Actually, ALL my bearings have been set with play. Been doing it 53 years. I won't be stopping either.
Just checked the rattle on my SA XL-RD5w. It goes 46 mph EASILY. Last week it did 40 on a curved hill and I slammed on the drum brakes.
ZERO indication it's not good. My SA RD3 is the same. Neither has a speck of pitting.
My CCM front hub will spin 3 minutes and rock back and forth another minute.
What HAS shown wear, are pedals that came too tight. There's even more need for them to be a bit loose.
