Look what let go while crusing at 80mph......
If it ripped apart at the middle and had a short vibration prior to it would mean the shaft exceeded the rpm it could live at for it's length and diameter..
But the break you have is not of that issue, you have a issue where it was caused at one end or the other, and the rip was part of whatever broke at the front.
Was a joint changed recently or something played with at the slip yoke ?

Clearly a shiny aluminum shaft.

So they changed the joints just before that failure ? the issue was at the slip end, if you can find that end it'll help
I'll try to find it when I get home on Sunday, it should be there.
But he did say that the two u-joint caps in the front at the yoke that go into the drive shaft mounts....were gone. The two caps were gone, the u-joint was still there on the yoke. Maybe the bearings in one of those caps seized and broke the drive shaft mount.......????

Verdad Gallardo When my factory aluminum one broke back in 2006, the race shop that I got the used steel shaft from told me that it came out of an M6 car and that all M6 cars came with stell ones.......I guess even speed shops are clueless about the cars they work on....lol

Well, this is exactly what happened to me this weekend on a dyno.
The thing that really drew me to this thread was the 80 mph part. Reason being is because at 80mph and above on the way to the dyno my car made a hell of alot of vibration. It also had a poly trans mount on it and that may have been part of the problem.
I got it on the dyno and BAM tail housing cracks wide open and she is puking all over the floor.
Im just asking what in particular do i need to replace in order to keep this from happening again?
do i need a new drive shaft? u joints or what? I'm definitely ditching the F***ing poly trans mount for sure.

Update.....
My tranny guy (friend) called me about an hour ago. No damage to the tranny that he can see. He threw in another steel driveshaft, new bell housing, shaft seal and a new (used) factory torque arm....and went for a drive. Says its perfect.
I got lucky for sure. We'll see how the next few days go. Hopefully no leaks.
I know...get a real torque arm. Getting an adjustable one with crossmember mount.

This is correct. All SS autos had 3.23s, therefor all SS autos have aluminum driveshafts.
I was just making a statement that I SHOULD get a better torque arm to go along with all of my other mods.
Imagine if a stock torque arm could cause a steel drive shaft to break while cruising at a steady 80mph........

not entirely true ether lol, my 00 t/a ws6 came with 6 speed and 3.42s and has a steel shaft lol : \
Every manual car I've ever seen had a steel shaft. I've never seen one with an aluminum.
.
Im sure it was more common to see on m6 and 3:23 autos as when those cars were ordered the dealer was selecting performance drive line codes and many so happened to select the aluminum drive shaft rpo its been that way since the 80's
