The rear wheel bearings are roller bearings. Reuse the OEM bearings as they are better quality than the repops made overseas. I have found you can grease the bearings by hand without removing them from the hub. I believe the original grease seals were leather. If they are still good, I would let them be. If you do have to replace them, be sure to regrind the cevel on the big snap ring to make removal easier, next time.
