I have found a new culprit that causes a tick or creap on drawback. I found the bezel on the center pivots can cause it. I had a creak in my new guardian. I looked at everything. Even lubed the axles Finally I decided to totally disassemble. But I started taking off the bezel, and the thing was on there way too tight from the factory. I had to strain to remove. I was always told by bowtech and bowtech staff not to overtighten them but snug. Anyway, I heard the creak as I was loosening. And then I snuged it up and no more tick or creaking noise.
