BigO1120, do you have any update on yours?

I noticed the noise is still there, but not as loud as before. I have a feeling it will get worse again.

Also, I found a newer SIB, which suggested to replace the "Window Guide Seal".

I also checked the Repire Order again, it says the "Roof Frame Seal" were replaced. Not sure if it's the same as the "Window Guide Seal".
