The way silver spaceship described the vibration on his truck is exactly the same way my truck is behaving down to the tee almost sounds like he is describing my truck. And he is right it dose not always vibrant something triggers it, and I know it's the truck because I have tried the same stretch of road with my wifes Tahoe at the same speed and it doesn't vibrate. By the way I have had up to 4 people lots of times with me in the truck and sill dose the same thing. At first I thought it was just me but after reading silver space ship comments and describe exactly what I was going through, now im not crazy lol. What dose it take to get this truck switched out for another one dose anyone know? Or am I SOL on this one? Y do I have to pay 50k for something that is give me headache what can I do about this?

It's possible that the weight has nothing to do with it I just thought to my self on the way home what changed and that's the only thing. It might ride just fine tomorrow, it's unpredictable. One thing is for sure after having a engeneer test drive it and say its normal the dealer isn't going to do anything about it and I can't blame them. Plus the one I test drove did it too, I would say not quite as bad but very close at times.

I too have this problem on my 2014 silverado w/5.3 4x4 z71. Wicked vibration while towing an aluminum open trailer with two atvs. None under normal conditions nor when hauling a 4000 lbs camper. Trailer doesn't vibrate behind other trucks. During lunch I happened to sit next to two service technicians. They said their is a known prop shaft alignment problem with no know fix that they were aware of. If I am thinking about this correctly a light load squats the truck just enough to create the problem. But a heavy load makes it hard to notice. I love the truck but sledding season is on its way, got to get this fixed soon.

 

Oh that trailer is about 500 lbs plus another 1000lbs of atvs. Creating about 200 lbs of tongue weight. Vibration gets real bad at 55mph.

I have this very same issue on my 2014 Sierra 2WD. I may have a solution (theory) to why it seems to go away sometimes and return other times. I have noticed that on my truck the vibration will get better or worse as I am turning at highway speeds starting at about 65 mph and continuing upwards of 80 mph. I noticed the vibration one weekend on a trip and got the tires balanced the following weekend. The problem seem to be actually worse than it was when I took it in, so I started to really pay attention to it. I started noticing that it would be better occasionally and then worse. I hit a really long bend in the road and that is when I experienced the reason, at least on my truck, why it seems to be better/worse. I felt the vibration cycle from almost gone to really bad and then back to almost gone. It appears that there is a balance issue between the right and left wheels. As they turn at different speeds while turning, they are able to align with each other producing more vibration or offset from each other canceling out the vibration. It never totally goes away on my truck, though. I haven't taken my truck into the dealer yet but I plan on taking it in next week to see if they can check some things out.

 

On the weight subject, I almost daily haul around 4 other guys during lunch and still have the vibration though the speed in town is only 65 mph so I can't say if it is worse or better with the weight since it is only starting to vibrate at that speed.

 

Edit: I forgot to add that I have since had my tires balanced twice with no change to the vibration.

I had a '12 Grand Cherokee, that did the same thing. It drove me nuts. The dealer said that it was supposed to be that way. I think they just couldnt figure it out. I got tired of fighting with them so I traded in on my '14 silverado.

 

I have the LTZ and the ride is super soft, rides like a 80's caddy

So after not hearing anything from my local dealer for 9 days i decided to call and see what's the status on my truck. The rep told me that a Chevrolet engineer came down to check the truck. The engineer said it was the drive shaft and order a new and improved drive shaft and gets installed next Thursday, this will be the third drive shaft they put on. The engineer said he was going to put it on and test drive it him self so let's see how that goes.

I just had my tires rotated today and the vibration is still in the rear of the truck. The only thing that I can think that it is now is the axle. I will be taking the truck into the dealer next week to have it looked at. I will keep you all posted on what they come up with and if it helped or not.

Well, the dealer replaced the driveshaft Friday. Didn't do anything to help the problem. Maybe the 2014 Chevy's are supposed to vibrate.

I haven't experienced any vibration, certainly hope they figure it out!!!

And now it's on the back of a wrecker headed back to the dealer. Surging won't get over 30 mph. This has been one hell of a new vehicle experience.

Just curious, those who have the vibration what wheels do you have? I drove one with 20's and it felt different than the one I bought with the 18's.

    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that. 
    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
