I had a noise problem while drawing the arrow back several years ago that was bugging me . I thought it was a wheel or cam or slide . I discovered that it was the arrow (aluminum) scraping the prong rest where the rubber coating had worn through .
Since then I have gone to drop away rests and carbon arrows .

Have someone with good hearing stand next to you while you draw your bow and see if he / she can pinpoint where the noise is coming from .
