Did a muffler shop recently remove rear wheels to work on exhaust?
you're right jack.
studs cost just $5 a piece.
I guess it's my fault for buying the impact wrench and for being so over zealous with it.

You can bet it is WAY more than the 80 foot pounds specified.
I actually had one of those neanderthals tell me the extension he was using limited the amount of torque he applied. BS
Now I just take them the wheels and tires and do the rest myself.
The chrome on my lug nuts thanks me.

No Black ones rule.
and the stud failure is why I always tighten by hand and never with an impact.
I had an 83 chevy 4x4 when I was growing up - big tires - big lift kit
had both front tires shed 3 of the 5 lugs & studs on each side. We determined that it was from over tightening with an impact and then the tires were slightly out of balance because they were mud tires. They started popping like popcorn and the whole front end was shaking violently. Pulled over and had to be towed home. It was scary - kind of like the time I broke an axel.
