Hi JRouche,
That's a good education there, thanks for the tips.
It's prompted me to go back & have a look at the HEX material. I checked all the way back to the importer and received some assurance that it was meant for truck wheel fasteners, which can handle both torque and pressure. They also guarantee that the steel is as strong , or probably even stronger than the type use in the standard ball joint. ( Grade AISI 1035 - 1037 )
And I also did check the set up , things are as what we have installed. I will contibue checking as a routine .
On the HOW it was made. The " Spacer " is tapered inside with threaded to fit the standard pin , then this spacer was tightly screwed over the standard one , plus with safety pin inserted to prevent the unscrewing movement.
You are right that when we deal with this type of work the main concern is the safety espect, and that is why I didn't use the naked ball joints even they look more exotic but prone to wear fast.
Cheers,
GM.
BTW the certainty in this small world is hard to find, see the below pic of a damaged spline shaft, which passed through the hardening process and yet...has gone south !
