Default Re: My back wheel bearing exploded!

Loose ball, but leave one out. Check the races for wear, adjust preload carefully then check again for play after mounted on the bike.

In the original pic of the failed bearings, the grease looks pretty contaminated. At the speeds I see some talking about riding I'm surprised this isn't happening more often.
