Your best bet IMHO is to take it to a bowtech dealer and have them figure it out.
It might cost you a 20 spot or so, but they most likely have seen it before and will know right where to go with it.

I own a reflex that was doing what you described and the fix was lubing the axles. It didn't have bearings, but I'm not so sure your 02 does either.

My current Patriot did need it's limb pockets lubed, but that noise was most of the way through the draw cycle and wasn't a click.

Good luck and makes sure it's gone before you go hunting. That reflex's noise cost me a south TX ten point in the very early morning calm. From then on I always draw my bow (before season) in a closet w/ the door shut to make sure it's a silent draw.
