A couple of weeks ago I had a shop install a set of Michelin Pilot Sport AS3 205/50R16 and today I found that they had cross threaded one of the lug nut. The lug nut wouldn’t move when I tried to loosen it. After several attempt with an impact gun and still refused to budge I took out the 3’ cheater bar and the stud snapped. Yeah, what fun!!! Inspecting the wheel hub I don’t see any room to remove the broken stud with a 2 ½ lb hammer without removing the hub. I removed the knuckle, pressed out the hub, hammered out the broken stud, installed a new stud with a stud puller and pressed every thing back together. Here are some pictures that I took.

You did a nice job replacing the broken stud. I guess I have been lucky to deal with a tire shop that always torques the lug nuts when they replace tires. If the shop does it right you will never have broken studs. Using a impact tool to tighten lug nuts can also warp and ruin your rotors.

I would have taken the car back to the shop that caused the problem and insisted they fix the problem.

Most tire shops use torque sticks with their impact gun. The torque sticks will not allow the wheel bolts to be over-tightened. Without the torque sticks, disaster lurks.....lol
