I actually messed with this a little last night and tightened the bearings some. I suppose there was a little bit of slack. It took me about 30 minutes for both wheels, doing it the first time.
I don't see how the dealer got off saying that both bearings needed to be repacked! Everything was clean as can be when I opened it. Seems like they should just have retightened them for 30 minutes of their time rather than try to charge me 3 hours of labor for a total of about 270 with taxes (they wanted to repack everything)!! I suppose they just would have retightened it without repacking . . . for 3 hours.
