I love you guys but the information you gave the singing woman is way off! The camber on the volvo 240 is adjustable by loosening the nuts on the top of the strut mount in the engine bay. you should have told her to take it to someone who knows what they’re talking about, There’s lots of good Volvo guys out there…
While it’s true that the camber is adjustable in that way, the caller’s issue was caster which is not adjustable on the 240 series.
