You have zirk fittings on the 1500 other than the steering linkage? :surprise:
It says put 200-500 lbs in bed. Guess I could just tote my 5th wheel every where. Does any one have information on a fix for this problem? GMC has been aware for 8 years now and plans no fix for HD series, The Fords are looking better all the time. To bad I can't afford a new truck or I'd have one.
you are right about the Fords. I rode in a friends new ext. cab and it rode smooth as a car.
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?
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.

Good luck on this one now.
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.

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?
Your dealer is blowing smoke. Probably because he want you to buy it from him. Who did you talk to at the dealership?

The noise lasts until the exhaust system has a chance to warm up. After driving for about ten minutes or so the noise will quit. I notice that barometric pressure and humidity variations tend to change the attitude of the noise as well.
I had it checked out at one time and was told it is caused by a ceramic ball that is caught in the muffler. My questions are these:
For warranty purposes (catalytic is covered and muffler is not,) could this ball have come from the catalytic converter or are there ceramic balls within the make up of the muffler itself?
The muffler is the 3" dual inlet - dual outlet and have been told a new one is not available for it but if they could find it it would cost about $500 ?
Any help here appreciated!

It is my understanding that the catalytic is filled with ceramic balls/beads that are coated in platinum (???). That is why they are expensive. The exhaust emissions are reduced by a chemcial reaction that takes place on the surface of those little balls.
Mufflers do not have those balls inside them. Mufflers are just a way to reduce the sound, and are filled with various chambers and baffles to accomplish that. Maybe it is possible that one of the little balls escaped the cat and got into the muffler. The balls are not very big, it seems odd that such a tiny thing could cause a big noise. Call around to some muffler shops and see what they say.

Thanks, unbelievably enough the trombone noise goes away completely during times of dry weather and low humidity but immediately returns after a good rain or in times of high humidity. I think this may help attribute to the loud noise as condensation is in there with the pebble, plus it's probably rolling around in there as well, changing the attitude .........definitely a strange aberration indeed.
The fact that the muffler contains no ceramic balls is huge ammunition in getting this thing fixed within my 80,000mi exhaust emissions warranty.
BTW it was dealer that told me that it was a ceramic ball originally .
May be a battle but will keep the board apprised
thanks,
John
Thanks

Personally, I'd go to another dealer.
good luck on whichever you decide.
Seems to me that GMC would have a recall about this problem as the last 2001 truck I had did this as well except I did not get it fixed then. Back then I don't think they really knew a lot about this issue but they sure did this time. Just as soon as I said what it was doing they knew exactly what it was doing. I did not even get out of the parking lot with the mechanic before he said for me to head back to the doors.
Does anyone know if there was a recall and now it has expired or anything relating to this?
Thanks
