HEY I'M NEW TO THIS, JUST TRYIN' TO GET SOME FEED BACK. IF ANYONE OUT THERE HAS HAD THIS PROBLEM. I'VE GOT A 2004 CHEVY SILVERADO 1500 CREW CAB Z71, SOUNDS LIKE A GRUNT WHEN REAR END UNLOADS AFTER BRAKING OR WHEN TAKING OFF FROM A DEAD STOP. SEEMS TO ME IT'S COMING FROM THE LEAF SPRINGS BUT I'M NOT SURE. ANY INFO WOULD HELP, THANKS

I have a 2007 Sierra 1500 Crew VortecMax with a bug shield. I am experiencing a popping noise in the bottom right corner of the windshield. I only hear it when it is really windy or when I am going +65 mph. Someone had told me that GM didn't wind tunnel test their trucks with bug shields on them, that is why I am hearing the noise. Has anyone ever heard of this???? THANK YOU.

Replying to: stobes01 (Oct 03, 2007 10:16 am) This "feature" was addressed a couple years (or more) ago on trucks with bug shields. Seems that they applied tape or glue to the edge of the windshield to stop the turbulence induced noise. Anyone else?

I don't have a subscription so I can't post the TSB but the TSB number is as follows: GM TSB#04-08-48-003 Windsheild Reseal You can find more info on it at www.alldatadiy.com if you want to pay for a subscription. Being that you're out of warranty by far it may or may not be worth your while. What is says is for the dealer to reseal both sides of the windshield with a GM approved adhesive. At this point I'd buy windshield adhesive at checkers for $5 and go from there. Lift up the rubber flap, add the adhesive and tape it down till the adhesive cures. Good luck. |

Replying to: akjbmw (Oct 14, 2007 7:32 pm) I have read elsewhere that the wind turbulence lifts the trim that holds the windshield in place. If you secure the trim with adhesive, it goes away. A friend with a F-350 had the same thing happen at any speed over 45 mph. We finally found that the rubber molding around the windshield was loose along the top of the windshield. The wind created a vacuum as it travels over the roof, lifting the rubber strip and making it vibrate. When stopped, you couldn't see anything was wrong. He glued it down, the noise completely disappeared. Hope this helps. 1offroader |

It's a buzzing sound. I thought it was the fuel pump and replaced it yesterday but while driving it that night the same noise is still there. I realize that it could be the new fuel pump making the same sounds but with my luck that's probably not it. What else is back there that could be making the noise. It does it while moving or standing still so it's not the rear end. It doesn't do it all the time either. Thoughts? |
