I believe the adjuster WITHOUT the locking nut is the OEM adjuster. They are an interference fit designed to not use a locking nut. The others are an aftermarket replacement with the familiar adjusting screw with locking/lockdown nut. As mentioned, replace them all with Smith Bros components. Maybe ensure the surface the locking nut will seat down onto is filed down flat so the nut is not forced to seat against an irregular surface.

Smith bros or manton and replace all of them in the correct length. That's what I think. Those look like 1-1/2" and that's too long. Get a set of 1-1/4". And these new ones will have a larger hex in the end. Mo better.

I believe the adjuster WITHOUT the locking nut is the OEM adjuster. They are an interference fit designed to not use a locking nut. And when the interference fit becomes loose, only way to save the rocker is to run a tap through the threads and use an adjuster that needs a locknut.

Thankfully, the mini-me screw came out smoothly. No other sign of buggery, hope they didn't drop the proper hardware into the machinery I'll make that adjuster available as a genuine original MoPar part for that last correct-numbers-and-codes detail Smith Bros to the rescue...

It's the amount of adjuster sticking out the bottom that really matters.
If the results don't match the theory, change the theory.
