I just had a wild idea. Does anyone here have access to a dyno machine? Put the truck on it, take it up to speed and see if the vibration persists, then try it in 4 wheel drive. Id be easier to get a camera under there with the truck on a dyno.

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

My 2014 GMC Sierra SLT shakes/vibrates when I tow my travel trailer. It has done it since new when I took it out with only 150 miles on the truck. If I ease into the throttle you don't notice it but if your start from a dead stop and hammer the throttle it will shake through the firs few gears. Other then that issue I don't notice a shake any other time. I am hooking up my 27' travel trailer in the morning and have an appointment with my dealer to check it out. It is definitely something related to the power train. If I never towed I wouldn't have know about the issue. I let you know what they say.

Well, after my buy back of my 2014 c/cab sierra all terrain I bought a Ram eco diesel truck.

My ram is at the dealer for a small paint defect repair, and they rented me a vehicle which happened to be a 2014 suburban which has a shudder and moan, and slight vibration at 40mph-55mph like my truck had.

This suv has the 5.3L v4 fuel mangement and 6speed with 3.42 gears?

With out a doubt I am convinced this problem is the transmission torque converter or pump or the out put shaft bearings.

This is why GM not willing to admit there is an issue, while they quickly roll out their 8 speed trannys.

Just my humble tech opinion.

Guys have mentioned this before but I'm not sure if anyone has actually tried to diagnose the vibration/shake on a Dyno.

I haven't seen any 2015 6.2L 8 speeds available for purchase but there's definetly a lot of 2015 5.3L 6 speeds with 3.42. So their not rolling them out that quick.

If you go to carsforsale.com you can view almost every new vehicle on any lot in the US.

 

Edit: I also believe it to be the transmission in many of these trucks.

I just took my sierra in today to the dealer for the vibration problem,just got it back from dealer last week for the same problem plus a few other issues. I went for a ride with service manager and got about 3 blocks away from the dealership and he said ok thats good enough take it back to the dealership. My truck was built 7/13 so its an early build and you sure can tell after a five minute ride in it. Im gonna give the dealership one more chance to fix this vibrator with wheels then I will have to take this further.

I hope they treat you proper, and make things right!

Keep all paper records each time, and keep a log book of notes of attempts to resolve your issue.

Good luck mine didn't get fixed no solution found bought back.

I have 14k worth of dealer installed up grades on my truck so they need to fix it. Im not gonna lose my a** cause they cant figure out what the problem is.

So the technician said there is defiantly an issue and he is talking to GM engineers before proceeding. He thinks it has something to do with axle wrap, the driveline or the rear end. It only shakes when I have a load on it and accelerate hard through first and second gear.

I picked up a 2014 silverado custom sport last month. 5.3 L - 3.42 rear. It came with polished 20s and Continental Crossconnect eco plus tires. After about 500 miles I notice a vibe in the steering at around 75 mph. Not real bad but it's there. Also cruising around local I sometimes get a vibe in the steering but not always. Most of the time the truck feels smooth. I only have 1200 miles on the truck so I wanted to see if it get worse or better. Also, was wondering if any one else is running the Conti's and if your getting any vibration with them.

What the heck are "Eco plus" tires? Low rolling resistance or something? Somewhat of an oxymoron with heavy 20 inch diameter rims.

Reading all of this (not really, but I did read a lot) reminds me of a 2000 Silverado I had once. Took me almost a year to get the dealership to replace tires on it. Shaked like the dickens at highway speeds. Turns out it had 3 out of round tires on it. 3!!!! Goodyears.... The first time they finally replaced, they did with Goodyears, and it still shook. Then I got firestones (off brand named versions) and it drove like a dream from then on.

I assume "they" is the dealer as GM is not responsible for non-OEM modifications (even if done by an independent dealer).

right before your arbitration hearing they will call you and offer a full purchase value trade-in credit towards another truck and you pay any additional cost if its a higher price.

 

at that time you can make a deal for them to transfer all your upgrades to the new truck and I would "assume" they will absorb the labor cost but then maybe not and you will have to pay the labor but that's still a decent deal.

 

short of that its up to you to remove everything yourself and then sell it or buy another truck you can use them on.

 

you are not going to get a penny more from GM then the cost of the truck the way you bought it in stock condition, consider the rest lost money unless you can remove it without leaving any damage to the truck from removing it because scratches and holes and anything else will all be depreciated at full retail body shop repair prices.

      OCI, not when but why?

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".

      OCI, not when but why?

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.
