Evidence please that Nippon makes the steel and that Dana is required to
use it by Toyota.

Otherwise, you're making a unproven conjecture.

Not the same material. Similar materials get made in the U.S.

So how does it get to the foundry if no one is shipping it? Ductile iron
is an alloy. The Japanese apparently would prefer to use the same alloy
they use to make the same parts in Japan. And it costs money to ship the
iron ore from Australia to Japan. That probably adds more to the cost
than it does to ship the iron from Japan to US.

The point is that US manufacturing imports both iron and steel, whether
you believe it or not.

The actual report submitted to the NHTSA has not been released because
that agency was shut down due to the snow storm. So we don't yet know
exactly what Dana said. The only news reports are based on the
notification Toyota sent to the toyota dealers.

According to those reports originating from Toyota the defective part
is said to be "joint" in the drive shaft. And the failure due to
"improper manufacturing process control".

How about some proof of that?

Do a search and you will discover Steel in an amalgamate that uses iron.
Iron is brittle.
