Well, I'll attempt my best @ diplomatically playing both sides. At first glance, from a logical engineering perspective, ford dropped the ball on the V6 shaft. A hollow shaft with the CV essentially in the middle, is going to get out of wack @ some RPM. Now what that RPM is and whether it is the owner's fault for exceeding the limitations is somewhat debatable, that's all I have to offer. I WILL be uprgrading my DS in the near future just for peace of mind. Is Ford expected to do anything really though? Why would they recall/change it? A large portion of V6 drivers report the apprehension of exceeding 115 , or tracking their car on a stock DS...please? AFAIK the stock DS is sufficient unless the you exceed the 115-120 mark......then an aftermarket option is on you.

Since you asked, I've hit over 115 plenty of times in my vehicle. No vibrations, no breakage. *Knocks on wood.*

Here is one example, y'all should use the search engine and educate yourselves.

You've cited 1 example -- from almost a year ago. Where is there a recurring issue (i.e. a defect, a design flaw, not a 1 in 20,000 fluke) that Ford needs to step up and fix?

Sorry but failures as a result of structural integrity ARE going to happen more often when limits are pressed, not in everyday conditions

Show a recurrence of these failures under normal operating conditions and I will be the first to retract my comments

NP Cannonballer, I haven't bought my replacement DS yet either, doing wood floors in the house right now, and my gun hobby is slowing down the process too. I have a big discount through AM, so I may get theirs, or maybe the new shaftmasters one. Can't afford the best one, DSS is a bit over kill for my application and budget.

My concern about the driveshaft failure is my own opinion.I have had friends of mine driveshafts break and it's not pretty.Some on the Dyno,some on the street.

I never once said to go 2 or 3 times the legal speed limit.Here's my point.As time goes on and people race these cars at the drag strip or road course this becomes a saftey issue bottom line.

But clearly from this ^ post you affirm that you are talking about about driving at racing speed, legally or not.

And if you (general third person you, not you) are going to drive your car at excessive speed and beyond its design limits, then safety is YOUR responsibility.

I am not going to attempt to compare the physics of a rotating dyno drum to a stationery road, and please dont try to argue that the planet is spinning under your wheels in the same manner as a dyno.

Dude it takes 30 seconds to search, here is another unmoded forum member during normal driving. No mods, no racing, no dynos. There are several more if you want to find them. But I'm sure you won't, and I'm pretty sure you won't retract any comments either.

Looks to me like a beefier driveshaft is not necessarily what Ford should concentrate on, but improved QC inspections instead? Perhaps select one out of hoewever many produced in a particular cycle and wring the thing ragged, to make sure tolerances aren't slipping during the manufacturing process? What about the steel that's being used? Is it all coming from the same source? If so, is that source being regularly checked for contamination? I don't know if any of this even applies. I'm just thinking of my younger days as a plastic molding injection machine operator. QC inspections were endless. Find even one drop of oil contamination and the parts go bye-bye until the contaminants are purged and nothing but clean product comes out. You'd think there'd be something similar in place for these DS's? Maybe corners are being cut somewhere? Who knows?

How Many? I posted another one for you just like you asked, and I've found more, if I post those will retract your comments? Nope. Why do I waist my time...

Thumbs up

Jeff, you're a true aesthete/kindred spirit if your gun hobby is interfering with your car mods. With me (20,000 rifle rounds loaded on a single-stage 1989-2006), it's the other way around. Damn cars.....

How many have failed under normal operating conditions?

How many who "said" it happened under normal operating conditions were being forthright and not scapegoating Ford to get out of being responsible for trashing their cars at excessive speed?

I would think if this was anything but isolated incidents there would be a news story somewhere on the web, but there is not. I could not find even one

Im pretty sure American Muscle had a stocker shaft break on them while cruising down the highway. Granted, their car isnt stock (at all), but no 'abuse' was taking place at that particular moment.

And speaking of abuse...

2012 Mustang 3.7l v6- 1/8th mile racing against 3vs + others - YouTube

2012 Mustang 3.7l v6 1/4mile runs- [email protected] - YouTube

2012 Mustang 3.7 m6 v6 dyno-279whp 270wtq - YouTube

Those dyno pulls reached 142mph 3 times....

::::KNOCK ON WOOD:::: I guess Im a lucky one. Still planning on upgrading the shaft, eventually, but Im still a skeptic on whether its the shaft itself, or whatever's causing the vibration thats likely busting the shafts....

Is the TC trying to run for office or something? If other people want to push the stock DS to the limit, let them. No need to get all hyped up over why Ford did or didn't do something... If you don't feel it's safe enough for you, go get a new one. They're really not that expensive compared to the catastrophic outcome of a driveshaft break otherwise, are they?
