Help Broke a lug off 420SEL - PeachParts Mercedes-Benz Forum

Bought the car a few weeks ago nice day so I changed oil and was going to check the brake wear. 4 lugs came out ok but real tight then the last one pounded for about 10seconds then snap. It would be ok if it broke at the wheel. But it didn't.

Any help on how I can get it off. The wheel will not come off now. Bad deal.
It is bad if some idiot uses a high power air wrench to put them on. As it seems to have been. Thanks

No advice, just a question - it broke between the hex and the flange that holds the wheel on?

This is a fairly common problem.

There is a tool built that drills the remaining portion off. You might call around to a few MB specialists and see if they have dealt with it before. I Imagine they will have. Then put your other lugs back on and take it to them.

Either that or buy the tool. You might try www.baumtools.com

Yes that is where it broke. I use a high reverse torgue air wrench to remove. It left the shoulder holding the wheel on. It is a 90 420SEL . People that use air wrench instead of torque wrench should have there nuts tightened with an air wrench. One post said hole saw still looking.
