So I guess every OEM ball joint breaks at the pitman arm as well?
Show me a dual shear pitman arm please
LOL, I figured I would get a response like that. Tie-rod-ends are engineered to be single shear. Show me a factory single shear rod-end. And don't tell me its a cost at the OEM level. Its not. TRE's are far more expensive to manufacture than a rod-end.
That taper was in your pitman arm for a very good reason. And, please keep an eye on that bolt, so you don't kill somebody. I am not going to argue with you. But I am telling you, its not safe. (but, neither are factory chevy tie-rods on your era truck. I have a friend that can put his truck in 4x4, and bend the factory tie-rods by launching the truck from a dead stop. so, touche' I guess? LOL)
I am actually trying to help. I'm not nit-picking. I really like your truck. And I think you did one helluva job on the SAS! But honestly, spend some time on the net doing research if you have to. If for some reason you don't believe me. Or even better, post a picture over on racedesert.com of your pitman arm, and ask: "is this safe?".
(FYI, I have been building trucks for 30yrs friend. The easiest thing for you to do right here is take my word for it)
Regardless, I will say it again, NICE TRUCK!
Some advice if you are going to leave it as is:
If the bolt gets loose. Replace it. Its probably not because the nut is backing off. More likely that the bolt is stretching.
And use an all metal lock-nut rather than a split lock-washer. The lock washers can break, and fall out.
If this was the tie-rod we were talking about, and you weren't running misalignment spacers, I would have never said a word.
Its the height of the misalignment spacer, and the reduced bolt shank dia. that compromises that set-up. Not the rod-end.
