I just got another call from GM and the dealership stating that they are STILL waiting for this darn PICO scope to measure the vibration. A quick search on the internet and I did find this article on the GM Techlink site. While I don't think this would address my exact issue, I thought it was interesting. Sorry if this is a duplicate post.

And here is some information about how they do or SHOULD be doing a diagnosis on the vibration issue

well I got a voice mail from my dealer saying that someone from GM came in and drove my truck and there is nothing wrong with it.... Im feeling the tight torque converter which is designed that way so I get better gas mileage.

I have a 14 Silverado crew cab 4x4 and I have a vibration in pedal and floor when I am steady on the gas and it gets really bad when I hammer it on the interstate. Does anybody have a definite fix yet? I can't seem to find one. I also had the shutter at 30 mph when slowing down. I removed clips from rear wheel studs and got rid of it. Now I just need a fix for vibration. I have a 2.5 rough country leveling kit with new blocks in rear but from what I have read this should not be a problem, at least I hope not. I am planning on changing rear blocks back to stock to see if it goes away.

Let' see. "Someone" came and drove your truck. "You" weren't afforded the opportunity to be there. "You" don't know who "Someone" is. "You" do not know what specific expertise "Someone" has; but, since "Someone" was from GM, they must be right, you must be wrong, you cannot discuss the matter with "Someone" but since "Someone" is from GM, the case in closed in GM's favor. Maybe you could have "Someone" from Ford, Dodge, or Toyota drive the truck...wonder what they'd say.

 

You see nothing wrong with this picture?

I just got my truck back from the dealership for this issue. they had it for 6 days and balanced the wheels and replaced the driveshaft. they also tried to charge me for the balance but I refused to pay. they let it go after discussing for a few minutes. I then drove it to work with the same vibration I had 6 days ago. I called them and explained. now they are saying the tires are to blame( flat spotting overnight) . BS I say. so I googled 2014 Silverado vibration and found this thread on this site. didn't read all 248 pages , lol, but I now realize I am not alone. not good. one thing to note on my truck is the vibration is much more intense when the truck is cold eg: parked over night. after 10 minutes on the hwy its pretty much gone. 20" tires btw.

For all you members out there with Shakerado's. Ford has Vibrators too, I decided to make a video today showing the vibration of our new work truck, 2015 Ford F250. If I had a choice to buy a new truck it will be Ram of Toyota from now on.

well that's a new line of BS, at least they are being creative with making up new lies that don't make any sense.

 

with me they said since I drove a regular cab short wheel base truck for 37 years straight, obviously I just don't understand how short wheel base trucks feel and that that's just the way trucks ride lol.

This is the e-mail I received from today from GM....

 

 

I also received an update from the District Manager over the dealership. He
stated that he was the driver of your vehicle yesterday, and he provided the
following information:

"I drove this truck today for vibration complaint. I did not feel any abnormal
vibration. We program the transmission to get the best possible fuel mileage,
and when we do that the torque converter is locked up in the highest gear
possible for that speed. Sometimes this causes the engine to lug (strain to pull
the truck). When that happens, you get vibration out of the driveline. When you
depress the throttle and give the engine more gas, the transmission will down
shift and the vibration goes away. Also with a stiff frame and suspension, along
with the short wheel base, you feel more road imperfections.

I have concluded this vehicle is performing normally and nothing else needs to
be done."

If you feel there is still a concern present with your vehicle, I would suggest
diagnosis by another GM dealer for a second opinion. In regards to a ride-along
with the service technician, that has to be noted and requested when your
appointment is set, as each dealer is independently owned and operated.

You should demand that you be present for another ride along to show the vibration.

yep, just like the times they reportedly fixed mine they kept saying it wasn't vibrating and when I questioned them they admitted they didn't even drive it on a smooth road at 70mph but instead drove it only on rough surfaced city streets at 35-40mph even though the service ticket said the problem was on smooth highways only and when doing 65-70mph.

 

they test drive it in a fashion or certain way to avoid the problem just so they can deny the problem exists.

 

another thing is if they ride with you the extra weight on the seat makes it vibrate less so they can say its minor

    • When I bought my 14 GMC I turned it off with an handheld programmer. With my 16 Odyssey I left it on solely because I didn’t have much money in the vehicle. There’s a device to turn it off that’s a little more involved. The GMC at 72 MPH the deactivation was on very little the deference was 1/2 mile per gallon. The Odyssey is on over half the time at 72 mph. 
    • Anyone ever thought about switching the interior door panels from the base model to the Denali style? I’ve seen that you basically have to cut, sand, mold, paint, the window switches together to get the look right. Is that the main reason people don’t bother doing the swap? Seems like the only method that is easy I guess, without having to mess around with wiring and stuff.
    • Replace the fuel pump with an OEM AC-Delco.
    • Hello, first time posting here. I have an 03 Chevy 1500HD with the 6 liter gas engine. The truck ran fine until the fuel pump died on me and had to get it towed. Replaced the fuel pump with a precision pump from O’rileys and changed the fuel filter while I was there. The truck will run and drive now but it wants to idle around 500 rpm when in drive and it tries to stall if you touch the gas. It drives fine though, just doesn’t want to idle. Put a fuel pressure gauge on the rail and only have 50 psi. I guess these trucks should have 55-62 psi to run right. I thought the regulator might be the issue because when I would unplug the vacuum hose it jumped to 56 psi. Replaced the regulator and no change. The only thing I can think of is that I was sold a faulty fuel pump. Any help would be appreciated because I’d rather not have to take the bed off again if I don’t have too. Thank you!
    • I've been wrenching on GM trucks for 17 years. And I need to get something off my chest because it's been weighing on me for a long time. After all that time, all those motors, all those people standing in my bay, I've figured out there are really only two kinds of owners. The ones who already know about this. And the ones who are about to find out the hard way. A guy came into my shop a few weeks back in a 2018 Silverado 5.3. Sharp guy, maybe 35. Knew his truck cold. He'd been on the forums, read the threads, done his homework. He only rolled in so I could double-check a little module he'd already plugged in himself. Wanted a second set of eyes on it. Ten minutes, in and out, drove off happy. Two days later, a completely different story walked through the same door. Older fella this time, in a 2016 Sierra. Gorgeous truck, clearly babied, not a scratch on it. Wedding ring. Looked like a guy who took care of his stuff. He was in because his engine had started knocking on the way to work. And by the time I got the valve cover off, I already knew it was too late. Lifter collapsed. Cylinder 5. Camshaft chewed up. The whole top end shot. Same kind of truck. Same motor. Same roads, probably the same dealer. The only thing separating those two men was information. I've been at this since 2008, and I've worked on everything GM puts out. Silverados. Sierras. Tahoes. Yukons. Suburbans. Escalades. The 5.3 and the 6.2. Doesn't matter which badge is on the tailgate. They all carry the same problem. So here's the information one of those guys had and the other one didn't. It's called Active Fuel Management. AFM. GM started building it into their V6s and V8s back in 2007 to squeeze out a little better mileage on the highway. Maybe a mile or two a gallon. All to hit government fuel economy numbers. The way it works, the motor quietly shuts down half its cylinders when you're just cruising along. And the little lifters that pull that off have a tiny pin inside them that's constantly clicking in and out. Lock, unlock, lock, unlock. Hundreds of times a drive. Thousands of times a week. Eventually one of those pins wears through. The lifter drops. And it starts grinding the camshaft down like a chisel on butter. And what nobody tells you is that the shudder you feel around 40 or 50 mph? That's the system cycling. Every single time. Here's what really gets me. The pre-2007 trucks, the ones without AFM, they're bulletproof. I've got customers still daily driving them with 260,000 miles on the odometer. Not a problem in the world. GM took a perfectly good motor that would have lasted a lifetime and bolted this system onto it. And it is wrecking engines that should have run forever. The guys who hang around the forums already know all of this. So do the techs. They handled this years ago. They didn't sit around waiting for the dealership to mail them a warning letter, because that letter is never coming. It's the guys who figured somebody would've told them who end up on my lift. And I want to be clear, because this part matters. Maintenance has nothing to do with it. I've torn down motors with barely 30,000 miles on the clock. I pulled apart a Tahoe last summer with 24,000 on it. Practically a brand new truck. Owner had it less than a year. Spotless oil. Best synthetic money can buy, changed early every time. Made no difference. I've seen guys with full dealer records, every interval stamped. Made no difference. The oil changes were never the problem. The pin was. And no amount of babying that truck stops that pin from cycling every single time you drive. That's the part that eats at me. These are good motors. Take the AFM out of the equation and a 5.3 or a 6.2 will run 300,000 miles and never blink. So a few years ago I started telling every single owner who comes through my doors the exact same thing the smart guys already knew. Get yourself a FullForce disabler. It plugs right into the port under your dash. Couple of seconds and you're done. It just tells the computer to leave every cylinder running, full time. No more cycling. No more beating those lifters back and forth every time you turn the key. It doesn't reprogram anything. Doesn't touch your tune. And unplug it before a dealer visit and there's absolutely zero trace it was ever installed. I've had customers come back at 40,000, 60,000, 80,000 miles after I put one in. Zero issues. The trucks run smoother. And the lifters aren't getting beaten to death every single drive. I won't sit here and tell you it's magic. A lifter that's already damaged is a lifter that's already damaged, and this won't un-ring that bell. But it takes away the one thing causing all that wear in the first place. That's the whole game. You don't need a five-thousand-dollar delete. You don't need an expensive tune. You don't need to tear anything apart. You just need to stop the cycling. I'm not writing this for any company. I'm writing it because I'm tired of watching the guys who didn't know pay four and five figures for it. I'm tired of being the guy who has to break the news. I'm tired of knowing that the guys who did know fixed the whole thing for the price of a tank of gas, and the only difference was that somebody told them first. If you drive a Silverado, Sierra, Tahoe, Yukon, Suburban, or Escalade from 2007 or newer with a V6 or V8, you've got AFM. You've got those lifters, and they're cycling every single time you drive. So be the guy who already knew. Not the one I'm scraping metal out of next month. EDIT: A bunch of folks asked, so here it is. The one I put my faith in is FullForce. This is where to find it: https://www.tryfullforce.com/products/fullforce™-afm-dfm-disabler They back it with a 60-day guarantee too. I've handed out more than I can count and not one's ever come back to me. Not one. See less
