If you have 4wd the bearing is pressed onto to hub and can't be change. The unit is sold as a whole as a bearing hub. The cheapest I have found it was $171 at autozone. same is true for the 1500 2wd, only AutoZone doesn't have it listed! I had to get mine from the dealer. However, the dealer gave me a 8-lug hub instead of a 5-lug, but it had the same bearing.
