Having just come to this thread, I apologize for any repetition.
I have been under our 2009 Roadster, with the camera as it is almost impossible to get at the plates due to the Chassis & Exhaust. (after 12500 Miles)
This was the best shot of one side I could get (I Know Dave. Its a mess down there) Now I am wondering if there is a crack on the left side just below the Bolt head?
Looking at these Roadster pics taken in 2011, I cannot see how a Rutherford Conversion would fit without having a whole new Upper fixing place to bring the whole Damper inboard of the Chassis? (however I have not seen one to compare).
I also do not know about 'Axle Wind Up' and its effects but would have thought that with the axle being inside of the 'castings' partially controlled by the Drive Shaft and U Bolts any twisting torque would be taking place inside there?
To me the angle of the Dampers to the axle is totally wrong for the 'Arc' or 'Vertical' movement of the axle as it is held by the Leaf Spring. There must be side ways forces coming into play, if not on the suspect plate, on the Damper Rod?
Whatever the cause it is not a happy situation. I shall ask some questions during our R100 Group Factory Visit on Monday.
