Thanks colossus, I'm actually gonna go to one of my dad's good friends and get it fixed. I'm also pretty sure it's a bad bearing because the Tahoe we just bought had the same symptoms and it turned out to be a bad bearing. We'll let you know after tomorrow. I'll also ask where he gets the hub assembly. Have you tried autozone or similar? Not sure if they actually have any but it would be the first place I would go.
