Centering yoke play

I'm dealing with an obnoxious ticking/tapping sound. I pulled the driveshaft again tonight and inspected. I believe my noise is coming from the centering yoke. There is a slight catch when rotating by hand and I can see the ujoint cap lift out of the centering yoke. Also in the position where the cap lifts, I can easily push the centering yoke in and out maybe 3/16". Here you can see the cap within the yoke and with just a little bit of pressure can easily manipulate the centering yoke in and out

Can anyone confirm that this should not be that easy to move and pull away from the joint?

I pulled out a spare Tom Woods shaft I have, with little miles on it. There is no noticeable play in any direction. This is consistent with the few I've rebuilt also.

Thanks guys. When I rebuilt this driveshaft i didn't notice any either. This seems awfully excessive now, @jjvw thought so too.

I don't notice any damaging signs to the ujoint, but I'll replace it anyway when a new centering yoke gets here.

Took it apart and found a couple things. First, the spring had fallen thru the centering ball hole. I went to pull it out and it was lodged thru there pretty good. I have a greaseable version to compare, notice the hole size between the new and used?

I also noticed the needle bearings were not sitting level. Upon a closer look I found this small metal ring on top of the needle bearings looking a little janky

I carefully worked it out and this is what I found. I am not a betting man but I would bet that this needs to be one circular piece.

I am almost certain that replacing the centering yoke will solve my issue. I can't take it for a spin at the moment because I am missing my tcase output yoke and seal (fixing tomorrow). I will put in my greaseable version and pick up another one later for another spare.
