2188 Popping noise in rotor

Has anyone ever experienced a popping/cracking noise coming from the rotor? I've noticed this sound when rolling it slowly by hand, and have concerns about the source of the noise. Any suggestions would be appreciated.

The front bearing shaft can be loose in the rotor tube and/or the rear drive hub has broken bolts.
