Report Disaster! Rear Wheel Bearing in Mark Jones Blog A blog by markjonesx in General Posted May 25, 2011 When I did my bearing on my '79 S2 years ago (maybe 1990) it absolutely dropped in. I tapped out the old bearing with a socket almost as large , froze the bearing for several hours in the freezer, and used my oven and I believe it was set for about 220 deg F. I was somewhat amazed at the drop in fit. It's been fine since . Maybe the tolerances varied a bit and mine was a slightly larger bore than some others. All I can say is I was there, did the work, and and it happened. (and it wasn't loose after it cooled and I replaced the circlip. ) YMMV.
