Shake or Vibration Issues

this caught my eye

 

"Adjusting the U-joint working angles on the current full-size trucks is normally accomplished by moving the center bearing up and/or shimming the axle pinion up about 2 degrees. It is generally not necessary to move the transmission up or down."

 

so it sounds like they commonly come with the wrong u-joint angles from the factory. I doubt if this could be all it is or they would have a service bulletin fix for something that simple but maybe it is in the tranny angle side that a shim wont fix as someone mentioned.

 

do all trucks have the transfer case thingy or is that just the 4 wd ones?

 

 

i wouldn't be surprised if the tranny angles were off. There is another bulletin out there that is a fix for vibrations when he truck is idling. I had it done on my truck, because when I would come to a stop it would vibrate, but just when idling. I didnt have any "at speed" vibrations.

 

They have to reseat the motor and the trans and recenter everything on the mounts. So that makes me think if the trans is off center, it could be causing issues.

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

Just dropped my 2014 GMC Sierra (w/ 1400 miles) at the dealer to start investigating this vibration issue. I will say that the vibrations I am feeling sound minimal, especially in comparison to some of the posts I have read on this forum. Mine are mostly in the seat/floorboard and are only felt between 70-85 MPH.

 

The vibrations on mine also seem to come and go. Some days on the same stretch of road it fine, others it is really bad.

 

Praying they can at least minimize it to a tolerable level without multiple trips, runaround from service dept, lawyers, buybacks, etc.

 

Will keep everyone posted on the findings!

Well within seconds of me posting the last post above, the dealer called and said my truck was ready. They roadforced all of the wheels and tires. One of the tires was replaced and the other 3 wheels were re-balanced. Took it up on the highway and the truck does feel much better. There is a slight vibration/bumpiness at 73-75, but I am thinking that is from the roadway. Took it up to about 88 mph without any issues.

 

Hoping there aren't any further issues!

I hope so for your sake but I think you will find that its still there and it just needs to be driven a little to show up or find a smooth road for you to notice it.

 

mine is sometimes very slight then a mile or two down the road it starts up again. seams to get stronger after things warm up and not be that bad when the truck is parked and hasn't been driven and things are cold

 

just left the dealer for service #4 for vibration and he said its a known issue for "some" trucks but GM has no recommended fix for it so they will call me when they know how to fix it, otherwise they consider it "normal" to vibrate

Well mine is definitely temperature dependent and seems to occur when temps are between 60-80 degrees F outside. It's been fine all summer in the high heat and the truck was fine during the cold winter. As I've stated in the past I started to notice the vibration in the spring as temps started to go up but then early June it went away and never came back until this past week when temperatures dropped to the low 70's during the day and the low 60's at night. I'm still thinking it's tire related though, but affected by temperature.

Guess I spoke too soon.....on my drive home, noticed it again, but feels like it is even worse. So weird that it is an issue that just seems to come and go without rhyme or reason. Got a call into the dealer to take it back in.......... If I had known I were going to have these unsolvable issues, I would have never bought the vehicle.....feeling pretty sick right now on a $50K+ truck.

 

We'll see what happens next!

sorry to hear it but im not surprised at all, the only known fix for the vibration issue is to replace the truck or get used to it and learn to ignore the vibration.

 

start documenting everything and do your lemon law requirement then file a claim.

 

its up to you if you want a replacement or a refund

So in order for GM to offer me a Buy Back, do I have to contact a lawyer regarding the lemon law? Or can GM just offer a buy back? Please advise.

no you don't need a lawyer, I talked to one and he said I don't need a lawyer, just file with the BBB and the lemon law process takes care of itself

 

GM will not offer to do anything until you file lemon law, then and only then will they try to resolve this with you to preserve their reputation and BBB rating to avoid bad press

 

go here and file https://www.auto.bbb.org/lemon-law-complaint-form/

 

but make sure you have the number or repair attempts to qualify first or they will tell you the dealer must still be given those chances to fix it.

Does it have to be 5 attempts to fix the vibration? I thought lemon law was 3 attempts.

When people post can you please give us more info on the truck like make, model, type ( crew cab etc), 2wd or 4wd, rim size and brand of tire, month and year it was built. maybe we can narrow down which style is more of a issue or maybe it's just hit and miss on all styles

General Motors told me it was pretty much normal and they wouldn't do anything else to it. Mine was in the shop 6 times for the vibration at 73-75 mph and I wasn't about to take it as normal. If it was normal ALL trucks would do it and they all don't. I filed with the BBB and it took roughly 3 weeks total to close the deal on a new truck.

 

Yes I took if for a good test drive on the interstate with the Service Department manager in the passenger seat. My new truck which I have had since Saturday is such a better ride at this moment. So much happier.

 

Don't let them off the hook I truly beleive that GM is taking care of the sqeaky wheels first and if you don't complain they won't do a thing. They did a trade assist and covered all the depreciation. Do it quickly while there are still 2014's to pick from. Everybody is saying right now wait and get a 2015 that is reading this but you will have to pay the difference between the cost of your 14 and the new 15. Good luck and keep up the fight.

I'm a auto tech for a G.M. dealership in P.A. I'm currently experiencing this same problem with a 2014 Silverado,four wheel drive,automatic, with the crew cab if that's what you want to call it. It currently has approximately 20,000 miles on it. This vehicle also has Goodyear Wrangler tires on it,20 inch and going down the road frfom 68 m.p.h and up I can feel this shake in the vehicle. I have road force balanced the tires,switched the driveshaft with another stock unit and then i tried another set of tires that were Goodyear Eagle tires. I have replaced the left side axle,measured axle runout at all four hubs,i have removed all rotors and cleaned them with a rollock wheel. This truck is driving me insane,I currently have over 20 hours trying to figure this out, I seriously don't know what to do next the customer is being very patient whichis nice of them they have been in a loner this hole time. We have had this truck for about a week and a half. Help me G.M help.

      Ok I missed that part that yours is a GM. The strange part is that the choice for year ranges and within the year of 2026 is different on the Sierra then on the Chev for some reason as I am looking at my tool at the Sierra choices. Now I am guessing you see as to your sensor part number as it may be different on your truck for some reason and a call to GM should get you the part model number of the sensors you should have as well as which MHz your sensors are. I know mine are the ones as per what I listed but there are other choices in the Autel and got me wondering if by some chance they put different ones in your truck. Having said that, did you try using each of the choices starting from No 1 and going on down the list, not sure if that would mean shutting off the engine each time and resetting the tool and going at it again each time. Also I thought of something else which may sound retarded but if there was some stupid chance that the chev choice would work. The reason I say that is that the Sierra is showing a range up to 06/2026 for the various choices of sensors it could be where as the Chev has one choice that has that 12/2026. By the way it is possible to not run the truck and you may know that as per not pressing the brake but pressing and holding the start button for a few seconds and it lights up the dash ( its called service mode ) but that sucks battery power and if it were me doing it that way I would be throwing on a decent sized battery charger before doing it that way as killing your battery won't make you happy at me at all !.    Like I say, just a thought to try the Chev choices if you have already exhausted the Sierra choices but first it would be nice to know for sure what exact sensor model and hertz your truck uses as I assume only those choices that mention the sensor would work unless a choice that does not mention the sensor model would somehow work. Its frustrating when one is trying to use tools like this without the experience of the tool and the vehicle, as I am sure dealer techs themselves struggle with it when starting out or a new model year comes along that is slightly different.

      I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?

      Its just that it worked on 2024 trucks on this forum and my 2025 model truck, unless GM did something since that point to screw up access or Autel has a bad update. I haven't had need to use my tool since last year when I did the changes to the placard pressure settings and since then I updated the software on my Autel but have not plugged into the OBD so hard to say if I would get a surprise as well.    All I know last year when I bought the Autel I was warned to be sure to update it before I tried using the unit as they said who knows how long ago unit itself was actually manufactured as the software could be way out of date.

      And so you had gone through the process of registering and updating the tool and so on ?. All I can say is that on the front page as the tool fires up you go to advanced mode, then vehicle model comes up and you choose Silverado ( not the DRW or EV  since your a single rear wheel ) , then I think its choice 2 which is 07/2021 - 12/2026 ( 433mhz 13542523 ) as that is the series of tpms sensors and then go down to choice 5 which is tire type/pressure selection. Hit yes and it says to connect to OBD port and turn ignition on.    Having said this, I updated the software in my tool lately and these year range choices look different from the past due to them doing some updates it would appear and I have not connected up to the OBD port since last year so hopefully I am not in for a surprise with them screwing up the software and that it won't work on my truck anymore either.    So my question is, when you plugged into the OBD and started your truck it had that message on the Autel screen "vehicle not supported" ?. That does seem odd as tire shops would be pissed right off if hey can't use their tool on the model year after mine that in theory is supposed to be much the same truck ... unless GM did some change in the computer system to block certain things from access.

      Understanding and using modern scan tools is its own body of knowledge. I had little hope that would work...programming access to the BCM is probably required and that is not easy for us consumers. Expensive scan tool, GM programming subscription, online authentication, etc.   It also may be a matter of finding the right dealer to program it for you. Flashing a modern BCM might be a little too advanced for most tire shops.
