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

it's really not at all helpful to turn a thread like this into a tapered vs green bearing debate. there's nothing about this situation that would point a finger at the cause being the fact that the bearings were green bearings. hell, if i had used tapered bearings, it may have not even seated into the housing properly for all i know. it's just distraction and noise at this point.

it’s called a chat forum or “discussion” forum. So, what are the issues with tapered bearings?
I would like to know because I went to Green bearings on a rearend and have went through two sets in ~20,000 miles. I’ve had tapered bearings go for 100k. Green bearings might be just fine if all you ever did was go in a straight line. They just don’t last in real world driving , i.e. not in controlled straight line drag racing.
I was sold on the ball bearings because they are “easier” to service but really, there’s no problem servicing tapered bearings. Also, I was considering a brake kit that only works with ball bearings. I asked Cass Eslick about it and told him I corner hard in the car and he said it would be fine. I’m thinking he didn’t consider that people corner their car harder than turning off the 1/4 mile track at the big end. I would have chosen a disc brake kit that works with a different housing end and built the rear with them, like big Ford ends with tapered bearings.

Green Bearing fans just can’t grasp that they do not live in road race, autocross, or even canyon carving road trips. It’s a case cognitive dissonance. “Dr Diff says they’re good, and he’s a Doctor!” , “This guy uses them so I don’t want to miss out”.
I’m not hating on the Green bearing but I am throwing shade at people who think they are just fine in every application. If you’ve got a bracket car and can’t figure out a dial indicator then they are for you OR if you putt your muscle car around town for about 2,000 miles a year then that’s fine too.
