I was at Summit Point yesterday for FATT. During my 2nd heat I had my left front hub fail. It let loose in turn 5-6 or so, and if you know Summit, that's about the slowest part of the track. Which is right after the part of the track with the highest pucker factor IMO (downhill at 80-100 depending, about a 30 degree turn a little off camber and max braking soon as you're through it). So I am OK and there is no body damage.
The hub flange sheared right off, and the wheel getting pushed back it must have bent up either the brake caliper or the slide pins, the caliper doesn't float any more. A guy with a TA next to me thankfully had a spare hub, so I got that on and drove carefully home. This was a Mike Minear hub so I'm contacting him to see if he wants to inspect it. I'll probably get a new one from him over the winter.
I'm thankful that was all relatively low drama. If that happened almost anywhere else on track, well all the other places are pretty high speed, and it would've been a real wreck, literally.

It would be interesting if some other owners of these hubs would tear them down and do some mag particle or dye penetrant to check for cracks. It's really not a good idea as stated above to draw much if any conclusions from the pictures, but it looks like the spindle was cracked for a while. Anyone still running these should use some dye pen to check them.

The thing is, there is a "shoulder" ring that is slipped on that goes right were the fillet junction is from spindle to stud plate area. (You can see it in the pics.) Both mine failed the same way, whatever crack or defect is there could not have been inspected unless that ring was removed, which is pretty much impossible. Sure there could be other cracks, but that is the important area and it's covered up.
