Yeah, mine was so bad I could feel it in the floor boards and the steering wheel, and my passengers could feel it in their feet as well. Now it seems more like you are describing yours, "nosier" but tolerable.

 

Well i kinda noticed a little shimmy in the steering wheel when in auto for speeds up to 45-50. But by then im usually shifted out of auto back into 2hi and it goes away. It's almost like a wheel being out of balance up front.

The Dealership installed everything on my truck and I have a signed document stating that they will still stand behind factory warranty.

They are pretty awesome! I took it in because I was having some vibration issues at 70 mph(more than there should be). They replaced all 4 tires(35x12.50x20) and fixed the problem. They also gave m

I had a 2010 Silverado Z-71 4X4, I drove it for 70,000 miles and the only time it wasn't in in 4-Auto was when it was on 4 HI. I always left it in 4 auto and you'd never know it until it was needed. With my 2014, I get a very low moan sound when in 4 Auto if I give it even moderate gas. I leave it in 2 wheel and use 4 HI when it's snowy or when I'm off road which isn't often. The 2014 doesn't work anywhere near what my 2010 did as far as 4 wheel auto. I did take it in and dicuss it with the dealer, and they said it was normal and to only use it when it's really bad out. Personally I think they took a step backwards with this but what are you gonna do.

I agree 100%. I had an '07, '10, and a '12 that would be in 4-Auto from October through May and you would never know it. They took a big step back with the '14 and the supposed "square chain".

How about this:

A 2016 Silverado 1500, installed a 5.5" Rough Country lift, easy enough, changed the 342 rear gears to 410's, went perfect.  Changed the front diff to 410's also and noticed a loud groan in 4auto. Took front diff out again and rechecked everything, backlash, pinion depth and preload, all within specs. The truck was quiet before lift kit, after lifted and before gear change it already had a louder 4 wheel auto.  The kit drops the front diff as not to put a bind on the front driveshaft. 

So bottom line, after pulling front diff twice and checking all specs, it still makes noise in 4auto.  Little louder in 4hi but doesn't seem as bad as auto. 

Anyone have this problem?

Are you ever going to provide any actual informational help in these threads or just continue to make these generic useless posts telling the poster to contact a random email? Your posts do not contribute any useful information to any of these threads. My guess is almost no one ever contacts your email as it probably wouldn't do any good anyway. I'm guessing that's why you disappeared and stopped posting for so long.

I've noticed these type of accounts on other automotive forums too. I'm not sure if its a bot or a person, but I think the only thing these types of accounts do are get you in contact with a dealer to get stuff fixed.

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need.webcrimsNY

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
