"Ball joints
The front UCA ball joints are the only adjustable ones. All others are pressed into the arm.
The factory UCA ball joint allows about 1o of change. To alter the setting you take out the bolts and rotate the shell 180o. It’s not much adjustment but it may be enough to get into spec.
Moog Problem Solver ball joints are slotted for camber adjustment. Loosen the bolts, set camber, and tighten the bolts. (Other brands of replacement joints may also allow this. Some simply duplicate the OE joint.)
The pressed in ball joints may also be tack welded. The weld must be carefully ground away before pressing out the joint."
copied from "The Ogre's Cave" Body and chassis- suspension - control arms.. Hope that this helps.. I would replace your front ball joints with .."Moog Problem Solver ball joints are slotted for camber adjustment. Loosen the bolts, set camber, and tighten the bolts."
this would allow the alignment shop to set the camber exactly where it should be..
