This is a broken fulcrum pin from my car.

As my friend with a Phd in failure analysis says: 'Every pin no matter what
its composition will
fail in this application. Its not a question of if just when. When it
fails
the crack will progress at about 600 ft/sec. Considering the pin is only
3/4
in across, it does take long for the pin to break thru. Unfortunately the
cracks are usually hidden in the A-arm sleeve. The pins have to be removed
and
maganfluxed and microscopically checked. Even doing this will not guarantee
that just after you reinstall the pins, that a pin will break backing out of
the
garage.
