Took apart my SharpClaw and noticed the black stopper for the ratcheting gear were VERY loose. No wonder it felt like there was no ratcheting clicks. Just reinforced the black stopper with krazy glue and let the glue set. Once it dries reassemble the hips and you will be able to hear some ratcheting clicks when you move the hips. It does not totally fixes the problem, but at least makes the combiner mode slightly more stable.
