    Well, that was definitely the problem. I took the deflector off and the noise is gone. I'll live without the deflector, no biggie.

    ('04 Silverado 1500 reg cab long bed) ... bug deflector arrived & installed... sure enough, the flaps that cover the hood hinges RATTLE noisily around 55 MPH (have not gone above that, and not a problem at lower speeds). I'll be keeping the deflector on, for my upcoming road trip to FL. This particular deflector is held in place by five screws (no tape involved), so it's easily removed & reinstalled (whenever I need to do so).

    I have a 2010 Silverado and I just bought a WeatherTech bug shield for it. After I installed it I heard the same flapping/tapping noise coming from the front. At first I thought it was the edges of the bug shield itself hitting the hood, since the outside 3-4" are not supported by anything underneath. But after searching the internet for causes, and finding I wasn't alone and mostly everyone else says its the side of the windshield flapping, I am going to use some tape and test it to see if thats really the issue. If it is, I will just get some automotive silicone and squeeze some under the weatherstripping and hopefully that works.

    I know you can get clear silicone bumper pads that are double-sided-tape.....simply put them between the
    Bug Deflector and your truck hood...eliminates movement, which in turn is probably where some of the noise
    is reverberating from right towards your, old Bug deflectors from about 15 years ago were mostly
    flat.....had less noise, but boy did they flap in the wind like a lost kite !!!!

    Default Bug shield causing tapping noise on windshield

    Hello blue1992,
    I also have a 2010 Silverado with a bug shield tht is causing annoying tapping noise on the right side of the windshield starting at about 65 to 70 mph. Did you find a solution and would you mind sharing? Much appreciated.

    Our 2011 had the GM deflector installed by the dealer and it caused a flapping/tapping noise from the top of the windshield. I asked the service department about the noise and they were well aware what caused it and how to fix it at no cost. They remove the top trim from the windshield and add extra insulation to the top, then re-install the top trim. Worked perfectly, the noise is gone.

    I just read thru the whole thread and i've heard three different suggestions as to what the problem is.

    It sounds to me like the main problem is that the bug deflector is changing the shape of the front end of the truck, which is altering the aerodynamics of the vehicle, causing the wind to hit areas harder in spots than in others.

    Different companies offer different styles of bug deflectors and different model years have different designs, 99-02 had one front end, 03-05 had another, in 06 they changed the hood, and in 07 entirely new body style. All with different aerodynamics, especially when an aftermarket bug deflecter is added.

    It really depends on what style bug deflector is being used and the body style of the truck its being applied to.

    Like several have mentioned, certain combinations of body style and bug deflectors work well together with no noise at all, so when ordering this provides a good starting point. However, if you're unlucky to have already purchased one are being tormented by a sound gremlin like many others have, then like already mentioned just do a little detective work and find where the noise is coming from and by the sounds of it the problem can be solved with just a bit of double sided 3M padded tape.

    If You're dead set of installing a Bug Deflector because it will "complete the look you're going for" I wouldn't let this small issue turn you away, especially since it sounds to be a straight forward, 30 minute, drive way fix.

    Hope this helps.
