Mike did a strap bolt come loose or a needle bearing get moved out of place around the perimeter if a cap was taken off & put back on. When R&R ing a ujoint both ears on that end of the shaft need to be whacked between the shaft & the half moon ujoint cap with a medium blow w a bfh to align the ears back after the ujoint caps are pressed in so. Test by moving the cross (rear)back & forth in it's plane & the front yoke (front) in both its planes & it should be free & no roughness/binding. How did our joint venture on the carb turn out?. Found out you cant send metering rods in the mail because their machines have a problem w metal even a minute amt in an envelope. We were lucky one rod showed up! they must have figured it wasn't a terrorist device & resealed the envelope & sent it on it's way.

I agree that the circlips were not installed to keep the cross/caps centered in the yokes and also so thatthe rotation cannot push them out. Also is it an apticla illusion or does the left side cross look to have been real warm. (Hot)
Clean it, if it's Dirty. Oil it, if it Squeaks.
But: Don't fix it, if it Works!

Typically something breaks, to cause a shaft to come out.
BUT....
Something like what's in the pic, could be caused by forgetting to put the snap rings on the caps. Without a snap ring, the cap just flys outward under the straps.
I had the u joint pressed in the shaft by a local shop so a)I don't know if any snap rings were there at all to begin with and b) I didn't look for any as I didn't know there ws supposed to be any there in the first place and c) I just put it up on the yoke and torqued the two straps up. uh oh

the two straps and the bolts that held the ujoint to the rear are both in place and tight.

haha, remember Robert, we think terrorist attack all the time here in the Washington DC area...lately it's been from Congress and the White House on we, the American taxpayers.
I gave up on the AVS and borrowed a Edelbrock performer 600cfm from someone locally. Thats was I was testing when this occured.

I think the circlips were not installed 
I just googled circlip to find out what they are.
I DID NOT put any circlips or snap rings on when I put the drive shaft on the yoke.
I just put the straps over the u joint and tightened them down.
Thank you gents for the education and that "learning curve just got another bend" comment is great.
keeps me from being in this situation

The ujoint box contains the new loose clips whether you buy it at a parts store or it is delivered to their shop. The shop should have pushed the clips onto the caps when they did the R&R. & if not they should have gave them to you when you picked up the shaft but there is no reason that they wouldn't have taken a few seconds to push them on the caps to finish the job before the shaft goes out the door to the customer.

I kicked a driveshaft out of my 67 Barracuda once. I had just swapped the 3rd member and used a new set of u-joint straps. Turned out they were for the larger joint. They bolted on fine, but they did not stretch down over the caps, they fit flush without bolts. I didn't notice and used them. I took off down the road and up around 70mph my driver door started to vibrate. I thought to myself, "that's odd, never done that before", just then KABAAAMMM...thumpeta..thumpetaaaa. That sucked. Had the driveshaft repaired,installed with new correct straps, hammered the floor back down (big dent on rear seat footwell tunnel)and hit the road. After that it had a tiny vibe in the upper MPHs. A couple of months later I found out what the vibe was. I pulled off the freeway on a lonely offramp heading for my friends house and while gently pulling away from the stop sign, click, tink tink tink.. Looked under the car and there is the driveshaft on the ground with the yoke and half of the pinion still attached  I'm glad that didn't happen moments before as I was playing with a Camaro at 100+mph. Appearently the original driveshaft pop-out episode caused a fracture in the pinion and it finally gave way. I am 100% certain on what straps I use on u-joints now. That learning curve nearly had a u-turn in it. Travis..
