So, maybe the system works!!
When this issue first came out, I found my off drivers side lock nut would freely move with one finger. I applied a liberal amount of blue loc-tite and tighten the lock nut after "clocking" each end the same with the wheels pointed straight ahead. I just checked and everything still looks fine. I believe that the ends may not have been clocked the same at the factory and shape turns caused the lock nuts to loosen.
About the "system working", I filed a complaint on safercar stating that RAM fix by welding the lock nuts was not acceptable to me, as this adjustment was intended to be available.
I believe that RAM should be replacing all of these drag links. So I am waiting it out, and physically checking mine from time to time, along with being aware and looking for any changes in steering while driving.
