Upon further review, it appears the sound is coming from the idler wheel area. It' s very hard to define, but when I started messing with the slide with my hands, it made a " click" , and I could tell it was from the upper limb area.

I' ve examined the limbs all over, can' t find any sign of hairline or any other type of cracking. Bushings appear fine, no wheel lean or anything visually out of the ordinary.

At full draw, when I look at the idler, it looks like the string is coming out against the left side of the wheel groove as opposed to straight down the groove. I don' t know if this is the cause of the sound or not. The bow is shooting lights out, repeatedly to the point of aim assuming I do my part.

I need to verify and fix the source of the noise. Any other ideas? I plan to call Diamond tomorrow. I' ll ask them about new ' 04 bows while I' m at it
