On the other hand, they will all come out with the right persuasion, so do not give up on it.

I second that emotion. You have to really want to change the bearings over to a cartridge to justify the work and frustration. IF you get it wrong, it will put you way behind the eight ball.
All things considered, I would change the gease and the bearings and keep it the way it is. Them old bearing cups never hurt nobody. Leave 'em be.
