Almost 1000 posts and no solution. I'm amazed that we have people that can swap the 2.5L for a small block V8 but we can't solve a noise issue.
Anyway.... I have information to add to the discussion.
When I have 3 or more people in my car, I have the clunking noise regardless of how fast I take off. It's really bad when I start off on a hill. The extra weight really adds stress to the problem. The noise duration also increases as I pick up speed.
clunk.............clunk..........clunk.....clunk.. ..clunk..clunkclunkclunkclunk
That is pretty much 0-35mph^^
