Last week someone was oh so kind to take my hub caps from my factory directional wheels. Of course, they did not take the one that was missing the brushed aluminum cover. A week or so before this happend, I noticed another explorer with hub caps that had some sort of allen wrench securing mechanism. If I remember correctly as well, they were factory wheels. Does anyone know of something like this. By the way, Ford wants $34 a piece for new hub caps.
