I just replaced the struts on my vehicle from a pair I brought from the junkyard and went in for an alignment, the shop then told me that my left wheel has 2"30 degrees of camber and the only way to fix this issue is by "opening" (translated from arabic) the strut, not quite sure what that means. Now I have had the exact same issue with the old struts before and the camber was fixed by doing that. They also told me at first that they thought the issue was with the used struts but after remembering that the car had the same issue with the old struts the problem seem to be with the car itself.
Now my questions are, what is causing this excessive camber on the left wheel? Is the only way to fix it is by "opening" the strut? and what exactly is that?
The vehicle in question is a 06 Chevorlet Aveo with a single control arm type suspension
