Regarding sealed bearings: a good friend of mine from my days at Motorola Automotive was the mechanical engineer on the alternator product. He is still amazed at how little grease is required to make the bearings live. For example: the front beaaring in an alternator is a sealed bearing with very little grease. It lives a very long time at high speeds in the underhood environment. Pretty amazing, I think. The axle bearings run pretty slow by comparison. Say with most tires they spin about 750 revs/mile so at 60 MPH that's 750 RPM. The bearing is spinning at 375 RPM; no big deal.
