Personally, I just loosen the U bolts and the top draw down bolt, pull the hitch head off the cradle, pull the release handle, and lift the bottom cradle part (with tube attached) out of the socket.
I reinstall the same way- just make sure that everything is lined up so the tube is all the way in the socket, and the release handle/crossbolt fully seats. I torque the draw down bolt to 40 pounds per the directions, though I go a little more on the U bolts.
My trailer used to seem to buck back and forth somewhat when stopping, but after I switched to Brakesmart, it stops very smoothly. I think before it was more a matter of the trailer brakes not very well proportioned to the truck brakes than flex in the hitch...
