Surly Hub Implode
HI
I was riding my Salsa 'Roll SS home from work last night and as i came down a hill in North Sydney the rear wheel locked up and sent me skidding down the road to a stop. I managed to free the rear wheel by turning it backwards but 50M down the road it locked up again and this time the wheel was all loose and moving around on the axle. Wife to the rescue. This morning I took the rear hub apart and boy is it in a mess. Looks like the bearings have eaten the alloy hun to bits. I've stuck the pics online for you to see. Link here>>>

Do you guys think I'm up for a new hub or is this fixable?
In the shots you can see where the bearings have embedded into the hub and caused little craters but I'm unsure if that is the bearing surface or not. Is the bearing surface further out and where the bearings have eaten the hub just an internal part of it?
I've owned the bike since xmas. Warranty job?
Any advice welcome..I'm glad it was the rear that this happened too. Imagine if it was the front!
OH it's a freewheel HUB for a single speed BTW..

The area with the craters can't be the bearing surface. That has to be steel and IME the balls would shatter before making indentations like that. My guess is that the cone adjustment slipped enough to let some balls fall past the cup&cone and lodge up against the softer aluminum further inside. But I'm unable to determine where that bearing surface actually would be on the pics.
I'd say it's a warranty job, and that it means a new hub to get it fixed.
