RE: Len in Maryland, Man needs Darton Help.
All the ' fixes' that you heard are pertinent. Any bow with a module for draw length adjustment is susceptible to coming loose. That would be my first take. The next is the limb to pocket area where ever so slight a movement can cause noise. In this area, lubrication usually solves the problem.
What you seem to be experiencing is something I' ve only seen once - loose limb pockets. There appears to be an incident where one of the impact tools at the factory may have gone out of spec and some bows got out that weren' t tightened down enough. You will find two screws which hold the limb pockets to the riser. These need to be VERY tight. I will have the torque requirements for you later.
