Seems some Magnum axles are breaking. http://www.lvvta.org.nz/do***ents/i...6-2012_'Magnum'-brand_Axle_Safety_Warning.pdf
Wasn't there just a 32 that was wrecked on the way back from Bonneville on here that had a Magnum axle. Pretty sure it was and took a damn good hit without breaking so maybe its just certain batches?
Mark the day down, Moefuzz worked in his 2000th sbc dig into someone else's totally unrelated thread. RPM there has been a great deal of discussion on here on those particular axles and the jury is still out. While we've cases where they have broken we have also seen the one on the Deuce that was in the wreck this week that bent and didn't break. I'm still going forged, either dropped original Ford or SoCal.
This is really a sad situation. I have never been afraid to run any aftermarket axle or any other component for that matter, but I have to say if I had any Magnum axle on my car it would be coming off. I can tell you from experience (from having the aftermarket steering arm on my Son's T bucket break in half at speed in traffic) that things can get real bad real quick. If someone from above wasn't riding shotgun with me the night it broke I might not be typing this now. I realize any supplier can have a certain percentage of failures, it just happens, but when it comes to stuff that can kill or hurt you, then it gets real serious. Don
A bit more discussion on here. http://www.nz-hotrod.com/vbulletin/...eam-Axle-Safety-Warning&highlight=magnum+axle
The LVVTA (Low Volume Vehicle Technical ***n) was set up by hot rodders for hot rodders, we were heading for a complete clamp-down on home made cars here in NZ, so a few good blokes decided to take matters into there own hands and the end result is we don't have many cobbled together pieces of **** on our roads, yes even the r@$ r%^$ have to be built properly or they're not allowed on the road.

Per, we have quite a fewe threads detailing this. But thanks for bringing it up. Maybe Metalshapes can combine them at some point?
Just a note on this, if you read all the do***entation. It seems that the problem is with one shipment of about 500 axles produced in the 2008/09 time frame. Canuck I know it had me worried until I read that.
the problem is all of them wouldn't have been sold at one time, some may have been on shelves for years, some may still be unused somewhere, they aren't like a carton of milk that expires, I always thought that any type of critical suspension parts like thought ought to be required to have serial numbers, if they had this could have been resolved quick, At the minimum a batch number when castings are made
Although cast parts of good quality should be safe to use, I'm getting more and more reluctant to buy/use them. A steering joint more or less exploded on my car. I thought it was forged, but it sure looks like it's cast. Fortunately it happened in my garage, while testing the steering standing still. Don't want to think about what would have happened out on the road. And in case you wonder; no there was no binding, no extreme angles and the axles where the right size for this application (3/4" double-d).
Had the same problem with a straight coupler I bought,my son in law hit a bump and curb at the same time, it jerked the wheel and he lost the steering.Shattered the coupling.
Correct it was our car that got wrecked....I was in the car when the wreck happend and the axle bent all to hell but did not break see pictures here... http://www.jalopyjournal.com/forum/showthread.php?t=726627 I for one will be buying more magnum in the future should I require one Sent from my DROID device using the TJJ mobile app
it's not all of them,it's a certain batch made in a specific time frame, there was a major issue with a batch of 500 castings, the problem is no one is exactly sure where all of those 500 castings are
While everyone is crying over broken aftermarket junk axles... I'll keep using the axles forged at River Rouge without any complaints.
Why in God's name buy a cast axle when you can just as well buy a forged one? This is the reason I bought a CE axle three years ago when considering a dropped front axle for my current ride.
Funny how that pdf says a thousand words in 5 pages and it doesnt even give an actual reason why the axle snapped. I would think that there is a reason why they decided that batch was "faulty". So, what do you think the reason could be for such a faliure? High percentage of x contaminat in the steel b4 fusion? Or something to do with the heat treatment?
Discussions about broken aftermarket axles happen fairly regularly here. I haven't noticed anyone talking about breaking an original Ford axle. Does that hasppen? If it does, it apparently is relatively uncommon?
They break but you got to work at it. Anything can be broken some things just take more stupidity than others. Very seldom but it does happen. If you go back though the pics on all the threads it is almost always the same axle. Take a minute to check it out. I think if you check this thread we have already discussed this article from down under. http://www.jalopyjournal.com/forum/showthread.php?t=721791&highlight=sema
I don't get why anyone would buy another Magnum axle, you are basically playing Russian Roulette. Since there are no batch numbers, how do you know that you are not getting one of the **** ones from 2009?
"The final reports, based on a microscopic ****ysis of a highly-polished cross-section of the material, showed that the failure was caused by a fault in the casting process, either from using the wrong material (such as normal grey iron instead of the proper spheroidal graphite [SG] iron otherwise known as ductile iron or nodular iron) or a fault in the casting process such as pouring the material at too high a temperature." As quoted from the article................
My guess is a lot of guys aren't going to get theirs checked out, but will just replace their Magnum with a forged one and try to sell the Magnum at a swap meet. Be wary of used aftermarket axles from now on. Blue
