I know there have been plenty of bolt removal questions on here, but here goes. The lugnuts on the front of my XJ are @#$#ed. I was able to get 4 or 5 of 10 off no problem, but the others wouldn't budge. These seem like really crappy lugs, not one piece but two pieces with the nut and a cap. I've sprayed PB and tapped on the nuts every night for about a week and a half. I've been alternating between a breaker bar and impact wrench, and basically I've succeeded in breaking off most of the caps and stripping the nuts. The nuts don't seem to be stripping like I'm used to, it's more like they deform, like they're made of lead.
