One of the many things I learned doing alignments that need to adjust the 3 is set the two that control the camber and caster to max load so the cams don't have to push the load of the vehicle on the little tabs...those can get flattened out...I've welded them to add strength in some in the past from being destroyed...maybe look at the cam bolts and make sure the tabs are not flattened...If they are ok, then each move of each cam bolt must be very small, camber, caster and toe set at the same time...I know sounds crazy but if you try to set each one individually it won't work and you just chase your tail...I've trained many on this and is very hard to get until you try each one a little at a time...you can't set toe after...It will change the camber degree...it is strange that the specs are different on everything on the printout too...I rarely go by specs anyhow because the window is to big...I set mine at 0 with the camber which is more important than caster...usually caster is at 2 or less...depending if it's stock or lifted...toe is 0 too...and I always go by tire ware as well on lifted ones to see if it needs changed ot tire pressure is high or low.
