Anyone know how to replace the studs for our cars? Went to my friends friend to buy his used tire because I didn't want to buy a new one because I was gonna get a new set of wheels. So my car was running for a good 30min. To get to the place. Right away he worked on it and it seemed fine but car was hot (so wheels were warm too.) He used an impact to remove the lug nuts. Finished the job. Paid him. 2 weeks later I tried to take off the nut but it won't come loose. I knew it was gonna be stripped and I was right. The thread looked like it melted. Maybe from mounting the lug nut when it was still hot and did it in an angle way with the impact gun? How much does this cost to replace? Or any site I can go to, so I can do it?
