To add to that if a 14-16 has an actual failure the dealer is to contact star for a fix
That's exactly right!
There now may be a thousand -AB suffix revised drag links "in the system" as another poster suggested. But there are ~800,000 trucks that should have the upgraded part!
With those numbers as context, FCA's decision to not allow dealers to order the -AB suffix draglink unless/until they have a truck down for failing the B checks does make a lot of sense. FCA apparently wants to save the few -AB parts they have for available now for those trucks that have
demonstrated issues with thread engagement.
For the rest of us "lucky" enough to pass the A checks, FCA apparently hopes the weldment will keep the draglink from experiencing the catastrophic separation that leads to total loss of steering control.
While I agree with FCA's triage and -AB suffix part allocation given the numbers above, I still think that the
as manufactured thread engagement on this design is at best sub-optimal, and very likely to be out of tolerance for the specified fit. I can't evaluate the internal threads on the turnbuckle without destructive testing but the male threads on the mating part look very much undersize or "washed out".
So my 10K mile new truck might well be relying on the (dreadful, see pics previously posted) tack welds to keep the turnbuckle & draglink
connected and not just to keep the jam nuts from coming loose.
