Also, if you had your front struts replaced, he shouldn't have even had to jack the car up, unless he was replacing the bearing plate and/or spring as well. They come out through the top of the strut tower under the hood.

That's why I was wondering....if you take it apart and jack the car with the top apart for some reason, it'll drop through and you have to jack the control arm while guiding it back through the hole...
There is a correct way and a wrong way to lift under a control arm on FWD cars, they aren't as strong as the old RWD ones. It is not a weight bearing structure, only serves to provide a pivot point for the lower ball joint and radius for the suspension...the jack has to be under the ball joint and centered or it can bend/twist/crimp the arm...
