camber adjustments in general are not easy to make. with struts, it usually requires drilling out the top holes in the strut mount. with most vehicles though, camber is set at the factory with no method in place for future adjustments; you take what you get.
i would recommend getting your vehicle on the alignment rack and see how far the camber actually is. if it’s only 1 or 2 degrees off, then break out the grinder and have at it. if it is several degrees off, then it is something more serious. an inspection of the rear suspension and struts would be needed in order to determine what (if any) corrections could be made.
you might be able to machine the struts/add shims somewhere to bring the camber back out.

So last week i did my first alignment on my own vehicle, 2003 crown vic cvpi. did a perfect toe adjustment. get it off the rack and it drives straight as an arrow; however, my steering wheel was about 45 degrees off lol. went back a couple days later and did a total toe adjustment and it came right back to normal. not sure what happened, but this time i paid extra close attention to steering wheel position.
