So I don't know how well you can make it out in this picture, but my Grimlock has one weak tooth on each of his arm ratchets. It's the equivalent tooth on each side which is at least better than having different weak spot for each arm. I've bought other Grimlock's to try and fine one that doesn't but each time they've had a rounded tooth on one side or the other and somehow having it on one side feels even worse. Is there any way I could build that tooth up if I unpin the arm? Or evem turn the shoulder into a friction joint?
