Yeah those little guide pins that both these guys listed are what you're missing. They're just pressed in, I've got 2 that are loose and trying to come out. It happens when someone tries to crank the cam/control past the point where it's stopped up against those pins. I bought some Belltech alignment cams for my truck when I dropped it and found out the hard way that the sweep is completely different and won't work with stock arms. I pulled one of my alignment cams straight out of its mount lol
