Well you may want to read up on it then.
"There is no load carrying ball joint in a MacPherson strut
suspension. The lower ball joint is a non-load carrying joint,
positioning the steering knuckle."
Positioning the steering knuckle is it's job, like I stated before. Not to carry any weight of the vehicle. I stated I wouldn't lift there (my opinion). Where scotty said is a good place to jack from as well.
