Well I thought I screwed the pooch. After reading other threads about people mixing up the races, installing the wrong races in the wrong places, and the importance of keeping the right race with the right bearing, I thought about what I'd done. Last Saturday I had unwrapped both bearings and took both races and threw them in a Baggie and popped them in the freezer. Oh crap!
I came home from work and dug them out of the freezer and compared them side by side. They look absolutely identical to me in every dimension. Crap crap crap!
Then I noticed the part number stamped on the bearings were unique to each one. And faith and begorah! The races were stamped with matching numbers. Whew! Dodged a bullit on that one.
