This truck has been on the back burner for a few months. I fiddled with the upper control arms some today to get the camber close to spec. so I can take the truck for an alignment. I loosened the nuts and turned the bolts to move the upper control arm away from the truck frame. The adjustment cam on each bolt limits the movement and the camber is still off some. Does this cam need to be removed to be able to get the camber in spec? I assume you just have to remove the bolt and the cam will slide off.

The arrow in the picture shows what I am talking about.
