Rear end clunk!!!

Well the honeymoon is over at 20 miles.
Started hearing the clunk towards the end of my ride the other day.
While sitting still if you rock the rzr side to side there is a loud clunk coming out of the drivers rear, I removed the shock, still does it. Greased all the zerks still does it.
I seen in other non 50" threads where people had similar problems but most of those were not diagnosed as sitting still.
Anyone one with suggestions? since popo wont pay for diagnosis if nothing is determined to be wrong.
Going to disconnect the rear sway bar tomorrow see if that changes anything. Sound like its coming out of that region, or maybe the cv joint.
