I'm pretty sure I've seen someone else have this issue. iirc the solution is something very simple like spraying WD 40 on it (or something to that effect). Can anyone help me out? I tried searching but couldn't find anything -___-
Are you sure its not the infamous subframe clunk? It sounds pretty similar to a CV noise, there are updated bolts to fix this but for most people it doesn't last so they resort to the Tyrol collar kit.
My subframe clunk was most noticeable while turning at slow speeds and when one of my heavier friends got into my car. What you could do is order new bolts from ECS for like $14, install and torque and see if the noise goes away. If it does then you know thats the problem. You'll want the tyrol kit if it returns though.
