Just bought a 2015 Chevy Silverado has bad vibration when your holding steady at about 1500rpms at 65mph comes and goes with light acceleration feels like rumble strips. Bought it on June 6 went in the shop on June 30 just got it back Friday July 17 and it's not better at all! They did a software update and the tranny and road forced balanced the tires. I know there is a lot of post about this but has anybody had any luck with a fix at all? If not I guess I just wanted to welcome myself to the vibration club!

Ok guys, i finally got the problem fixed after several visits to the dealership. The vibration problem is the ring gear and pinion gear which i suspected in the beginning . Chevrolet had an issue with

Had my truck in for the 2nd time today and they tightened up body bolts, checked complete front end, box and exhaust system. They test drove it and still vibrates steering wheel starting at about 50 M

So got my truck back yesterday. Diagnosis: there weren't any wheel weights on any of the tires. Guess they forgot to balance the tires at the factory. So for now, vibration and shaking is unnotice

Couple questions for vibrating GM’s,

 

Has anyone tried to put their truck in neutral while on the highway at the vibrating speed? Does it continue to vibrate with the engine at idle while coasting?

Does everyone with this vibration issue have a secure lock nut on all four wheels?

Whatever it is, has now carried itself from 2014 to 2015... Which means GM does not have the answer

that would be correct my friend

I've been wondering if anyone has put a confirmed "vibrator" on a stationary dyno,get it up to speed(70-75) and see if they can replicate the vibe without having to go on the highway.Would be smooth/consistant ride,unlike highway where little bumps can set it off,Seems like this method could narrow down the possibilities.If it still vibes on dyno,that would eliminate anything up front (Tires,wheels,Smooth Road Shake from the new electric power steering,suspension,aerodynamics) narrow it down to the rear tires/wheels,driveshaft,rearend gears/axles,transmission.....Still chuckle about the guy who was told it shakes because he put running boards on.

So I did more testing in my truck yesterday before dropping it off at the dealer again, The highway was pretty free for a change and I was actually able to get up to 82MPH for the first time in about a month, and I did not have any SERIOUS vibe issues, just the light vibe I get at all speeds (no its not standard road imperfections) , It did continue to have a worse vibe/shake when going around a curve on the highway at speeds of about 45+ MPH. The AFM still sucks, Ironically they gave me a Tahoe for the loaner and I only noticed the AFM vibe once in it, all other times it was flawless (audience gasps here) and guess what else.... The radio actually works properly (wispers among crowd in shock). So when I dropped it off, I specifically requested that they examine the steering position control sensor (figured what the h*ll, maybe they will find something wrong with it and the "smooth road shake") I also specifically asked them to roadforce and re-balance the wheels (figured what the h*ll, maybe I'll get lucky and it will help). They looked up the Service Bulletin for the Radio and were surprised that I knew about it when they didn't (So I thank you all here, please take a bow), we already know that the software is up to date, but they are going to check again, and they said they would try to play around with the radio again to see if they can figure anything out, but I'm not holding my breath.

 

So when he read the TSB, he said that GM is blaming it on obstructions such as buildings and poor signal quality from the provider. I said "thats a load of sh*t, these stations have been around here for years, and I've never had issues with them before, even in my old 2007 with the stock Ford/Lincoln deck that I traded in for this" and he agreed with me.... further prof is the Tahoe, It has not issues picking up the same stations that my truck can't do.

 

He is supposed to call me this afternoon about anything they find, what they can/ are doing for it, and when I'll be able to get my truck back. I'll keep you all posted with any findings

thats hilarious about the running boards

I have coasted in neutral, and ran it in 4th 5th anf 6th gear at 70 mph. Vibration is unchanged in frequency or amplitude.

Ok guys, i finally got the problem fixed after several visits to the dealership. The vibration problem is the ring gear and pinion gear which i suspected in the beginning . Chevrolet had an issue with the cuts of these gears which they have yet to announce. Have the dealer check the backlash on the gears and they will find it is not in tolerance by Gm standards. Gm will send a replacement kit that has been corrected. You will need to be insistent on this process. This isn't a cheap fix for Gm and they will try to beat around the bush with the tire balance smoke screen. Keep calm but firm and it will go along ways in solving your problem. Hope this helps guys and be safe in your travels.

Had mine replaced on my 2014 GMC Sierra SLT...after multiple trips to and from dealer and 4 new tires. The issue persists. Glad yours is finally good to go.

What speed was your vibe at?

 

Glad you got it fixed.....there is hope!!!

Speeds were 40-50 minor and 72-82 major mainly 75-77. Also curves and light accelerations

Congradulations!

 

My 14 Sierra Dbl Cab got this fix 11 months ago. Cured my vibration. Several others got this cure with no change in vibration.

 

Guess you are lucky, if not a discoverer!

It's good to hear that there is possibly a light at the end of the tunnel! I need to take mine back in even though the dealership claims the issue was resolved by balancing the tires. For the most part, I drive the same roads every day so it's hard to distinguish between the road being bad or the truck. But took the truck out for a nice drive the past two weekends and definitely a vibration or shake that starts around the 70mph mark. Lately we've been calling the truck, the Vomit Comet. It got so bad driving 100 miles in it this past weekend that we literally stopped off at a stretch of car dealerships and was ready to trade it in for a Chevy 2500 Diesel and ( gasp ) even possibly a Dodge Diesel. Lol. On the advice of the Chevy dealership, I'm going to take my GMC to another dealer service department that is willing to further troubleshoot the issue as the one I normally go to just wants to keep blaming the design of the truck and bad roads in California. You would think that they would've put new tires on after riding around unbalanced for 1 year/8000 miles instead of rebalancing them with the hugest wheel weights known to man. I'm wondering if the ring and pinion gears will help resolve the problem and maybe a new set of tires. We're pretty loyal to GM when it comes to trucks but if this goes unresolved, it might be time to jump ship.

      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

      By Grumpy Bear · Posted

      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.
