GT75Z,
Something is wrong with the hub or ?. DON'T KEEP BEATING ON IT. STOP!!!!
Questions if you don't mind. Was the race that you so much trouble removing seated all the way down? Did you look at the hub after you removed the race? Was there any burrs? Even the smallest of burrs will have to be removed before installing the new race. My suggestion is: remove the new race, check for burrs gouges, out of roundness, mike the depth & ID of the hub. Mike the same things on the OLD race, same messurement? Mike the same items on the new race, same as the old race? Same as the hub? Most auto stores will sell, let you barrow or even rent a mike. If you get a digital, then you don't have to worry about how to read it. Write down the item you are miking. Write the specs down as you take them.
You have something REALLY wrong. This job is not that hard, yet for some reason it is giving you ****. I suggest that you start over and look at everything with new eyes. If you used heat you could warp things depending on how hot they got.
Buy a new bearing, get a good quality one. YES, there are quality differances. Thats one reason some item cost more then others, sometimes it's just mark ups. Buy the best, work the least.
Can you send some pictures of the hub, the race (old and new) and show the messurements of all those items. Colse ups, or the ability to expand the pictures would be great.
