Adjustable strut rods making terrible sound 74 Swinger

Ok, you have no idea if you have the same problem. The OP has a squeak, not a rattle.
OK, based on his comments sure sounded similar to my problem, except for the squeak vs rattle.

And here’s the deal, torqued properly the 5/8” thing shouldn’t matter. At all. Not even a little.
Tightened to spec, same rattle. If the QA1 strut rod end fits into the LCA loosely, then what does it tighten against to keep it from rattling? The strut rod shoulder presses against the strut loop on the LCA and the head of the bolt from the other side is all that it tightens against. Sorry, don't understand that. I will admit ignorance here, but I tried working with it and it just did not get happy.

If you have installed QA1 and PST strut rods, changed nothing else, and had the same noise with both, it’s not the strut rods. The odds that two brand new sets of strut rods, from different manufacturers, with different designs, make the same exact noise is just about nil.
I actually replaced everything on the front end at the same time, including getting Dr Diff front disc brake spindles & calipers. There is a little rattling from the driver side but most comes from the passenger side. As the OP said, bouncing the car does not produce the noise. In my case, when the car is in motion at low speeds I hear it. Coming to a stop the car sounds like a rattle trap. Everything seems tight. Verified the brake pad tabs were firmly against the caliper slide so they would not rattle. That was the first thing I checked.
