Atlas,

To narrow it down, I'd take everything off the bow and then add one item at a time. Take off the sight, the grip, quiver, No-peep, stabilizer, even the rest if it may be making noise. add things back one at a time starting with the stabilizer. With the string off, check the cams. Make sure there is no play. When putting accessories back on, I highly recommend putting a layer of mole skin anywhere there is metal to metal contact.

Good luck,
