That's not what my noise is. I had the vent hose replaced and it still does it. I believe it's the Z71 badge on the front left fender.

Another reason they should have never put these on the front fenders, and should have left them on the rear! :D

Try putting your truck in auto 4wd mode when you hear the sound and notice if it disappears.

The noise in my truck goes way when I put it into auto 4wd. What would this indicate as the problem?

I have a 2019 RST with the 5.3 two wheel drive. I believe the sound I hear is some kind of radio ground noise. It goes away with volume all the way down on radio. I wonder if there is a fix.

It is a problem with the front axle on the driver side. Check out the "jingle jingle only in 2 wheel drive" thread. There is currently no fix for the problem.

I will have to discuss this with my dealer, I too have this strange high pitched harmonic type noise.  I haven't been able to pin point where it was coming from since I am hard of hearing, my kids hear it.   If I left off the accelerator it stops immediately.   Not too hard to duplicate the sound.

My Truck was repurchased for this issue it’s a problem with the front differential and the drive shaft on the drivers side. Find the jingle jingle in 2WD thread in the trouble shooting section it’s over 60 pages.

Did you ever find out what the issue was here? This sounds like a very similar issue that I have in my 2020 Silverado. Just picked it up last week and I already hear a metallic/harmonic sound when accelerating.

Sorry for resurrecting an old post. I thought I would ask here before starting a new thread. Going back in for the 4th time for this issue and was wondering if this repair has held up long term. I was thinking it was 8spd trans related. For my truck the noise is only noticeable at certain transmission temp. Yes it sounds like Rudolph's nose. The dealer has reflashed the TCM, performed a cleaning of the trans mount, and performed bulletin #19-NA-121 pertaining to trans fluid.

The noise persists. It is marginally better. Better mostly around the city but still pretty brutal on the highway.

So, wondering how #19-NA-005 fuel tank filler pipe has been the long term cure.

thanks

Sal

Mine did the same thing when accelerating and the whistle would go away when I let off the gas. It was the flapper valve in the exhaust. I wired it open and the noise went away and hasn't came back.

I realize this is an old thread. But I was having a similar issue with my 2019 Silverado.  Took it in and was told it was the “idler” they replaced it and no more high pitched whine.  Hope this helps anyone with the same issue

I have the same noise on my 19 RST Crew.  I have had two dealerships drive it.  One said it might be a bearing ( to me it doesn’t seem like a mechanical noise, the other said needed new tires and alignment.  I have had it aligned at 22,****** miles already.  Both said no bulletins where put out on it.  Very frustrating.

I’ll bite. I have more of a whirring/whining noise at 60-65mph. Getting annoying. Does not sound like a whistle or high pitched at all. My brother say it sounds like the front differential but I’m in 2wd. Or heavy mud terrain tire sound. Anyone else?

    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that. 
    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
