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

SOLVED FOR ME: I have a 2014 Silverado 5.3L LTZ and I have the stupid shake issue like so many of you. Oddly enough, I also have weird shifting like clonks which the US class action lawsuit only mentions 8 speeds when i have a 6. I road forced balanced the wheels\Tires and I have 3 sets of wheels so I know the vibration was not caused by one set. I tried tightening the leaf springs and it reduced the vibration but made the ride stiffer at lower speed. 

 

The solution for me was adding a AFM disabler from Range technology. The vibration is gone and the transmission shifting is now smooth. It's only been one day and I am so happy, that I wanted to share.

 

I do love the GMC Sierra AT4 with a 10sp but don't need the 6.2L so the rumors that 2020 Sierra\Silverado 5.3L will come with the 10sp is great.

 

If you put it in manual shift with it set at 5 to avoid AFM did the vibrations go away or did it take the Range device to stop it?

What a bunch of bullshit There is no way that the AFM disabler from Range technology stops the vibration issues in these trucks He must be a salesman

Last time I spoke with my service writer I told him about the vibration.. At the time I had oem 22" wheels with 285/55's.  He said that they were probably causing it.  So I put my stock wheels back on and took a video at around 75mph.

Thanks for all the good posts.  Until this forum post, I thought mine was the only one that did this.  I have a friend that has a 2016 GMC SLT, 1/2 ton 5.3 (I have a 2016 4.3) and she has the same vibration issue.  I am hopeful for a resolution, this is the only issue that frustrates me on this truck!

I am not a salesman. I am an idiot like everybody else that had a vibration and have been reading these forums and watched a bunch of videos. I tried a few things with no success and found a solution that works for my truck. I did try COR's thing about driving in M5 but the vibration wasn't as bad but the transmission shifting was not pleasant. 

 

Just like the other 832 pages of this thread, take the info you want but don't send out bad vibes you troll.

I tried M5 with my '16 5.3 and it vibed.  Vibes in neutral at 70ish too.  Apparently GM fixed it in the '19 models.  So what's the big secret GM??  They won't say because they're assholes.

After we have a large enough sample size of no confirmed issues on the T1 platform with plenty of miles on the road, it would be amazing if someone out there could thoroughly document the changes to the frame/driveline/etc between the 2 and try to conclude what may have been the issue on the K2's. Other than that, we may indeed never get a definitive answer on this topic.

My oversized aluminum driveshaft did fix my vibrations along with a set of yukon axles . However i do find that the center flip up consoles are very shake prone .

I would love to know if anyone with a flow through center console has ever complained of "THE SHAKE " .

The T1 is a completely different truck from the wheels up including suspension geometry, frame, etc. So the change you want to identify is the Entire Truck.

Indeed, what I was getting at is that there is a component or components that are different that are not causing this issue on the T1 (knock on wood). If it’s the relationship of all the components on the K2 causing it, then so be it. It’s just my inquiring mind that’s curious if it can be pinpointed.

2018 Silverado with the factory 20's and continental crosscontact tires. When I first hit 75 I swear drinks will come out of the center console much worse than the video above and at 80 it actually makes me nervous. It's the first time I have had it on the interstate and have a service appointment later this week. At only 1500 miles and a month of ownership I'm not liking what I have been reading here.

      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.

      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.

      Tire psi

      By Chuck FB · Posted

      I had a similar but different response when I talked to the service manager where I bought my truck in that he said GM corporate won't allow them to lower the placard pressure setting as they would get their hand slapped but that of course they have the ability to make that change. His suggestion was simply go to a tire dealer or third party shop that is willing to reset the pressures lower. However I chose to buy a tpms tool and partly based off of this very forum as it had been proven to work on the 2024 model ( Global B system ) and while I could have paid lots for a full two way diag tool, I didn't want to spend that much and bought the recommended Autel TS 508 and it will reprogram the 2025 model and assume it should do the 2026 as well. However the tool is rather proprietary to reprogramming Autel tpms sensors so that is a function I will never use, where as a real two way scanner would have many uses but also have yearly subscriptions etc where this 508 is free updates for as long as they put updates out for the unit. In any event it worked to lower the placard pressures and I often use it to adjust my actual tire pressures although will check with a mechanical gauge as well sometimes just to make sure that tires tpms sensor isn't lying to me.    My suggestion is either buy a tool that you know will work to adjust the system or start out by getting the tire shop you bought your tires from to reset your truck and if after that you still want a unit to do it yourself, get one at that point.

      Tire psi

      By jgaudet99 · Posted

      Here is an image of a quick Google search about these tires on my truck and it's exactly same psi recommendation the Toyo tires company gave me!    I'm not looking for anyone else recommended psi or anything, I'm just looking to see if anyone knew a way to get rid of the factory low psi warning light, because I'm not running high psi and ruining my tires when I'm not towing!
