Anyone had issues with ABL where one Z axis side moves more over time then the other

In my case one coupler was ringing. I fixed it with your tape method. But the squeak on the rod was still there, whenever the Z axis came down. I now consider that to be metal-on-metal noise.

Just had the issues again and it seems the nut came out of the trap. Something I over looked so thanks for the comments. I checked the rods when I pulled off the panel and they look find but may just order more rod for some backups.
