Shake or Vibration Issues

[Pinnacle]

How can that be true? I have a 1500 crew cab 4x4 and it is perfect at any speed and not even one problem with the truck.

 

And if your statement is true, how can almost 80% of '14 owner state that they love their truck and have "zero problems" in this thread? http://www.gm-trucks.com/forums/topic/159890-how-satisfied-are-you-with-your-2014-gm-truck/

 

Here's another thread... "Keep or Trade it in?"... 85% would keep their truck http://www.gm-trucks.com/forums/topic/161029-poll-keep-or-trade-your-2014-back/?hl=trade

 

Don't get me wrong here. I know there are serious vibration issues in some of these trucks... but to say all 1500 crew cab 4x4's have this problem is way overstating the problem IMO....

 

Yourself and fondupot are very fortunate to have trucks that work as they should. In that sample about 80% or 206 people said they have no problems, but we have alot of people out there that do not post on this site.

 

I have asked my friend who works at the biggest Chevy/GMC in my city about this issue and he has informed me that more and more are coming in. In my city the speed limit is 100Km/h which is 62 mph, the problem occurs at 120 to 130km/h and when people come in to report the problem they immediately get turned away because they are breaking the law, as you cannot go past 100km/h, the dealer says you broke the law nothing we can do! Alot, of these people are just sitting ducks here in this city atleast.

I would love to think that more than just a few trucks are vibration free.. However after driving a few today and speaking to the shop foreman and him telling me he has noticed it in all of the ones he has driven makes me think otherwise. I would love to find one that doesn't do it so I can buy it.

I would assume the majority do not vibrate. Mine is like riding on a sheet of glass smooth as silk.

I'm sure some ride very nice...but others ride terribly. Mine rides very poorly with the hop / wobble starting now around 55. I used to think temp effected it more, and it might but truthfully I dont care anymore. It needs to be fixed and I dont have time to worry about WHY it's defective. It just is and has to be fixed, and soon. The loaner 2014 double cab I got, with a V6 shook worse than mine. The dealer tells me they have many people coming in with the same problem as mine and they're still trying to figure it out. The GM engineer that looked at mine says it's tires, and they're putting in a new drive shaft design in too...next week. I'll let everyone know here if those two items are the magic fix. So no, not all 2014 trucks have these shake issues which means it's not a design issue and therefore is fixable and must be fixed for the customer. Mine goes back for the 5th time next week when the new tires and shaft show up. That's FIVE times. I have an open case with GM on the matter so we'll see what trip number five results in.

So if the truck you ordered arrives with LPO 22" wheels and there is a vibration issue, the issue is the wheels/tires? Even if they are road forced balanced? Then you replace the wheels and tires with a higher quality (cost twice as much) wheel/tire package with hubcentric spacers that road force balance at 10/12/12/12 and the vibration/shake still continues. It's still the wheels/tires? But only most of the time, not all of the time....I have gone as far as having my best buddy driving alongside me on the highway (23 years as an Army Motor Sergeant) in order to conduct a visual inspection. Nothing shows that its out of balance or round....go figure....(stated with sarcasm)................

I've worked with an uncountable amount of Motor Sergeants and Army light wheeled mechanics. I would trust them with my life.... But a HMMWV or LMTV or any tactical vehicle isn't a Silverado. That's Tahoe person's problem IS wheel/tire related.

Hello again,

I wanted to send this forum an update to my vibration issue on my 2014 Silverado. I originally posted sometime around the first of this year. I tried to find it but there are too many to look through now. Anyway, on my last post I stated that the dealership had replaced the drive shaft and that it cured the problem. That was not the case. The truck still vibrated from speeds 60 - 75mph +. My dealership actually agreed to buy the vehicle back. I had to ordered another truck exactly like my original, 2014 LTZ long bed, 342 rear end, 4wd. It took the truck 10 weeks to come in. I had the Michelins on my original truck installed on the new truck rims and took the truck for a test ride. It seemed to ride great. So I proceed with the deal. I immediately went on a trip and the truck still vibrates exactly like the other one.

So at this point I can tell you guys what doesn't work:

-Road force balancing to with 12 - 14 pounds max.

-Michelin tires

-new drive shaft

-New Truck

The service manager at the dealer I am working with also let me choose several trucks off the lot to test drive. Every crew cab truck I drove had vibration that started around 70 mph. Some were worse than others. Even though the FSE's think that replacing the tires or road forcing to low number will solve the problem... it's not the tires and it's not the driveshaft (mine was replaced also). The last FSE that drove my truck thought the Hunter Road Force machine at my dealer was defective so he drove it 20 miles away to another dealer to work on my truck. I just got mine back after being in the shop for the fifth time. All tires were road forced at 10 or lower and as soon as I got up to speed on the interstate it started shaking. When I told them it was still shaking they then blamed it on "road input." I don't know what else to do other than filing a defect notice.

Yep - mine is smooth as silk also. And no it's not for sale!

 

BTW 20" stock wheels and Goodyear tires. 5K miles so far

Yes, concur. HMMWV, MATV, LMTV, are different, but fundementals are not (and not all motor sergeants are the same, but this one is still building/rebuilding boats, cars, and trucks and can troubleshoot like the best of them). The wheels/tires he was talking about are LPO wheels from GM. Mine came with LPO wheels and bridgestones (LPO's are lug centric). That is what the common factor is.

 

I had mine roadforced at a reputable tire shop where all they do is tires, and they have the best machine in the business of roadforce balancing (Hunter Road Force GSP9700). When you get numbers like 10/12/12/12 then your talking about tires not being round on a microscopic level, the wheels and tires are as round as round can be.

 

The shake I am getting, and most others, is enough to make the back end of my truck seem as if its going to come off. When looking through my rearview it looks like my snugtop lid is coming off.

 

To have a shake like what I am experiencing is a whole other issue. You should be able to see the wheel/tires movement if its the culprit. Visual first, next would be answer why the wheel/tire combination is only out of round at a certain speed segment (73-85 for me).....In the case of the Yukon, it could very well be a bad mount/balance, but with a lug centric wheel you would definately be able to see that its not balanced. (No sarcasm added). Mine is going into the shop this coming Tuesday, and they are providing me a 2014 SLT crew cab until they figure out what's going on. Or at least I will get to drive a vehicle that does not shake/vibrate.....hopefully.....

 

Anyways, my point is that just changing the wheels/tires could exagerate an issue that was earlier hidden. In many cases posted on here, both GM and bystanders are pointing to the easiest thing to point at. Blame the wheel/tire package added. When in fact the wheel tire package came from the same place you got the truck. If the truck is so sensative that just changing the wheel/tire package could screw up your whole vehicle, then why have the option. If the truck is that sensative to change, just wait until it changes 10 degrees outside and your going to have other issues. The list goes on and on, but the reality is that there is something wrong, and roadforce balancing 2 or three times isn't going to change the problem when it's not the easiest thing to blame the issue on. I have sat back on this forum and just read the reply's and not put too much input in. But, yesterday I just had to post a statement because it's just not a good idea to arm-chair quarterback an issue when you don't have all the facts or haven't done the research as to the exact case involved.

 

BTW, both my friend and I are 21+ year US Army retiree's and would like to say to you....Thanks for your Service!

Do you have 4WD? Im trying to figure out if 4WD has anything to do with it vibrating. Also you have 3.08 Gears?

Yes. Z71 4WD 3.08. Like a limo right up to 99mph when the governor kicks in

I have 2WD and vibration.

What is your build date? sorry for all the questions just trying to gather some info

[MJFlores]

I believe it's already been determined that there's no correlation between vibration issues and build date, body style, engine, rim size, or power train. If it's a 2014 1500 it may or may not have the vibration problem. Some of the first 2014's had it....and some of the newest ones on the lots right now have it. Keep in mind that this thread will be a year old in a few weeks with new comers popping in regularly. We should all get club jackets or something.
