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

Have you called Dutchman ? I have Dutchmans with green bearings in my Swinger but havent put many miles on if yet .
My Barracuda has Mosers with green bearings and I have around 20k miles on them . No issue so far .
I got them from drdiff, but I don't remember exactly what specs or don't have the order form from it since I think I did it all as a guest user. It was a few years ago also, otherwise I'd ask him. They were basically big bolt pattern upgrade axles. I certainly don't want to blame him or any company really until I know what I'm dealing with measurements wise. Maybe something is off more than it should be.
