Help for a Stripped lug?

The proper way is to remove the lug bolt and replace it with a new one. You wil have to remove the wheel, caliper and rotor. Knock out the old with a hammer, then use a nut and spacer to pull the new one into place.

The proper way to fix it is to remove the hub and pound out the lug and replace it. you can purchase a new lug at most automotive stores like Napa, Auto-Zone, Pep Boys... If you don't want to do the work yourself an automotive shop sometimes even a tire shop will do the work and it is not that expensive at all

If it is the outside threads then you won't be able to get the thread chaser or die to start. Try a thread file.
