The castellated ring screws in to compensate for wear in the ball and socket (sort of) system.
It isn't uncommon to find so much wear that there is still quite a bit of movement with the ring screwed all the way in.
Also, the wear in the joint can be uneven, so you get tight spots and loose spots.
Dismantling them, you may find packing that helps to alleviate the problem - string, bits of tin, etc.
I think mine are done up to nip but not jam, and then stuffed with thick grease on a regular basis.
