Thank you for sending me the freehub body but it was loose rear spokes making the clicking noise on my bike. I have two friends with Rooks and tightening the spokes solved the clicking noise on their bikes also. It only took a half turn on most spokes to cure the problem. My crank arms also are making a occasional snapping noise and I need to tighten them also. Overall the Rook is a very nice bike. Thank you.
