I still don't understand this one. There must be thousands of Chevelles out there that have turned 4000 rpm in high gear (1:1) many times on stock driveshafts. Munice + 12-bolt = stock length shaft, right? The factory offered 4:10s which would put the driveshaft at that speed barely above legal posted speed limits. I wonder what was going on in your car that made it spit out the shaft?

Not a Mopar and not a Tremec.

I'll post up the details once it's here.

John, at this point all I can conclude is that the shaft was junk from the beginning. That still doesn't explain why the 2nd shaft also had a vibration (out of balance or warped also??), but at this point it's water under the bridge. All I can do is pick up the pieces (literally) and move forward.

That was actually my first choice, but as per a call directly to Richmond yesterday, that box won't be available until July at the earliest.

The part that confuses me...it came apart under no real load. At what RPM would this have failed on the ground with traction /weight and increase friction-resistance in the driveline ? It could have been much worse. How much depth was in the yoke engagement, how did it slip under rotation? Could there have been a bind adding stress to the shaft during torque / suspension cycling? Any clues on what's left of the Muncie or the shaft (tubing, wall thickness, cracks) itself?

I enjoy doing Destructive & NDT testing on Welded-Fabricated components here at work....I find all failures interesting as they each tell a story. I'm looking forward to seeing this back together !
