Chevrolet and GMC light trucks have plastic hub caps held on by decorative fake nuts. Being plastic, they crack (which means they can't really tighten) and sometimes they fall off. I lost one. Forrest happened to find one somewhere that had fallen off someone else's truck. We put it on the Rolling Steel Tent, but it fell from its new home, too.
So, in the spirit of maximum wheel balancing, and not wanting to spend about $30 on a new set of hub caps, I removed the fake nut that was 180° from the missing one. Naturally, the little suckers fight you when you want them gone.
I wouldn't be surprised if the remaining six fake nuts thought, "Why should we have to take up the slack for the two who've gone AWOL? Screw this. (Or unscrew this.) We're out of here." That's when I'll feel like spending $30.
