Another new set of tires installed today and they say the PicoScope shows it to be vibration free. We shall see, i'm going to pick it up shortly.

good luck

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

I didn't read this whole topic but mainly read that people are having vibration issues with gas pedal and steering wheel. Not my issue but, has anybody had issues while turning and TCS light comes on and gas pedal shudders?

I would imagine its most likely associated with your lift. Maybe ask on this thread.

It seems like increasing the size of the tires can cause this too, when turning the computer thinks your tires are turning at an abnormal speed, making traction control/stabilitrak turn on. Programming for larger tires might help.

I would request PICO reports from before AND after so you can compare. Validate their data, otherwise its just hearsay.

I agree with your thoughts. I have replaced all shocks on my truck and it has helped some but not cured. I have looked at those Sulastic shackles and they really do look like they could work but I am just about done spending money on this thing. I keep looking at new rigs as well....I sure do love the way my truck looks just not in love with driving it on the highway.

Well I pulled the trigger on the sulastic shackles. They have a lot of good reviews so we shall see. Should have them next week and install them next weekend. I'll let you know how the install goes and if they improve the ride quality.

New Chevy owner (2015 Chevy LT Crew, 5.3L V8) - just picked up truck from dealer yesterday. Test ride went ok, didn't notice any vibration. Felt a bit of a vibration at 35-40mph, thought maybe its the wheel balance.. then I find this thread. Oh boy.. I thought I was moving away from Ford to a more reliable design that's been proven. Did not expect this.

 

I've read a bit of the thread (but not all 356 pages!!)

 

Is there a summary of what to do? I've seen tires, driveshaft balance, pinion angle, tie rods, rear end.. etc listed as being root cause but is there a summary of what the fixes are? Does it depend on the truck?

 

The vibration is not that bad and I can feather the gas to help it. It actually drives great at highway speeds. Love the truck otherwise. A question for the community: should I live with a slight vibration or do I bring back to the dealer to fix? Will they make it worse? Should I wait until GM figures it out?

 

If I do have a problem down the road, I want to make sure that I've documented the fact that I'm having the same issue. That's one argument for taking it to the dealer.

Mine used to be a slight vibration and didn't pay no mind to it. In the last few thousand miles I've really noticed it and even my friend said something about it. Now anytime I get to 75+ mph that's all I can concentrate on is the vibes

If its not that bad and you can deal with it then don't let this thread get to you. Some people read so much about problems online that they end up convincing themselves that they too have the problem. If yours gets worse over time GM will most likely have it narrowed down. Right now GM is saying its a combination of parts that weren't manufactured to spec. So they start by checking/replacing the lowest cost parts and work there way through the potentially faulty parts.

Picked up the truck at 11 AM and took it for a 50 mile ride, including a little highway run. Right now it seems fine but I need to take it for a longer highspeed run before i say anything is or is not resolved.

 

Being Friday there was too much traffic heading to Cape Cod so I didn't get to really give it a solid test. I'm going to RI on Tuesday so I'll get a better feel for it then as I've made that trip many times and I know one spot that triggers it every time.

 

And Jesse D, if you are south of Boston and want to take a test ride, just let me know. I'd love the get an opinion from someone else who is actually experiencing the same issue.

I'd take it in to atleast get it documented if nothing else. If it is very slight like your saying, it could potentially be something as simple as the tires, improper alignment, etc. as some other people have found with their trucks. alternatively, you could be starting the same process many of us are dealing with now. Good Luck man.

I agree, anything that helps at this point will be a awesome.

hahaha I hear ya on the cape traffic, I was heading home from Boston at about 2:35 ish, and it was a typical summer friday on 93, I expected it to pick up a bit once I got past the split, but it didn't change all that much. That being said, yes I do live South of Boston, I would definitely like to see how your truck is now, and you can tell me how you think mine is. I will say that I feel that the majority of the vibration is more related to the engine than the rear diff, drive shaft etc (personally, I think that the way they have the engine mounting bracket is a bad design which causes alot of the vibration I have). I do think that i may have a couple bad tires, but again GM is refusing to do anything to my truck. but without any testing and work being done I refuse to rule ANYTHING out.

I'm really curious to see your results with the shackles. I've contemplated ordering a set, but for the price I'd hate for them to not help. If they work, you'll be our hero.

Wonder if we could get a group buy for those shackles if they prove to help lol

maybe we could get GM to use use them as a replacement part :P haha

Hopefully I end up being the hero and not the guinea pig that wasted 400 dollars.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Some Assembly is Required

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      Software Update

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
