Is this prob;em only in my car, or your rear "vanity" shelf rattles and squeeks like a motherfucker?! I'm talking about the shelf that hides away the stuff you'd keep in your trunk.. I've tried everything i could think of to stop this thing from rattling, but still on uneven, rough roads all I can hear is "Squeek-squeek!! Bam-Bam!!" Anyone solved this problem yet?
