Photos from another forum. Someone bought this aftermarket Chinesium CAST axle for their rod. I guess it was meant for "garage queens" and "trailer queens"

Someone looked up the alleged supplier. They are claiming it is "ductile cast iron." I'm thinkin' even that is a lie............

I wonder if that came from Speedway Motors? The sell tons of stuff like that. Of course they don't make it, but still, they are a vendor.
 
something we all don't know is if the installer drilled out the pin hole?

I had a forged section of a draglink break cause the machinist did not fillet the corners where it was turned down for threads. So forged parts CAN break when not machined correctly.

Speedway was mentioned. I have no idea...............
 
Imagine if that happened at 130 MPH at the strip.
Next time you press your brake pedal, apply pressure very lightly.
 
Hollow? Ductile cast iron...they are out there. Forged tube axles are $40 Cheaper?

Zig's Street Rod - Suspension - Front Components


I-Beam Axles from Zig's street rods.
Cast from high strength 65-45-12 ductile iron, Super Bell's I-Beam axles are designed to accept '37-'48 Ford passenger car spindles.Applications include '28-'34 Ford, 1/2 ton Ford trucks up through 1941, and '35-'36 Fords when you split the original bones. Split wishbone kits and instructional sheets are available.

Imagine that on a 1/2 ton truck....~!

Looks like their directional tread tire was running backwards too.
 
That looks like a assembly error like someone said tread is going the wrong way if they can't put the tires on correctly I wouldn't trust anything else.
 
Too many things we don't know just looking at a picture on the internet. Could have 50k miles of abuse on it, been installed with a 10 lb sledge, just hit a massive pot hole, who knows. Could also be a bad design, or an inclusion in the part when cast and was a straight up part failure. Or yeah, drilled larger than was manufactured, toleranced incorrectly on install, or modified. No way to tell without the history (which the owner may not be fully truthful about, especially on the internet) or a full on metallurgic investigation looking at the fracture lines, inclusions, etc.

Doesn't appear to be a recent install based on the dust boots.

I mean sure, buy good parts. But there's literally hundreds of different reasons this could have happened that wouldn't necessarily be the manufacturer's fault. And hundreds of reasons why it might be the manufacturer's fault too.

On the other hand, when was the last time you saw a Model A Ford axle fail?

Depends. Lots are modified for applications like this and those absolutely fail because people do it wrong all the time.

Like I said, nowhere near enough information to blame the manufacturer on this. Or the owner or installer, although there is definitely evidence to show that some things on that car have not been done the right way.
 
King pin looks rusty also. Loose and beating the inside of the axle.

Yeah there's definitely a few things evident in that picture that are, at the very least, not best practices.

And let me be clear, I'm not trying to defend import aftermarket parts. There are definitely bad parts out there. All I'm saying is with the information we have in this case there's no way to tell if it was a manufacturing problem, an installation problem, an owner modification, poor maintenance, or just straight up bad luck.
