High Speed Wind Noise On 02 Ext Cab

[Babyhauler]

Hi truck people,

I get a lot of wind noise from the front passenger door on my 02 1500 ext cab 2wd, 143000 miles. Some of it also seems to coming from where the ext cab and front door meet. I have plenty of miles in other 1500 trucks in this body style and year. They were not this loud. This gets really loud, especially above 75. Sometimes it starts around 65-70. It may be a few miles before it starts on some occasions. If I draft a large vehicle or 18 wheeler, it will quite down. That beats up my paint and windshield too bad and makes the truckers mad.

I have tightened the latch points on the ext cab door and on the front door. They seem to fit nice and even at the A-post and everywhere else around the doors. The doors fit tight and must be shut firmly to latch correctly. You can easliy tell when they are not. Left and right door gaskets are not crimped and appear correct. Silicone lube helps with squeaking, but not the wind noise.

What's next? Lower the windows and adjust the upper door frame inward(bend the hell out of it)?

Put a bug deflector on it to push the wind up.

New door gaskets? TSB?

Anyone else had this and fixed it or know of a cure? Other than slowing down.

Thank you for your help.

I'd like to hear what others have done for a cure to this too.

On my 99 NBS my hinges were shot.

I replaced them and the door closed like butter and wind noise disappeared.

Unfortunately, I wasn't aware that the door check was busted too.

Eventually, the door over opening screwed the hinge again.

Sag & wind noise have returned.

I picked up a new door check.

Got to get a new hinge kit and do it all over again.

Hopefully for the last time.

On my '01 Sierra C3 the hinge appears to be fine but yet I have wind noise also (Just bought this truck last week).

I believe in this case I will have to massage the top of the door a tad and persuade it to keep quite.

Looking forward to seeing how others have handled this.

Andy, I think I had the same problem as you with my 05' Silverado extended cab. Like you, I tightened the door latches and all but the wind noise was still there. Then I replaced the window latch with a shorter (I think) one. This sucked the pass rear window in tighter and the noise disappeared. This was/is a common problem. I got new window latches off ebay. Let me try to find you some links.

 

*edit, found an ebay link for latches. But first, you can do a small test to confirm that the noise is coming from the rear window. With a passenger sitting next to that window, get the truck up to speed until it starts whistling good. Then have the passenger slowly apply force outward on the window near the latch. If the whistling sound intensifies with force like it did on mine, the new latch is likely your solution.

Thanks for the info.

There seems to be some noise from the back door/window area. I think mine is primarily coming from the A-pillar area. It is not a whistle, just loud. I will definitely test the back windows as the sound can fool you sometimes. Any other ideas if this one does not work?

 

Thank you,

I just went out and checked the back window. The top and bottom corners flex out fairly easy. The gaskets seem to be laying flat without a lot of give to them. Has 8 years of being mashed made them less effective?

Also, the black trim piece that runs up both sides of the windshield will easily flex out 1/8-1/4 inch on the passanger side. Enough to make alot of noise I would guess. I do not know how those attach properly. I cannot imagine a trim piece on a windshield should be that loose. Duct tape test time. Any windshield installers out there?

 

Thanks

My problem turned out to be the 3 - 7mm bolts holding the window frame in were loose. Try that first, then the latches.
