strange noises on y (vCore4 IDEX 500)

Hello, I just finished my build and i am a bit concerned about the rattling noises on the y rails. If you check out this video, you can clearly hear the sound. https://cdn.discordapp.com/attachments/1223286652949106748/1351344121192775853/76394870036__BCFB4BBD-F1A2-47C7-81B4-951331BF2215.mov?ex=67dab189&is=67d96009&hm=689e4d511cd0e2a9ab8777330d20c06b4b9b19e2952d993d8cd67852d1dcc630& you can also see it in the input shaping graphs. x is clean, y is not. I did everythign according to the build guide including cleaning the rails with isopropanol and lubricate it with high performance grease for fast rotating bearings. I hope to find some help here.

I think I ran into this a few months ago during initial tensioning on my 400 idex I also think I backed tension off until it went away. I found during tensioning that I'd hit a point where the graphs would flip on its head kind of like yours after a point. take with a grain of salt tho, cuz i think I have to redo my tensioning again heh
