When you do lift on retract the Z axis reverses direction very quickly...Is it the sound of the balls banging into each other inside the nuts?

I wouldn't tear anything down- I think that it's a normal sound based on the motion. Inside each nut there are a bunch of balls in a tube that runs from the top of the nut to the bottom. As the screw moves the balls recirculate through the tube. There is some extra space in there to allow the balls to move freely without scraping on each other too much. When you quickly reverse the screw, the balls shift in the space and bump into each other, hence the clicking sound.

One of the axes on my delta started clicking occasionally. It turned out to be a disintegrated bearing on an idler pulley.

I've done it a few times. Keep the whole thing vertical, and spin the nut up to the end of the screw, and try to keep it under control so you can take the balls out one by one. I used antimagnetic stainless steel tweezers to grab the balls. Keep a jar of degreaser handy to drop the balls into as you retrieve them. Putting them back is always harder than getting them out...
