Top hinge:
There is a very slight amount of play in the hinge. Maybe a millimeter.
Driveshaft/Bottom hinge:
You can see how the u-joints are wearing on the edge of the sphere. I suspect that to be the issue. It's not limited to the front or the rear shaft either. When I disconnect one or the other it will still stall. Need a temp fix. I'll probably put some different shafts in entirely. I've always had great success with the MIP stuff. Might have to customize something to fit.
