Changed some fluids, etc on the Armada this weekend. There's a skid plate that needs to be removed to get to the oil filter and I ran into a problem. There are four bolts that hold the skid plate in place, 2 at the front that go into what is basically the metal portion of the bumper (also might serve as the lower radiator support) and 2 at the rear that go into a crossmember. I couldn't get the front ones to come out. They spin and feel normal, they just don't back out at all. Going the other way, they don't torque up either. It's like there were nuts on the ends and you're not keeping them in place...except (as far as I know) there aren't supposed to be any nuts and if there were, there'd be no way to access them. The attached photo shows the front of a Titan with the bumper removed. The red ovals show the appoximate location where the bolts would extend through if they went all the way through the bumper, but they terminate within the bumper.

Searching the Armada and Titan boards, a lot of people have problems with stripping and/or snapping the heads on these bolts, but I haven't found anyone with the same issue as me.

Any ideas?
