    Has anyone actually taken a db meter and tested where most road noise comes into the vehicle?

    I'm going to say doors and back wall obviously, but after you deaden those what's the next culprit?

    I may have a solution for the wind noise from the side view mirror area that is so bad... When I get off shift I will do a test drive on the way home to see if it works.

    I'd be interested in what you find! I'm about to start stripping apart my truck in the next week or two so I can deaden it and begin my install too. :D

    Are you talking about the sound from the passenger side? I think my antenna makes some crazy sound.

    No, if the antenna makes a sound its generally loose. There are 2 wind noise sources Ihave found. One is a bad isolation/seal of the mirror. The other is the sealof your weather stripping near where the hood meets the change in angle of the door near the mirror. I have solved the seal on the mirror but need to find a suitable work around on the air seal for the place where the weather stripping lets wind noise in. Thats 80% of the wind noise right there. My first attmept on the solution didnt work... will keep trying.

    Download a decibel meter on to your phone and test it out.

    W/o any hard data to back it up, I'd be willing to be the roof, then floor. I'd even put the roof before the doors. Almost all doors come with some form of a sound deadener from the factory. May not be the best, but better than the roof, which typically has none.

    I removed the mirror and put cld and ccf inside the area where the gasket on the mirror is located... where the wires go through. I had a poor seal there but other Tacomas I have listened to didn't have as big a problem as I had. Still not done the weather stripping mod... just too busy/lazy.
