Shake or Vibration Issues

Silverado-Hareek · October 29, 2014

Thanks Silverado-Hareek, I guess it may be inherent to the truck.. I had a 2007 Jeep Wrangler that did not transmit this much thru the steering wheel. The harmonic is constant and feels like it could put your hand to sleep after several hours. Do these things have steering dampers/shocks?

Hmmm ok yeah my vibration is not that severe. If it's making your hand feel like it's going numb, the first thing I would do is get the front end checked out for any loose pieces or parts and get the balance checked on your tires. I'm not sure if there are steering dampers or shocks but I do know the electronic steering system is supposed to counteract road imperfections to reduce the transmission of vibrations to the steering wheel....I don't know if that is done mechanically or electronically within the steering system but I've seen that feature discussed on the forum.

Is this much rubber wearing off onto my driveway normal? This is from the stock Goodyears that came on my truck. I have had it for exactly 2 weeks now. Taking it in tomorrow for second time, for vibration issues. I've never had any tires make this many marks on my driveway, other than the 8 year old trailer tires for my boat...and even those didn't make such dark rubber marks...

You likely have a bad ring gear in the differential. I had the same exact symptoms from 40 to 50 mph (max. @ 45) and gear was way out of tolerances. GM replaced and I'm as smooth as silk since...

Do you mean the transfer case? My truck is a 4x4.

Definitely not normal and this confirms my suspicions and what I've read about the Goodyear SR-A tires...that they wear down quickly and are generally junk tires.

My 2014 has vibration at any speed more noticeable at speeds over 45 ,up hill accelerating, down hill decelerating it's at it's worse. I have taken it to the dealer 3 times with nothing done but road force and balance performed. First two times my truck was not driven a single mile! I have 15 wheel weights on one wheel? My service department says my truck rides as well as half of them on my lot? $42000 for a truck that is suppose to have a vibration and I can't use auto four-wheel drive on snowy roads? In auto four-wheel drive the vibration is 10x as bad. Why?

Yes me. And I can't pinpoint the cause. I suspect the tires are the problem. I noticed it mostly back in the spring and then it went away around June. Since then I haven't had any vibrations at all except for 2 specific instances driving to work in September. The fact that it comes and goes and seems to be related somewhat to the outside temperature has me leaning toward the tires. How long it sits without being driven is possibly affecting it too. The truck drives great otherwise when I don't feel the vibrations in the steering wheel.

I will add though in general, with the stiffer suspension on these trucks, I personally feel more of the road than I did in my 2007 Silverado and that's after driving 3 different 2014's that didn't have vibration issues. So while there are vibration problems that people are experiencing, I think the combination of the stiffer suspension and the electronic power steering together transmit road imperfections to the driver and passengers more than the GMT900's did.

You can see my truck specs below my avatar. I have Goodyear SR-A tires that came with the truck. As soon as they're ready to be replaced, I'm getting either Michelin AT2's or BFGoodrich T/A KO's.

I don't think it's your tires, I have the same issue with mine (felt more in the accelerator pedal and floorboards though) and when I put michelin LTX M/S2's on it the problem didn't go away.

Edit: I believe the vibration in my truck is being generated by the transmission.

15 wheel weights????? Time for another dealer!

I don't feel anything in the floorboard or accelerator pedal. Only the steering wheel. I do have a minor vibration in the passenger seat and center console but my 2007 did the exact same thing so it's hard to tell if that's even an issue or not. Right now, the only thing I really feel in this truck is the occasional vibration in the steering wheel. I also feel what can be described as back pressure when V4 kicks in. I'm not sure if that's related to the engine or the exhaust but I definitely want to modify my exhaust soon and remove the resonator and the flapper valve.

15LTZZ71, I get what your saying about the accelerator also. The steering wheel and accelerator are not all that bad but it definitely is a harmonic resonance.. I have not seen any solutions anywhere. Something in the driveline would resonate thru the truck. I can't imagine GM does not know or is reluctant to fix these trucks.

Maybe it is your tires then.

_{I'm also a victim of the dreaded vibration, just as most others describe, 2014 SLT double cab, 20" wheels, 3.42. Dealer first tried the balancing act, replaced one tire, no change in vibration. Never a fan of Continental tires anyway (had tor replace all 4 continentals on a 2009), I went ahead and had four new Michelins installed - still no change in vibration. My truck has been at the dealership since this past Friday, an GM guy was supposed to take a look at it - I got a call today that they are replacing the entire rear end, something about a drilling error in manufacturing allowing the axles to float from side to side and that is what causes the vibration and why it is intermittent - we shall see.......}

I promise my fix will work for anyone here-

One of the early birds from this thread and I have kept up with it and all of you. After going through the wringer as many have here including new tranny, drive shaft, 3 sets of new tires, new seat brackets for a sliding seat, I through in the towel 2 weeks ago.

Took my truck to ford dealership where they bought my tx edition for 28k with 26,0000 miles on it, 2wd and traded it in for a 2014 f-150 super crew 4x4 with 17 miles on it for 29k OTD. I am beyond happy that my nightmare is over. The mental hell of being in that truck infuriated me and every time I saw a GM dealership I want to drive right through it. I have owned almost 20 silverados and WAS a loyal customer. WE bailed you out with our money and gave you a second chance. Obv no lesson was learned as GM stills runs a shit business. I know my bitching on here will fall on deaf ears and not changed shit. But I do have enough money to choose what I want to drive. I will never buy from GM again after this. EVER.

If any one else is interested, they are cutting the '14 f150's way down ( almost 20k off sticker ).

This being my first ford ever, I am very impressed with the build quality of the truck. I could of waited for the '15 model but was not interested in buying first year redesign. I liked that this was the final year of this style as the kinks were all out. Truck drives night and day better. NO VIBRATION. Even when I put on my BFG 275/65/20 all terrain so's on, no vibration. Transmition has nice firm shifts without the shitty lag that would slip and catch on a daily basis with my shitverado.

Go get a good trade number and get out while truck is still relatively new. Shit aint changing boys. You cannot put a price tag on piece of mind.

Good luck to all of you and I'm sorry you , we, got pissed on by a bunch of greedy ****s.

IM GOING TO ENJOY WATCHING YOUR COMPANY FAIL, GM. **** you-

$20,000 off sticker???!!! Where is this at?

Was the deal your truck and $1000 or your truck and $29, 000?

Wait so you got a new transmission and it still didn't fix it? I believe you are the only one anyone here has heard of that had the transmission replaced and people were speculating the tranny has to be the issue because its the only thing that hasn't been changed yet on any of the un-fixable trucks. That's truly alarming if it's still not the transmission either.

Took my 2014 Lt back to the shop yesterday. They took it for a 6 mile ride with nothing but a teçt 2 in hand took a few snap shots and said that my herts readings was 0 to 10 and ten is the highest level within GM spects. They haven't checked any runouts on anything. I watch every move while my truck is in the shop and no one has ever even looked under my truck. Then I'm told that it is my responsibility to get a GM rep involved that he cannot do this. I have been trying to resolve this for 12000 miles. Does anybody have any ideas about who I need to contact? I have a GM case number but all this has got me is a phone call every Friday at 4pm asking me how my truck is doing for the last 5 weeks!
