What would cause my barely used green bearing to do this?

I love these threads.

"This bearing failed. Mopar Performance books from 90's said it wasn't great for this application."

"You're retarded."

"Jet engines use bearings that are different, used in a different application, so I'm right"

"Angular contact bearings aren't suitable for wheel bearings"

"Punk"

"Dirt"

"Ford"

Man o man, never anything boring in a Green Bearing thread.
