[Fot] Spit/GT6 diff stub shafts

[Scott Janzen]

I’m assuming the bolt got inserted to get the remains of the stub axle out of the differential?

So, in over 10 years of racing my GT6, I have never sheared a stub axle (just jinxed myself).
The engine puts out about 200 hp. 
That said, I know others who have had this problem repeatedly. They finally gave up and installed a Subaru differential.
I’m really not sure what differentiated my outcome from theirs. I’ve run mostly a welded diff but also a limited slip.
I’d suggest the following:
Pick up a handful of stub axles and get them all crack tested. I don’t mean with dye- take them somewhere that can magnaflux them .
Secondly, you might try getting them cryogenically treated. I just had two sets treated that way, along with the ring and pinion - those I have had repeated failures on.
Let us know what you figure out!
