Front subframe stud removal?

How do you remove the front subframe stud from the frame safely? The one on the car is stripped out completely. Thanks guys.

 

Pics? I mean usually a floor jack underneath and then unbolt. You will probably need some heat on the bolt if the head is rounded. Then hammering on a 1 size smaller socket then remove.

 

No pics at the moment but i tried hammering on it with a small sledge with no movement. It was welded in the engine bay so i cut that weld down and put an impact on it but it just cracked the weld and didn’t turn.

 

They welded it? Oh man, that is messed up. And I am guessing you got rust too?

 

It’s a factory weld and the rust isn’t to bad but i was able to find a bolt and washers and use the only section of threads left on the bottom to hold it up for now. I will be looking into further before i reinstall the front bumper.
