There was a pretty good posting on this subject a while ago. I think a Timken Bearing fellow said "why change them?" He gave reasons for keeping the ball bearings (run cooler, etc.). I've driven my '48 3/4T daily for 9 1/2 years on the ball bearings (max. 45 MPH, though). Of course, if they got completely trashed, I'd consider going to rollers if they were cheaper.
