That is the dreaded window vibration problem..it is fairly common on Tacomas and has a Toyota Service Bulletin to fix it. It is a design flaw in the window seal that vibrates and causes and loud noise inside the cab. I thought the door seals were failing, but it turned out to be the window seal. Mine had it, but the dealer could not replicate it and did not enter it into the computer. I found the TSB myself and went back. My truck was 1k over warranty and they blew me off. They would not fix it. I complained, but it made no difference. I would do the following:
Get to your dealer before your warranty expires.
Make sure he logs it into the computer.
Tell him there is a TSB for the problem.
Here is the number: NV006-07 AUG 07 Body - Windshield Wind Noise at Highway Speeds

You should be good to go after that. It is a very simple fix. They just run a bead of silicon in between the gasket and the truck.
Good luck and I hope this helped.
