I have no idea. All I can say is that I didn't put different cones in. I pulled out the axle, cleaned everything as well as I could, put in fresh marine grease and put this same axle, with the same cones and all, back in as well as I could.

I performed essentially this same procedure on the front wheel of this wheelset and this worked out very well. I've also repacked other rear hubs successfully before so repacking this wouldn't be a first time for me.
