To free up the ballcups you need to add two or three layers of clear tape to the ball head and snap the ballcup in place. Then remove the ballcup and reinstall it without the tape to check for free movement. Repeat and Add thicker tape until you get free movement...

I have warmed the arm and removed the ball and then made sure it was clean. I have even buffed the ball to be smoother but still no joy. When the arm is warmed it moves better but when cool it is stiff.
I believe the balls in it are the 3racing balls and I have not tried a Tamiya ball. Would this be the solution or is there something else?
