Sorry, I'm trying to read everything here... how can you tell if you have one of the driveshafts that are prone to breaking? I really have no intentions now of taking the girl that fast but would like to know how to identify the shafts before they started replacing them.... I want to know what I have on my girl. I got my car in May of last year so it has to be the early version but wanted to know what to look for specifically. Thanks!
I got mine in Aug of 05, its an 06 model. and yep it does NOT have clips. But the u joint does have channels or grooves in the joint ends outboard from where the caps have been "pressed' in exactly where clips would fit if there were any. I wonder if i can just get a set of spring clips to fit ? Any body tried this?

No, Ford did not change anything. Yesterday the drivetrain on my 2007 Mustang V6 convertible broke at a speed between 100 and 110 mph. I luckily survived and there was not much damage to the underside. I shall post fotos and further iformation tomorow.

Well, there are two reasons to replace the driveshaft now.....high speeds and it will come apart and it does rust. Although, it is not likely that I will be pushing it over 80 mph anytime soon.

I ordered my Mustang V6 convertible (Manual shift) in November 2006. It was produced in January 2007, delivered in Florida in March 2007 and shiped to Europe in May. I consider it a sports-car and I did not buy it for going 55 to 70mph top speed. (There is no general speed-limit on German Autobahns. Supposed street conditions are good, dry surface, not much traffic I frequently go more than 120 mph with other cars.)
My Mustang has the clips but at speeds above 125 mph the driveshaft startet vibrating. So I did not drive faster than 110 mph which is below the factory set speed-limiter. When passing another car at around 105 mph vibrations startet, I immediately deaccelerated, but it was too late, driveshaft blew away.
I took the broken driveshaft to a company specialising in building and rebuildung driveshafts for race-cars and oldtimers near cologne. People there said they had never seen anything like this. As reason for the disintegration they suspect spotty production quality and faulty balancing. They can rebuild it and think they can do a better job than by just having it replaced with a new stock driveshaft. However they are concerned that there is no middle bearing.
As far as I know, the V8 comes with a driveshaft that has a middle bearing. They recommended to put in the middle bearing from the V8 as well as the corresponding driveshaft. I think the V8 driveshaft has a different length, using it would, if possible at all, require some kind of modification to it. Has anybody in this forum any experience/information about this problem ? Maybe somebody can tell me the exact length of the V8 driveshaft and the position of the middle bearing. ( I cannot ask Ford in Germany because Mustangs are not sold by Ford in Germany and not covered by any warranty in Europe.)

I also drive my 06 coupe on the german autobahn. When I read this article first, I decided to change for a pha aluminium driveshaft before setting the limiter off. I´ll install it within the next few days. @roland : I´m glad to hear that you`re not hurt.
Silly question but how does the speed have anything to do with the failure? Wouldn't the RPM's be more the issue? I can't imagine that the DS knows whether it's in first or fifth gear. What were the RPM's when things blew apart?
5th gear usually is direct transmission. 5th gear in Mustang V6 Manual has an overdrive. A common 5th gear overdrive in those gearboxes is factor 0,9 ( Driveshaft rpm = engine rpm x 0,9 ) Does anybody know the exact overdrive ratio in 5th gear ?
