About a month ago, I searched the forum and found a posting on how someone fixed their Wheel cap noise. I have the VDP rims with the cap, about 6 inches in diameter, and every time I hit a crack in the road at low speeds, the darn things rattle. They look really good, but this noise is driving me nuts, and I'm considering replacing them. Has anyone else had this issue and been able to resolve it?

 

Spray foam like they use for home window gaps ?
