I have a 2016 Silverado 1500 I've been trying to locate a squeak noise. Dealership told me it's my leaf springs but it only happens when I give it throttle. Anyone have any sort of advice. When listening to pin point it comes from all sides!! It's getting on my nerves badly!

Have you had a friend with you to try and pin point the sound location? I had someone help me yesterday pin point a different issue and it was very helpful. Have them either inside or outside the truck. In my instance they were under the truck with the E brake on as I lightly pressed the gas and they were able to pin point the issue.

My father was in the truck with me radio down windows open and we both heard it on our own sides of the vehicle. Possibly coming from the center?

Put your trip meter screen up; at the bottom right you'll see it says V4 or V8.

As you apply throttle; if you hear the squeek happen and see the icon switch from V4 to V8 then that means it's the exhaust flapper. If so you can clamp the flapper open to confirm the noise has stopped.

I'll try that in the morning!! Thanks for the opinions and advice

Well, do you have the infamous V4 to V8 exuast flapper squeek or is it something else?

From the looks of things yes I do I changed my screen to see if it followed v4 to v8 and lo and behold it does lmao

Well, that's luckily that's easy to fix. In my opinion just clamp it open; if you go to the dealer they may replace your catback but that doesn't mean that will fix it; at least in my case when they replaced my catback on my 2015 the squeek went away but a louder more annoying rattling replaced the squeek. That's why I recommend just clamping it open; just my opinion.

They told me it was dirt getting inside my leaf springs. But ehhh next time I'll go for my annual oil change I'm going to tell them it's not my suspension. Possibly in due time I'll change out the exhaust for something where I can tell the truck is running at a red light.

These trucks have problems with the leaf spring bushings squeaking too. But based on what you found I would say your noise is definitely the Passive Exhaust Valve. Just show the dealership the TechLink that was linked above.

 

It doesn't hurt anything but is really annoying. I have been living with mine for a few months now. My dealer knows about it and will replace it whenever I give the word be he isn't sure the new valve won't start to squeak too.

Thanks for the exhaust flap "squeak" heads up. My truck just hit 80,000 kms, and almost like someone threw a switch......there's that noise. I would guess there is no code or CEL related to this? And, is this just a noise and no mechanical issue for the future? Like a few other small annoyances, I prefer to "let 'er buck"!

Was the rear springs well and spray silicone lubricant into them and see if it goes away. This is only a temporary fix but it will tell you if it is the springs.

Just had my exhaust replaced for this problem. Or you can buy the range afm disabler for $189 and you truck will stay in v8 so no squeak. If you clamp the valve open you will have a helicopter noise in v4 the flapper prevents otherwise.

Another free way to disable AFM is to shift down into manual and lock out 8th gear aka set it to 'M7' (6th gear on 6-speed transmissions, 'M5').

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
