I was reading a previuos post that mentioned windshield weatherstrip rattle. I have a 2004 tahoe and i hear a rattle coming from the roof at about 60 mph- how do you physically check to see if actually this is the noise?

Do you have a bug deflector on your hood?

no bug shield- the noise is coming from the drivers side front roof area

The reason I asked is that a lot of people have the issue of turbulence from a bug shield.

 

If you think it is a molding making noise try taping it down with masking tape and going on a test run. Pull portions of the tape off until you isolate the area that is rattling. You can use urethane to seal it back down if it turns out to be the molding.

 

If not I guess I just wasted your time. :rolleyes:

 

Roof rack maybe?

Take duct tape and cover the top & sides from the glass to the paint. One strip will do it. Thake vehicle for a ride and check it out.

Here is some information that might be of help, I never heard of this until today (GM has alot of bulletins on our trucks):

 

 

 

 

Subject:Tiny Rattle Noise From Roof At Highway Speeds - keywords body bow canning headliner metal sheet speed tin wind #PIT3067C - (11/08/2006)

 

 

 

 

 

 

Models:2003-2007 Chevrolet Silverado Classic

 

 

2003-2007 GMC Sierra Classic

 

 

 

 

 

 

Document ID# 1871435

2004 Chevrolet Chevy K Silverado - 4WD This PI is being updated to add 2007 models. Please discard PIT3067B.

 

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

 

<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1871435&psdid=437&evc=sm#ss1-1871435">

Condition/Concern:

Owners may comment on a tinny rattle type noise from the roof at highway speeds. This noise normally occurs if the vehicle is equipped with a "Topper/Cap/Camper Shell" that is higher than the roof line of the truck or when towing a trailer.

 

<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1871435&psdid=437&evc=sm#ss2-1871435">

Recommendation/Instructions:

To correct this concern, use an expandable (minimal expansion, such as, 3M 04320, Kent P10630 or equivalent) foam between the roof cross bow and roof sheet metal. Then install four 10" x 10" sound dampener pads to the under side of the roof sheet metal.

 

One supplier of sound dampener pads is Kent Automotive at 1-888-YES-KENT. Kent part number for 10" x 10" pads is P32947 or equivalent, quantity 10.

 

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

 

 

 

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

My 05 did and my 07 NBS does it. The fix is ( for me each time) to put electrical tape down the two sides of the windshield where it meets the seal, and keep it there. The tape is black, just like the seal and the ends of the windshield.... so you can't even see it. I leave it there and have had no problems.

Any auto parts store usually carries it for about $3.

 

Go pull up the weatherstripping on the edges of your windshield, and you should be able to see what size/thickness of tape will fit under there.

      GM Hard Folding Tonneau by REV review

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
