2016 whine noise

Bought a 2016 1500 Sierra CC with 6.2 8 speed and max trailing with 3.42. The next day after driving it home I noticed a whine noise between 40 and 60 mph. The noise speeds up and slows down with speed. Below 40 I can't really hear it and once over 60 there's too much road noise to tell. I've read a few things on here about transmission whine and rearend whine. I don't think it's the transmission but I'm having a tough time pinpointing exactly where the noise is coming from. It kind of sounds like it's in the right front but I can't be positive. Just wondering if anyone else is having something similar or has any suggestions on what to check. My first thought is I'd like to put it on a lift and run it to try and locate the source.

If the truck is brand new, give it a week. If it keeps up, take it to the dealer

I've had it for 2 weeks now. It's got about 500 miles on it. Was hoping I got rid of the problems with my 2015 but looks like I've got new ones now with this truck.

My 16 sounds like it's doing the same you described.

Almost like engine noise right ? Maybe from rear or maybe trans ? At first oil change I'll have to give the Forman a ride just to be sure it's not normal. Lol

This is not sort of thing that gets better with more miles. It gets worse because it is the result of improper differential gear adjustment or poor quality differential gears, or both.

I thought maybe it was coming from the engine because it sounded like it's coming from the front but if I take it out of gear and basically let it idle while coasting it still makes the noise so I don't believe it's the engine. To me it kind of sounds like a bearing that's just starting to go bad but the sound doesn't change when you turn the wheel back and forth. My uncle bought the same exact truck the following week and his doesn't have the noise so something is not quite right. There was I believe a bulletin about transmission whine at one point but you'd think that fix would be rolled into production by now. I'm gonna have to make an appointment to see if they can figure out what's going on hopefully. I can almost guarantee they'll say they can't duplicate the noise based on my past experience with my 2015 and saying everything was operating as designed with the transmission even though the thing studdered into the next gears and going up inclines like you wouldn't believe. Seriously they couldn't feel the whole truck shaking. For an almost $60k truck this thing should be flawless. I know nothing is perfect but this day and age things should be better than they are.

Exactly that's why I wanted to ask others to see if I'm not the only one. Just gotta get it in and have it looked at asap.

I'm dealing with the same noise issue on my 2016 GMC 1500 Sierra. It has 2,700 miles on it. Been to the dealer last week They had the truck for four days and all GM would do is to tell me to drive the truck and put more miles on it. Was

instructed to bring it back for a "inspection" if it get worse. The service manager and writer both heard the noise too. Well to say the least I am a very unhappy GM customer right now! I don't even know what to do next. If I take it back

their going to just tell me the same thing.

It's not tires?

 

I'm trying to understand what it sounds like. Can you post a video?

It definitely sounds similar to a tire noise. Like the noise you'd have if you had a more aggressive tread pattern. These tires are the Goodyear Eagles. I had the same tires on my 2013 and never got this sound. Also the little I've ridden in my uncles identical 2016 I haven't heard the same sound in his. You make a good point though that gets me thinking about the tires. Easy enough to prove if we don't hear any noise while it's running on the lift. Have they had trouble with this particular tire before?

The first time I heard what was described as a whine in my vehicle, it was determined to be improper differential gear adjustment and poor quality differential gears. It got worse with time. Ended-up changing the rear differential and it happened again. Traded the vehicle before warranty expiration. Wish for tire noise

Tire noise and differential whine are completely different noises. Noisy tires tend to make steady humming noise which increases in level with speed. Differential whine is higher pitch whining noise that seems to be most pronounced in 40 to 50MPH range. Often it occurs only while the differential is under load, i.e. your foot on the gas pedal, sometimes only while coasting (foot off the gas pedal). The latter case is of course less annoying because most of the time the differential is under load.

I have a whine that speeds up ad slows down with speed. Very faint.

 

Dealer said it's the tires. The good year SRAS are crap.

 

I notice that it's worse the colder the tires are. If I'm doing a ton of highway driving to the point the tires are warm it disapates.

 

Never heard when I bought the truck, but it was 60-70 degreees.

 

I started to hear of it when Temps dropped into the 20s.

      Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

      By Policeoff01 · Posted

      Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
