Good point, I know exactly what you're talking about. I'll take a real close look at the bearing and surrounding area tomorrow. .

I hit the curb full sideways so most of the loads were transfered axially, along the axle's centerline. The bearings are straight rollers so the impact was transfered axially through them and then along the outer races seated in the axle housings captured by 4 bolt flanges.

...been there in either case, been lucky more than once.
It was too much gratuitous torque multiplication prior to clutch engagement.

I actually was planning on having a just tad of wheel spin, sort of an explanation mark at the end of a sentence kinda thing. I just wasn't planning on THAT much wheel spin. I've done it many times, although never with those results. I guess it's time to stop while I'm (almost) ahead...

I'd like to but the sphincter spring had everything, including the 8 butterflies pulled tightly shut.



Thanks to all for the well wishes and the OMFGs. It was the combination of a bad choice, some good luck and somebody up there looking out for me.

I know what forces are at play and the resulting consequences when applied. I have pushed my 500 rwhp C6 Z06 daily driver for 60,000 race/non-race miles. The nannies definitely help in it's case though. The short of it; not a rookie but never too old a dog to learn from my mistakes...
