Bad wheel bearing?!

Hi all
Last week my 69 dart started making a loud howling growl inside the car.
It was hard to tell where it was coming from.
After putting it on a lift to check it over I spun the driver's side wheel and it was noisy.
Took out the wheel bearings and found small shreds of metal on the inner bearing.
Cut it apart and found the inner race torn up like this?
Has anyone seen this before?
These bearings are only 2 years old..
