Took the tail off the ground and did some more investigating. Its not the tail wheel connection but point of note, I did not use the shim. After calling customer service they told me this was not needed with the T3 and ABI tail wheel.

It seems there is movement at the top three pivots. I can see the two side plate shifting relative to one another and the pivots. Im going to call (if they are open) and see if I can get some advice. I oiled everything and still clicking.
