So Ab, did it help with the trued tires? No vibrations?

I would say an improvement but not a fix, they are still there and just like before they come and go in intensity. Sometimes it's smooth, other times it shakes but not nearly as severe as before i started swapping things and not nearly as bad as some of the videos I have seen over the last couple years. Temperature seems to play a role as well as fuel level just like many others have stated.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

On the 2018 Silverado it listed a stronger and stiffer frame is in the works.

Customer conclusion the frame is too stiff and GM thinks it's not stiff enough?

 

Also, stated the sheet metal will be mostly aluminum and appears GM is going to get on the V-6 Teapot band wagon. However, there was no mention of changing the logo to Ford.

Good line

Guess they will have to pull their ads bashing Ford for using aluminum.

When I first read the article I thought it was parody. But, it was a serious article. I'm one of the lucky one's who doesn't have the problem with my truck and I've never rode in one with the shaking/vibration problem. So, it's difficult for me to size it. However, having read this thread regularly, I have come to the opinion that the root cause has to do with the more stiff and rigid frame being used from the 2013 models on. That, along with the steel sheet metal under certain conditions causes a resonance and/or harmonic vibration. I'm guessing this is why GM in 2018 is going with an even stiffer more rigid frame along with aluminum sheetmetal. Aluminum doesn't resonate or transmit vibration to the degree steel does. I'm thinking this is why we don't hear of this problem in the Fords. But, then again I could be full of crap

Interesting theory and as valid as anything anyone else has come up with.

 

And I'm at the complete other end of the spectrum, I really wish I could find someone with one that didn't vibrate. I'd love to take a ride in a good one just to know that they really do exist.

 

Where in the Dallas area are you ? I'll be in Westlake tomorrow, I think my flight lands around 11 AM local time.

I live in an unincorporated area that's wedged in between Lewisville on the west, Plano on the east and Carrollton on the south. Name of the community is Castle Hills. I just returned home yesterday from back surgery (stenosis, L1~L5, two rods and bucket of screws). Anyway, can't drive for awhile or I would seriously see if we could hook up for lunch. When on these blogs for awhile we all develop perceptions of some of the players. You strike me as one of a group that I would characterize as "the objective thinkers". Others, well.... There's a myriad of motivations and objectives, too many parse, that these could the categorized in. Back to the vibration though; I haven't been able to determine if the most frequent occurring complaint is vibration and noise caused by road conditions or is the source inherit to the truck? If it's external (road) then I come down on the side "hey, it is a truck". And, even if it cost $50k+ it's still a truck. Maybe, because I learned to drive in my grandfathers 1951 Chevy truck on wash board dirt roads around his east Texas farm I have different expectations, don't know. West Lake is a nice area, wife and I considered building there, and Argyle, several years ago. If you like good ole southern food, have your hosts take you to Babes, in Roanoke, for lunch. Great fried chicken joint. Enjoy your visit to Texas! God Bless Texas :)

I am currently battling the same vibrations found in every other 2014 Silverado, I have replaced shocks, changed pinion angles, replaced Ujoints, and drivelines professionally balanced, five different sets of tires since April, we have manually balanced the rims themselves, Bilstien 5100 shocks, re-torqued and re seated body mounts, and even weighted the exhaust in various locations with little to no help. I have made one observation that the 2016's seem to have a slightly different body mount bracket, don't know if that was something GM is doing to combat this or not but makes me wonder. Has anybody actually attempted to use a different body mount or just simply replace the ones that are there? I have thought a few times about removing one to dissect it to find out exactly what makes it work or not work in this case, I have theorized that perhaps the mounting bracket on the frame is not in alignment with the cab in some cases but haven't done anything to back it up yet. My case is a little different because I need to run E rated 10 ply tires due to puncture concerns, my truck seems to be pretty darn smooth for the most part when I put the factory five ply tires on it but they simply won't do for what I use the truck for. I can't believe that a GM engineer hasn't leaked some type of fix no matter how drastic to the public so we can simply go fix these things ourselves or at least make them better, I really like this truck and would be willing to do some pretty major modifications for a good solid fix if I knew of one

I have 2,200 miles on 2016 crew standard bed and I have No big vibrations but I feel a little in the gas pedal.Im thinking vibration is so light I can't feel it in the seats.when I give it gas the the pedal seems to vibrate very minimal.

Your vibration is probably coming from exhaust harmonics, mine does the same thing, i can hear the exhaust tone and feel the harmonics at the same time and only when giving a little more gas to speed up on the highway or when the engine starts to lug going up a hill.

Yes that sounds right,only when it under acceleration load,I never really got on it heavy didn't realize it maybe exhaust.Thanks

I'm rooting for you guys with this issue hope it get resolved,it bothers me to think GM hasn't figured this out.I personally wouldn't want to make another truck till I fixed the problem.I don't blame others buying another brand,but for me I rather be driving a Symbolic American vehicle before I go to my coffin and I willing to deal with whatever issues till that day comes.My next move maybe to buy a older truck do full restore the way I want it and drive a real American Vehicle.The price we pay now I think I would be better off although I like some technology that comes with newer vehicles.my 2 cents worth.

Haven't had any time to do any of my own diagnosis or get the on car balance, I put in 12 hours each day this weekend on a network move project for a client. Not fun.

 

On my way to work this morning though I noticed a 50mph vibration that I hadn't ever felt before. Not sure if it was a one time deal, if I had just never noticed it before, or if it's a new recurring issue. It was a much slower vibration than the one at 75mph. I'll keep monitoring it. Ugh.

 

I want to keep modding my truck, already have amp steps and a Corsa sport cat back, but I feel like there's no point if I can't get rid of this vibration. I rolled over some negative equity when I got the truck so I'm pretty much stuck in it anyway unless I want a different headache to deal with. If I can't fix the vibration I'll just have to deal with it and won't ever want to finish mods. :(

I have a similar 50-60 mph vibe in my truck, but it is sporadic. Some days it's there, some days the truck is butter smooth. All my high speed vibes don't exist now after getting these all terrains a while back. But that 50mph vibes feels almost as if it's lugging sort of, kind of lopey if that makes sense. Doesn't bother me enough to worry about it though. I also am continuing the mods on mine lol

      Cold start Miss, oil in cylinder

      By Keith179 · Posted

      I’m out of ideas on this truck. 2020 Silverado 1500. 5.3 135,000 miles. Has a p0308 and p050d codes. Smokes From exhaust when cold. Compression test passed. New plugs, wires and coil on cyl 8. Same issue. New coil on 8, no change. Replaced injectors, no change. Bore scope showed oil pooled on the piston after sitting overnight. Pulled head and had machine shop check it out. No cracks. Stem seals looked good, replaced anyways. He also ground valve seats. Put it all back together and still have the same issue. Bore scope shows oil on the piston again. Leaning towards maybe a cracked ring but unsure. Cylinder looked good when the head was off, no scoring or scratches. Any ideas on what else I should look for?  Appreciate the help

      2021 Silverado 2.7L – N232395310 – Can someone with GM dealer access check my VIN?

      By HeronLeal · Posted

      Just want to make sure it is covered by Special Coverage N232395310 Evaporative Emission Purge Pump 2021 Silverado 1500 Custom 2.7L L3B ~100k miles I'm getting DTCs P146B and P146F. VIN 3GCPWBEK2MGxxxxxx   I spoke to a person that works at GM and he said it is not covered after checking my VIN.   Is there anyone here who currently works for a GM/Chevrolet dealership and has access to GM Global Warranty Management / Investigate Vehicle History who could explain how the VIN eligibility is determined?   thank you

      Tire psi

      By jgaudet99 · Posted

      Thanks for all that information, I might purchase one and see if it will work for me, if not they may let me return it! Yes for sure the tires are definitely within limit for my truck empty, and when I do tow I'll definitely make sure to raise the rear psi for the amount of weight that's going to be on it.

      Tire psi

      By Chuck FB · Posted

      Yes exactly, more and more these days people/companies are afraid of liability issues so its easier just to say no rather than risk putting their neck on the line.    I will say with the Autel unit or when I used it last year on my truck, it wasn't like I could choose the 2025 model year or even the 2024 model year as that option was not there to manipulate the placard pressures but had to go back to 2023 or there abouts and then it showed up as an option, odd but that was how the software was then and I can't say one way or the other now as they throw out updates every so often. I still would talk to your tire dealer though to start with and they may do it for nothing but also they may have a comment on a better unit to purchase. All I know is that one of the large tire shops in my area happens to use these Autel units for their use and set them up to use the wifi and all of that jazz for constant updating because each tire tech has one handed to them by the shop but I just plugged it into my laptop to update it and yes if one is bought it has to be registered so you can get the link to do updates and then the unit has to be updated before its even used. I am not at all techy so it took me a bit but anyway just a heads up for anything you buy, most likely it will need to be connected to a computer to access the internet to have it updated to the latest software version before you can put it to use.   If your truck is near empty, those tire pressures you listed are a very safe upper range pressures to carry the weight, both the front and rear as I know they could be run lower yet with an empty truck. And if its a trailer and not some motorcycle your going to strap onto the front of your truck on a rack, you shouldn't have a need to inflate your front tires if your at 55 front already, its the rear ones that would need more air if you have much hitch weight.

      Tire psi

      By jgaudet99 · Posted

      Thank you, I'll check that Autel scanner out and see if it will work for me! Ya I can see GM's point of view if they lower the psi set value for someone and the person sell's the truck and the new owner puts the factory tires back on then their could be liability issues cause the psi warning light wasn't coming on when the tires were under inflated for towing their load and then it might be able to be traced back to GM lowering it.
