I took a screw $1 slot screw driver from Target and knocked the dent out of the nut, then I sprayed WD-40 all over it. Enjoy a cold beer while the wd40 soaks through 7 years of grime. Take your hubcap/ center cap off, put the car on the ground, get a 17-18 inch breaker bar, and stand on the end of it until it loosens.
