I cut away the inside of the dust shield to get a look at the inside. I found that the daughter boards had to come out toward the lens. The lens is not glued in the normal manor, it is either sonic welded or RF welded together. Making separation almost impossible.
The parts are not board mounted witch means that there is movement and after vibration and time the solder joint can crystalize and become intermittent if not perfect.
I can get to only a few with the opening I made.
