On my 02 Tundra when I installed Frost King 1/2 Caulk backing rod the dash rattle stopped. 2 weeks later the rattles came back and the foam is rectular shaped compressed. When u guys install it do you guys try to shove it so it is under the dash where you cannot see it. I installed it so it is visible between dash and windshield. Should I try one size bigger which I think is 5/8 of an inch???

I did this a few times and after a week or so, the rattles would come back. This happened no matter how deep I placed the backing rod. I finally gave up and folded a black sock neatly and wedged it in there. My trusty sock has been going strong for about a year now with no rattles! The sock was of course washed before I put it in there.

The backing rod will always probably take shape. Maybe use your defrost on warm to help make it seat better?

Otherwise...

TURN IT UP!

i've had the same problem as you, about a week later, the sounds are now back with the backing rod fully compressed. seems like the next idea is just to put a sock in there or towel or some sort of thing like that.
