I have an 02 Patriot SC. Recently, about half way through the draw cycle, it started making a loud clicking noise from the lower cam. I cant see anything loose--when I have some one else draw the bow, I can't see what is causing it. Much too loud to hunt with(not a problem till August) but I'm also worried something has worn out and am afraid of a failure. Any of you bowtechies seen or heard of this before? Thanks in advance.
