ended up being the rear passenger side top mount - the rubber has sheared completely so the suspension was moving freely up and down over bumps, knocking loudly. It didn't fall out because of the large washer on top of the damper, but was surprised how the rubber completely failed.

It was a brand new OEM top mount when the suspension went in, but of course the suspension being much stiffer put a much higher load on it.

Thanks!
