All parts for rear bearing replacement have arrived. One has to be replaced even if new. Two Moog rear bearings were ordered. Part #512226. I opened the first box. I was happy to see Germany stamped on it. I opened the second box. It has China stamped on it.
Not pictured are two new axle nuts.
andrewynn, now I understand why you mean inner and outer races. The hub actually has two bearings. Each side can spin independently. The Germany stamped bearing shows a nice gap between the races. It's stamped FAG too.
I'll probably wait a few more weeks. The hum is not bad enough to stop driving it. It will be warmer by end of Feb and March.
