Yes and no. If it was aligned with a fairly worn ball joint in the past then installing a new upper ball joint will change the alignment. Changing out your upper control arm will change your alignment unless you get it back to where the old one was exactly, which could prove difficult since you typically put in new bushings and upper ball joint which will be way tighter than the old worn out stuff. Your camber is adjusted at the upper control arm bolts and your toe in is adjusted at the tie rods. The holes that your upper control arm bolts are slotted and the bolts themselves are flatsided on one side. This causes the upper control arm to be adjustable because you can change the overall angle of the vertical axis of the tire with this adjustment. There is no other adjustment on the front end without modifying the factory type parts with aftermarket (Offset bushings, etc.)
