Hi Rpm
I think Peter is referring to the connection between the support bracket and the chassis. I had ferocious judder when I first put the RK together. Then I found that you could move the whole support bracket up and down on the ball. The big nut on the base of the support bracket needs to be tightened to ensure no vertical movement.
Regarding the big castellated nut tightness. The ball section of the torque tube does tend to wear in one place and it is difficult to judge how much to tighten the nut. Too tight and it can snag damaging the tube. If it is very slack you can remove the support bracket an shave a small amount off the face (1/16”?). The castellated nut should then tighten up a little more.
Cheers
Howard
