Can someone tell me if the wheel stud can be removed by hammer and punch. Also, can they be replaced the same or similar way.

I had a loose wheel while traveling and 3 of the studs broke off. The other 2 nuts were on there were loose. I was very lucky as I was traveling down some roads that had very steep drop offs.


If someone can help me with the procedure and give me the size of the wheel stud.)I'm thinking the stud size is 1/2x20x1 5/8ths

Thanks, for your help!
