I have a vibration that sounds like roof area behind the driver with hard acceleration (mostly third gear).
I suspect it it from the sun shade louver. I can tap around on the louver and I got a vibration tapping at the top center. Well that I found is one of my center louver supports (in the middle is cracked). So I'm going to repair that. But I also noticed the "rubber" molding where the sides rest on is very hard. Is that suppose to be a soft rubber?
