i broke 2 studs on my car, replaced all 4 last nite. it was my first time doing it, and it took way too long. the way i did it was to use a lugnut and air impact to pull the stud in, but it didnt pull them in all the way, there's still like a fraction of an inch, like 1/16th at the most before it butts up flush, id like to know what the technically correct way of installing these studs is, (for future reference), thanks for any input.
