If you can turn the adjustment screw and it never stops, the adjustment screw/insert/nut is stripped out, or it popped out of the core support. Like I mentioned before, they fail often, even new ones. I literally have bags of them, that's how many fail for me. One good pothole and boom, done.

Bottoming one out and if you keep turning, boom, done.

The pocket that has the U slot that the screw head groove goes in can also over time get wobbed out, and slip out of the slot. That can happen too if you don't adjust the other adjuster a little if you crank one past a certain point.

I was tempted at one point to even try using a different adjuster setup, was sick of constantly replacing the adjusters. But at some point, the set I have in 3 cars now are holding up, so...

Virginia has pretty good roads, and most don't have crowns anymore. Not sure how much that could impact headlight adjustment but I no longer compensate when having front end alignments done. Have done that for years now.
