OK, I finally got around to doing this. Where's the bearing exactly? Shadowkn, you make it sound like there were multiple fans used by Microsoft in these xboxes that had the bearing in different places? I peeled back the sticker on both sides of the center of the assembly (the sticker that faces the gpu, and the sticker that faces the DVD drive) and could find nothing but flat plastic. I lubricated a normal computer fan before this one so I have some idea what this is supposed to look like I think.
