Look what let go while crusing at 80mph......
Look what let go while crusing at 80mph...... It was the loudest, most evil sounding racket I've ever heard.
Only this 18" long piece of the rear shaft was left. The rest of the shaft was gone and out on the highway somewhere. Never went to look for it.
The front u-joint and shaft that goes into the tranny tail cone was still there....so it broke the shaft there also.
TQ arm was terribly bent.
The end of the piece pictured below is all bent up around the end from banging the **** out of the tunnel, exhaust and TQ arm. But it looks like a clean shear happened......none of the damage from it banging around is anything bad at all, no big deal.
The tail shaft housing of the tranny case cracked open all the way around 360 degrees. So I need a new tail cone end. I hope the tranny itslef is ok...it was just completely rebuilt 2 weeks ago.
Anyone else ever break a steel shaft????

That sucks. Hope it didn't mess up your transmission...other than the tailshaft of course.
Did you have any vibrations prior, or did it just let go? What kind of shape were your u-joints in?

No vibration at all. Just cruising...and bam.
Shaft was fine as far as I know. I drove around all day maybe about 50 miles highway driving mainly.......
I'll get pictures when he tears it apart to replace everything on Monday.

My aluminum factory original shaft from 1998 broke about 4 years ago....it just sheared clean under throttle doing 15 mph through a parking lot.
The pictures you see is what was left connected to the rear-end. About 18". The front 3-4 feet of the shaft fell out when it sheared and is on the highway somewhere.

The front end of the shaft that slips into the tranny......the yoke...was still jammed in there. So obviously the front part of the shaft broke there too. The two caps of the front u-joint were gone that seat into the shaft mounts, and that u-joint was still sitting in that yoke.

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.

Well, all I have is that 18" rear piece. Its a clean shear, it looks like it was cut with a precision saw, thats how clean the cut is.
No way someone could get under there and reach the shaft without lifting the car up, its lowered.

Why....what does it mean if I had vibration first??
I get back from a trip on Sunday....I'll go see if I can find it. It has to still be there off to the side of the road.

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 ?
