Shake or Vibration Issues

[14SLTZ71]

I have looked through these forums and can't seem to find the link for adding phone contacts to the radio favorites, does anybody know where thats at please? I can't remember how I did it.

Just google this and you will see a link to a video of how to do it.

Here is something I read at another forum, this sounds like the 70-85 mile an hour issue to me.

Add on the fact that the transfer case chain was redesigned as well could be the source of some if not most of our vibration and shaking.

just saying

 

Re: 2014 silverado ltz vibration

 

It is not wheel balancing. We have had several of 2014 trucks with vibrations, both Chevy and GMC. One of our technicians found the teeth on the ring gear in the differential were different lengths. Supposedly fixed a few. Mine vibrates like crazy. I can feel it the instant I hit the gas and different speeds as high as 85 mph. I haven't had mine done yet as I don't want to throw parts at it.

 

There are a lot of trucks with this issue. Not sure if the ring gear is really the issue. If it is, they better do something about it. Either a service campaign, or recall. My double cab was less than 500 units in production at Fort Wayne and the assembly quality has been horse $hit. It should never have left the factory with the issues my truck has. Many of them are because of poor assembly. My truck makes me embarrassed for anyone who works there.

Mine is also from Fort Wayne. Build date 6/14. Still pumping out bad ones.

Mine is a 7.14 build date and mine comes and goes. I feel like mine it more road feed back then anything. One stretch of highway it is smooth and then another I have vibration.

I can not believe thst GM has not figure this out by now, knowing how this is effecting their product and sales.

This is so frustrating to know that others are still buying broken trucks.

This rack and pinion steering unit was not designed right in my opinion. There has been alot of issues with noise coming from this unit. Could the road energy be transfering and damaging this electronic shake control rack and pinion unit.

I am not really sure it's affecting their sales, even if someone buys one and trades it in GM gets their money, and the majority of people on this forum say they love their truck and would definitely buy it again. This is probably why GM is acting like this issue is just isolated incidents here and there, which makes it easier for them to treat this like its not a big deal.

I have an angle finder from the days when I built my rock crawler. It's now on my to do list to check the factory driveline angles next weekend. I will post up what I have and see what I think. I've worked on enough large custom trucks. my 4runner has a CV rear shaft, and Dana 44 front axle. Leafs all around. built in my driveway. 38" tires. 5spd manual. Winch, custom bumpers I built and all. Detroit lockers F&R I installed. I took that truck up to 100mph ONCE to see what it would do. Smooth as glass!!! So how can I build a truck in a driveway that's sitting on 38" tires, leafs at all corners that runs 100mph and smooth and GM can't build one at a factory to drive smooth??? HHMMMMM??

 

The new Tundra looks good now. If they offered a locker in the rear and got their MPG's up with the others they'll kill everyone. The tundra needs a 8spd trans and direct injection to help with MPG's. Maybe offer a 5.0L engine to help with MPG"s also. Let's face it, my 5.3L is great. It's a truck. not a race car. Operating costs go into your price that you pass along to the consumers. Trucks are tools. That's why I bought my truck. The GM trucks make the most business sense. Better warranty, MPG's which equals you can lower your cost of bids and get more jobs in construction.

Maybe all of us should call gm on the same date and time and mess with them like they do with us....

Holy Smokes what a thread.

 

Mine is a 14 sierra 4x4 Z71. Vibrates randomly from 74 to 80 or so mph. I took it in about 10k miles ago and they did a 'road force balance' and charged me for it. Did no good. I haven't driven it on the interstate enough since then to be irritated by it. I now have 19k on it and am travelling on the interstate again (GoNoles) and it sucks.

 

Judging by this thread, looks like I can forget getting it fixed.

near as I can tell nobody ever really gets it fixed they just try things like wheel balancing that reduce it enough so the average person doesn't notice its still there or they don't ride on smooth enough roads to feel it.

 

they don't balance the tires on these trucks so getting a good balance often takes 40% of the vibration away and the rest is from something else and that's what they have no idea how to fix.

 

if you push it you can get a buy back from GM but you have to meet the lemon law requirements and get a lawyer to go through the process which takes months then they buy it back with depreciation for the miles you put on it. but that's often going to be a much better deal then if you trade it in on something else

 

bought my truck Aug 28, 2014 and its been in the service dept for 3 unsuccessful repairs for the vibration issue and they refuse to look at it again after just rebalancing the tires all 3 times, will try a different dealer tomorrow and if they refuse its lawyer time.

I had this issue too when I first bought my truck. I picked up my silver ice metallic 14 LTZ Silverado in June. I immediately noticed an intense vibration above 75 mph. It was really bad and my first though was that it was something mechanical in the drive train.

 

Turns out the vibration was caused by the wheels not being balanced correctly. Apparently the truck left the assembly line without them ever balancing the wheels. As soon as they balanced my wheels correctly, the vibration went away. Smooth as a cadillac now.

And tell them.... "You can get anything you want at Alice's Restaurant".

its called a class action lawsuit, maybe its coming soon if they don't stop saying trucks are supposed to shake and vibrate just because their "so-called" proof that its normal is that all the other trucks on the lot are equally defective and vibrate as well

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?
