Just replaced a TO bearing and hub (as well as clutch & Pressure Plate) in my 52 F-1. The bearings do go out and it usually starts with a whirling noise when the clutch is depressed.
I know you have the others on hand but C&G sells the bearing with a new hub for about $40. . What's the cost for piece of mind? I know you don't want to "do it again" for $40.
Just my 2 cents worth.
