This is what can happen when the spinning drive shaft says " I'm out of here" There was unexplained vibration that was not found.
This happened to a ratsun member outside Portland near Canby. The bolts connecting the tranny flange to d/s came loose and fell out finally letting go. The 521 coasted to a stop and the resourceful owner used short lengths of welding rod to stitch it together. The A type shifter was also damaged and was held together with vice grips. He limped into Canby from I5 (about 10 miles?) in 1st gear for replacement bolts.
Assuming a 27" tire on the truck, 4.375 diff, 4th gear at 50 mph, the drive shaft was spinning over 2,700 RPM!!!!! That's a lot of stored energy.

Re: Check you nuts if you want to keep them!
woah!
this is also very important in the IRS cars.... 4 more sets to check, going 3-4 times faster!
everyone should do regular nut 'n bolt checks that include the u-joints.

Mike, do you know if the guy this happened to had the OE driveshaft bolts (bigger shank than the threads) or if they were just threaded bolts from HD? It seems historically the hardware-store bolts come loose much more frequently.
The original bolts aren't available from Nissan, however they're also available from any '80s Subaru with AWD. Same bolts.

Re: Check you nuts if you want to keep them!
If we learn ANYTHING from this site, it is that of constantly checking the bits and pieces that keep our cars together, specially the drive train.
In the spring, I was doing my regular nut and bolt check, and I see that one of the c-clips on my half shaft universal, was backing it's way OUT!!! I am constantly looking at my drive train, as we have seen that failure is usually catastrophic. Things go through such heating and cooling cycles, it is imperitive to monitor all the time.
In the picture, you can see the shiny sliver of the c-clip, as it moves it's way PUT.
Take your time, make it a regular thing...it may save you some grief down the road.

Re: Check you nuts if you want to keep them!
Clip backing out...... mmmm maybe that's why my manual says to replace them. I do when replacing the joint as they come with the joint, but have sometimes taken apart for other reasons and just reused them.
Very good point Julian. I'm sure the un-threaded shoulder is stronger too. These are form a mid '80s 720 4X4 and are huge.
