In my minds eye I am having trouble understanding which way one would clamp the shank, up or down. I guess you want to push the shank towards the top of the receiver? I'm asking because I am interested in this as well. My old truck had less play but it was with a different shank (though thought these things were made the same?). The new truck its obvious because you can see the wear marks on the shank from where its banging around on the receiver a bit.

The real question is, wouldn't using one of this subject a lot of force to the clamp and eventually break it? I can't imagine the clamp being rated as high as the shank or receiver. Or maybe I am overthinking it?
