I knew it! Them damn Heim joints should have been banned centuries ago.

A properly sized on constructed heim joint is every bit as safe and strong as a bushing.  They aren't used by OEMs due to NVH issues.  Now, from what I've read there are some States, and some applications in those States, where heim joints may fail you on an inspection.  There is no Federal regulation I can find which states they are illegal.  They are included with lift kits which are street legal all the time. 

When that article popped up as part of my search results, I only clicked on it because the website name appeared legitimate being AutomotiveSimple.com. But if no one has heard of this before, I guess I got suckered into a click bait.  Sorry.

The real question:
Would the fact they are banned keep anyone from using them?

Insurance payout would be based on the type of policy you have.  If you have a bare bones policy to try and keep costs down, then they will do whatever they can to avoid paying anything.  However, comprehensive I'm told covers everything, even your own stupidity, so I think they would pay in that case. 

I also think that to avoid being sued any company selling a suspension component with heim joints would include a disclaimer that its not intended for use on public roads, racing or off-road use only, etc.
 

I don't know about the use of Heim joints on automobiles, but they are used on hundreds of places on aircraft flight control rods, pushrods, and support rods. They must be okay, but then rods on aircraft aren't exposed to high energy shock loads either.

You have to post it at least three times and post it in all caps, then its true.  At least that's what all the political geniuses in the world think...
