GVDocHoliday,
I wish I would have seen this sooner.........my Patriot Dually was doing that exact same thing, and it turned out that all I had to do was take the modules out, clean them up good and put them back in tightly.
Seems that if you get a tiny bit of dirt wedged in there anywhere if you are swapping out modules or get the cams dirty, it can cause a tiny gap that isn' t visible to your eye, but when you draw the bow the force of the string/cables applying pressure causes the module to " pop" slightly as it completely seats itself.
A simple removal, wiping down and reinstalling them has taken it away for good.
Just a theory, but since a simple cleaning took mine away I have to assume that is why at least I had a " click" .
