If you think the problem is your shooter is out of balance it should be relatively easy to eyeball the system and see where it is not symetrical about the center of rotation
and to guesstimate the amount of weight you would have to add to the other side to balance it - like they do with the lead weights on car tires.
regarding metal fatigue, I dont think you will see any visable signs until something breaks. After a part has failed an experienced M.E. can look at the break and tell why it failed (crystalized, sheared, cut...)
