No - the rear can be either two bearing/race sets and a spacer, or can be a single sealed unit. Either way in every case I've seen, the rear is sold as a unit - per wheel - while the front is sold individually. You have to buy four bearings for the front, and two for the rear. 4 seals per wheel all the way around. They are a different size than the front, are held in differently, and the seals are different. I don't see the similarity other than they are both bearings. Have you ever done one? I've done enough to own the special tool for it....
