3 of my 4 lug nut studs popped off on the front passenger side of my car. How much should I be looking to pay to get this fixed? (I live in Boston by the way) And is this hard to do on my own? I looked at the rotor with the tire off and sort of have an idea of how to do it but I just cant see the back of the lug nut stud, as if I hit the stud with a hammer I dont know where it would come out. And help would be appreciated.
