Not A-Body: PT Cruiser Suspension Noise

Hoping someone that has a PT might have run into this issue and can point me in the right direction.

My wifes PT makes a clunking noise up front when rebounding off a bump. Doesn't do it when you hit the bump only on the rebound and most often when going through a dip in the road.

I got under the car looking for something obvious and thought I had found it. There is a cast aluminum strut that goes between the sub-frame and the engine. The connection points on booth ends have rubber bushings, it's there to control engine motion. Well the front bushing had torn and the center and the strut were no longer connected and the end could move around a lot. I replaced the strut but it did not fix the issue.

I used a pry bar on all the other suspension bushings but everything appears tight. I felt I had narrowed it down to worn struts that were topping out. Last weekend I installed new struts and felt pretty good that I had fixed it since the shaft would just fall into the body of the strut when the strut was up right. But on the test drive the clunk was reduced but still there.

I had run into this once before and it was the bearing in the top mount of the strut that allows it turn for steering. In that application the part of the mount that bolted to the inner fender was not loaded by the spring. On the PT that pivot is always under load by the spring so I can't see that being the issue.

Anyone got any ideas?
