The current design of the "joint-8-socket-frica.dat"-primitive is not correct.
If I measure it correct, I find that:
1.)
It should be possible to move the towball ~+/-35 degrees in the horizontal plane.

2.)
And if the axle on the towball is placed in a vertical position, it should be possible to move it ~+/-5 degrees.

3.)
There should be a gap between the backside of this socket and a brick placed on top, or bottom, of it.
It isn't big, about 0.5 LDU, but easy to see.

I'm working on a rewrite, from scratch, if you don't mind, Tim.
Maybe someone could help me and verify my measurements?
