Meh, only difference in the consoles is rigidity. Nothing more than that. The less rigid the feature the more likely to develop some type of movement.

If it were that easy i would have a "flow through" console.

What i really mean by all of this is that i think a lot of people say they have a vibration issue because they can see the console move on the highway .. If you had the same truck but with a flow through centre console 

would you even notice the vibrations ? i know before i had my truck fixed the floor and seats didn't really vibrate more than a normal truck but the lid for the fold down seat always shook like crazy .

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

Sounds a bit redundant but thought I just as well add my 2 cents. Have had my 2017 Chev. 1500 Silverado LTZ 4x4 with 5.3 since last year when I bought it new as a carry over with about 50 miles on it. It is a pretty truck and I couldn't figure out why it was still on the lot. I am beginning to understand why after reading many of the remarks on this thread. 

When I first drove the truck, I told the salesman I felt a little vibration and thought the tires needed balanced. He told me he would have them balanced for me before purchase and did. The vibration I am getting is especially noticeable at first start after it has cooled off. It seems to improve at the lower rpm's after a few minutes of driving. I still notice some vibration at highway speeds that still feels like a broken belt in a tire or something but am now wondering if that really is what it is. I only have 5000 miles on the truck and finally asked the dealer about the issue at the first oil and tire rotation. He told me there was no service bulletins on the issue! (after reading this thread--I am not sure what he had been smokin before telling me that)! Anyway, I took it to another dealer who immediately told me there are known issues with the TC and he has scheduled an appt. for this next Weds. I will take it in on Tuesday night so it can sit and be nice and cool for the test drive in the A.M. He assured me that the mechanics are aware of the issue and they wouldn't need to put any diagnostic equipment on the truck but rather would be able to tell by driving the vehicle. Stay Tuned! Thanks for listening and any other thoughts are appreciated.

Well, just got a call from dealer telling me that they first thought it might be the transmission but they checked and the transmission had already had the latest programming had already been done on it so they looked further and put some new programming in the ignition control model but that he really wasn't thinking that helped but to "help put my mind at ease" the technician told him he checked everything out and that it might just be "the nature of the beast"!! Seriously???? Never even offered to change out the fluid in the TC or offer anything else!

Now I am told by dealer that the TC problem didn't apply to my 6 speed transmission-----tells me it is just the nature of the beast and happens because GM is trying to squeeze out all the mpg they can. My next step will be contacting GM directly!

Bought a 2016 Denali 6.2L 4x4 last week with 53k miles on it.  Shame on me, I didn't do an interstate ride as part of my test.  Took a road trip to go camping over the weekend and when I got to 73 mph it was pretty bad.  It got worse as I increased speed to 80 ish.  I immediately started thinking bad tires/balance, but a quick search revealed that it's actually a thing. ?

 

That led me here.

 

So...I'm guessing I have about 6k miles of powertrain warranty, and should hit up the local GMC dealer about it before I get to 60k.  I'm assuming a RFB or regular balancing of the tires won't actually do any good at this point and should actually look at the service bulletin for the fluid flush or check into getting another driveshaft to start.  If I can't fix this I'll have to dump the truck. We do too many road trips as a family to deal with this.  Which is a shame.  It's such a nice looking pickup.

Update for me: 

 

Balancing the tires removed 90% of the vibration at speed.  Tech at Goodyear told me that all 4 were over 3 oz. out of balance.  He got them and and rotated them and I'm riding again.

 

I'm hesitant to say it's fixed but it's definitely much better.

This is how mine was when i was fighting to figure out what was causing the vibration . Balanced the wheels got a little better changed the axles got even better then was 100% gone with new driveshaft .

Checking back in after a weekend of driving and I'm definitely harsh vibration free under 85 MPH.

 

For what it's worth, the carfax I have for the truck states that the torque converter was replaced in 2017 on this truck with 25k miles on it at the time.  So I think I'm good on that front.  I just want to get the driveshaft balanced and checked out to get any further contributors to the slight issue remaining resolved.

From all the reading i have done i have not seen anyone re-balance there driveshaft and have it fix the vibration the issue is the driveshaft is made of paper thin aluminium and its full of cardboard . Because the driveshaft is so thin it resonates vibrations badly.

Hey Kyle - thanks for the advice.

 

I did hear from someone locally that took out their driveshaft and had a driveline shop do some analysis on it.  There was excessive runout in the middle of the shaft.  The shop put it on a lathe and made it run true.  Rebalanced it, and the guys vibrations were gone after that.  I was thinking about doing the same thing as far as having the machinist check it out.

 

Replacing with a high quality shaft is probably a good idea too, along with the upgraded axles.

The factory driveshaft is 1/8" thick i don't think you could machine it at all . The unit i had made is 6" diameter and 1/4" thick .

I've been following this thread for a long time, and thought I would share my experiences as well.

 

2017 Chevy Silverado Crew Cab - 35k miles

22" Wheels with Bridgestone Dueler AT's

 

I purchased this vehicle with 8k miles in 2017. I didn't notice the shaking/shimmy on my test drive. With my truck, it was only noticeable on smooth, long stretches. A lot of the highways around the dealership are pretty bumpy, and driving on them doesn't let the shimmy really set in. I could feel it at 40mph, on really SMOOTH roads. It was also bad around 70-80ish.

 

After about a week of driving it, i really started to notice the shake. I took it in 3 separate times and was told that the tech didn't notice anything unusual, and nothing wrong with it. I finally got really fed up with it and demanded a tech ride with me. I got one, and I took him to a section of roadway where I knew it would shake - he agreed something was wrong... Back to the garage.

 

I'll skip the rest and just tell you what they all did, over a period of time.

 

3 of the 4 tires were in the mid 30's for roadforce - I got 4 new ones (same Bridgestone Dueler AT's) - Still shook after that.

They found lateral runout on the rear axle - replaced left and right inner axle shafts - Still shook after that.

They found play in steering gear bushing - replaced steering rack - Still shook after that.

They replaced all shocks/struts - Still shook after that.

They replaced drive shaft - Still shook after that.

 

I drove it until my next oil change and when I brought it in, I asked if they had roadforce balanced the new tires when they mounted them, they did not. SO, I said do it on these new ones. 2 of the 4 new ones were in the low 30's again. Other two were 13 and 10.

 

Two more new tires, rf balanced at 9 and 11 - and its ALMOST completely gone. At this point I am going to just accept it as its almost non-existent and I'm so sick of dealing with it.

I have been dealing with the vibration issue for several months now.I have a 2018 Silverado 5.3- 6 speed trans 2 wheel drive and I have 22,000 miles Mine is mostly felt in the steering wheel from 50 to 70 mph. The dealer started by changing the torque converter with no success. The next visit they changed my motor mounts and had no luck. The next visit they did the trans fluid flush and the road force balancing of the wheels and this last time in the shop they took the wheels off a brand new truck on the lot and did a lot of pico scope tests and they had my truck for two weeks They also road force balanced my wheels again. The service manager told me when I picked it up that all the pico scope readings were within spec and that there hands were tied from any further repairs This morning I got the number for GM and called them and they are connecting me with a senior service advisor to get my issue fixed By the way my truck vibrates exactly the same as when I first took it to the dealer

      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.
