NonOEM bearings are a heck of a lot cheaper and are just as good. Contrary to what the dealer and most auto parts will tell you the old bearings can be pressed out and new ones in, the whole hub doesn't need to be replaced. This will save you at least $300 even if you have a shop press the bearings. Sorry I don't have the part number of the bearings only, but they are rather common from any auto parts or bearing house.
