Adjustable strut rods making terrible sound 74 Swinger

A "squeak" and a "rattle" are caused by two different issues. Squeaks are generally caused by friction, two parts sliding against one another. A rattle is caused by something intermittently hitting something else, two parts coming into mechanical contact and then separating. Both can be caused by a loose part, but it's two different issues.

You're thinking about the QA1 strut rods all wrong. The double adjuster goes through the LCA, the shoulder of the double adjuster sits against the LCA and the nut on the other side sets the tension of the shoulder of the adjuster against the LCA. You can literally install just the double adjuster by itself with the LCA on the bench and torque the rear nut and never touch it again, it's not part of the adjustment process. Now the strut rod barrel spins on the other end of the double adjuster and the jam nut sets that. But the shoulder of the double adjuster against the LCA is unaffected, only the torque on the nut changes that tension. And properly torqued that double adjuster will not move or spin and it certainly shouldn't rattle unless it's completely loose.

Based on your description, I seriously doubt it's your strut rods making that noise. But since you changed everything in the suspension at once, you will have to through the entire suspension one part at a time to figure out where it's coming from.



I didn't say I knew what was making his noise. But he doesn't have any idea if he has the same problem, and he shouldn't assume it's the same as the OP's because their descriptions are completely different.

You certainly have no idea either, just like you don't understand that a teflon lined heim joint that's under tension shouldn't make any noise. Once again, just because you can't do it doesn't mean it can't be done. 100k street miles with adjustable strut rods, and mine don't make noise. And they shouldn't.
Come to the north east and see how long that teflon lasts.

Heim never made good teflon ends. They are very old and Teflon was the future. If you have heim ends they are old and they rattle. and squeak. Ballistic ends are good and there are other good Rod ends but all are different quality. Heim is a cheap rod end. They are throwaways and they rattle and they all squeak after some miles. some squeak when installed.
