Not sure if recommended or not but I have drilled a hole into the thread of the towball just below where nut tightens up and after full tightness have inserted a split pin. Reason why, I have been called to some road accidents where a tow ball nut has partially come loose and stopped with rust or dirt build up usually towing horse floats , car trailers etc with constant braking/acceleration deacceleration over time the metal is fatigue and snaps the tow ball off. Even with safety chains a nasty accident does occur. I have used this method towing caravans all over oz with
the nut locked into place.

some of the accidents i have heard of concern horse floats, where the timber floor has rotted out and the horse has gone through the floor while the vehicle is in motion, the driver has no idea what is happening, i leave the rest to the imagination.
The nut on the ball should be applied with a spring washer so if it comes undone its due to operator error, ie not tightening properly, the split pin will not stop the ball snapping, only stop
the nut comming off the thread. col
