I don't know. That pic that I posted looked suspiciously like yours, though. MickMate originally posted it, so he knows more than I. Personally, I can't remember the last time I heard about a half shaft failing. Stub axles, yes, but not the half shafts themselves. Now ERA goes to some extra trouble on their half shaft. They shorten it, neck it down, re-weld it, dip it in the river Styx, and some other stuff
. Supposedly to make it "fail safe" -- but who knows. The stub axles have always been the weak point, but when I was there looking over both the plain Jane and ERA rears they assured me they were both good to 600HP, which I don't have, and you don't have. It would be nice if there was an easy way that you could just call somebody up at Shelby and say
"hey, were the stub axles in my wheels sourced from the same vendor, and at the same time, as the differential stub axles?" Honestly, though, if it were me, and considering that right now you have the engine, transmission, and rear out of the car
, I would go ahead and replace the stub axles in the wheel with stronger ones. Of course, you know you have to phase the universal joints on both sides of the differential so all four of them line up evenly else it will vibrate.
(that's a joke, when you think about it, you'll see why....)
