I used expanding foam to seal up my IB wall, and also fill a couple relatively small voids to seal my trunk from my cabin as best as possible. I now have a lot of squeaking coming from that general area of my car, although it's not always there. I'm pretty sure this is what is causing it, it just sounds like that's what it is. I noticed it very infrequently after I first installed everything this summer, but it has seemed to have gotten worse since then. I have no idea if it's because of the cold or if it's just a factor of time.
So, has anyone else had this experience? Any thoughts as to what can cure this, or what to use next time to prevent this?
