Gtsum2. You do understand it's not on a ball I assume? I get their concern, however the normal stresses and torques of pulling a trailer up a steep hill and stopping seem to be just as much as the possibility of twisting that square insert. I know they are concerned that the designed pivot point could fail and twist the square pin, but the likelihood of that is very slim I think. Just my opinion.
