Who's done them?

My '10 RF linkage bearings are feeling "notchy" when I removed the shock and cycled through the travel and after partial dis-assembly ( I have one sweat-seized al fastener that I'll probably have to drill out ). Fortunately, I can't discern these bad bearings when riding.....yet.
So I'm thinking of replacing all 8 of them ( 4 linkage, 2 CS, and maybe the 2 ABP ones)
Anyone done this? Any trouble finding a bearing source other than OEM? Tips on stubborn linkage pivot/fastener removal?
