I just did the struts and just signed off on $79 for an alignment. From what I can tell, castor and camber would only be changeable based on how the spring sits in the spring plate at the top of the strut, and certainly no alignment shop will change that. My struts go into the knuckle with standard bolts; there is no slotting or way to change camber based on how the top of the two bolts connects the strut to the knuckle. That leaves us with toe-in, which is changed via a screw on the control arms. I suppose it could possibly change if the strut mount is not aligned precisely as it was initially. Is that all that can really be addressed by an alignment for such a situation?
