Just got an email from GM, they are finishing up processing the paperwork in the next couple minutes. The close date is being scheduled for 5 Business days from today, so I get the Denali is 7 days.

Jeezuz, this is just like prom night, the anticipation is killing us! Good luck, and I hope the first shaker has not set your vibration sensor to ultra sensitive! lol

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

I can definitely say that I have felt it to a much lesser degree in every 2017 GM truck I have driven, so I can say right now that it won't be as smooth as it should be, but will still way way way better than my 2015.

Hi everyone.

I joined to add my truck to the list exhibiting the Chevy Shake :(

 

I picked up this 2016 Silverado, LTZ Z71 with the 6.2l. Beautiful truck, inside and out, but dang does it vibrate on the interstate! I bought it CPO October 25th with 9200miles on the odometer. After the first trip out of town I couldn't believe how bad the ride was. I felt really bad for my kid in the back seat being shaken up for 3 hours each way.

So I brought it to the dealer and they told me even though the tires road force balanced to less than 12lbs each, one of the tires actually looked out-of-round and they replaced it. The new tire road force balanced to less than 4lbs.

Fast forward two weeks and I'm back on the highway, bouncing *almost* all the way up north. I have video that I've shown the service advisor and he seemed to admit some of these trucks exhibit this problem. They're getting it back tonight before I fly out for the remainder of the week. I'm hopeful (but also doubtful) that the issue will be resolved this visit.

General description of the symptoms on my truck: Minor and inconsistent vibrations from about 45mph - 65mph. Sometimes it is noticeable, other times I can pretty much convince myself it is road conditions.

Major vibrations 70mph+ to about 82mph. Oddly the vibration is worse BY FAR on smooth, new concrete. Old patches of road with expansion joints/defects/etc seem to tame the vibration considerably, though I can of course still feel the road problems.

 

I'm coming out of a Porsche Cayenne Turbo due to it's frequent need for dealer visits. Man would this be ironic if the Silverado has to keep visiting the dealer too.

 

Anyhow, I'm glad this thread exists at least for my own sanity. Can't make this stuff up.

Crazy! Those are my issues exactly! Vibration between 70-82 and it's worse on smooth roads. I'm taking my truck in to a driveline shop this Saturday. They are a very respectable shop. I'll see what they say. Hopefully it's just a bad driveshaft. Keep me posted on what they tell you. 3 dealerships ive gone to. They were all useless. Edited by EspoMan

What was the history of the truck? If you haven't done so already, ask the dealer for a warranty history report. I'd bet you'll find a bit of information regarding the previous owner's attempts to fix the problem.

Just curious but what kind of issues did you have with your Porsche?

Good suggestion. When we came across what looked like a fantastic deal, I was trying to figure in my head why someone would trade a truck like this after only a few months and 9k miles. I decided it must have been grandpa's new truck and he could no longer drive, or perhaps a repo. I guess I have a pretty good idea now, but a history report is a great idea. This truck is replacing the duties of my crappy (but trusty) old '93 sierra for utility, and the Cayenne for family trips & DD.

In my mind, these symptoms do not fit a tire/wheel out of balance issue. I've had that. A wheel out of balance doesn't come and go depending on road surface, nor does it change in intensity like this. It is most similar to when my Porsche had the driveshaft center support bearing bushing torn/beginning stages of failing. Match-mounting and road-force balancing tires/wheels minimized the effect on that car too but replacing the center support bearing was the magic bullet. Please do share your results. I'll do the same, but it'll be early December before I'll have the need to be driving out of town again.

Off topic, but it is an 04 with 180k miles. It has had EVERY documented issue known to the rennlist and renntech forums (several more than once.) I've been fixing them all as they happen, but decided I'm in a position to enjoy a new truck that won't need to visit the shop all the time. Ha!

Let us know what the driveline shop says. Mine is going in to the dealer in morning for load balancing. I seriously doubt this will improve the vibration issue.

Yeah no problem. I will definitely keep you guys posted. I am hopeful, since mine is not AS bad as some people here. I'm gonna tackle the steering wheel vibration next. It's minor but drives me nuts.

I tightened down then loosened the transmission mounts, 60 to 15 to 32 foot pounds.

Drove around for a few days with 60 foot pounds, although stiffer - horrible as you felt it all

Vibration from the rear was felt a lot more.

 

Back down to 32 foot pounds and the vibes are less.

 

 

 

 

Has anyone replaced the transmission mounts.

Ladies and Gentlemen,

 

After 35 years of GM vehicle ownership, I recently traded in my 2014 Bouncing Betty (yes she had the vibration / bouncing issue at 70 and a ticking noise with less than 24 thousand miles) and purchased a New Nissan Titan XD. Yesterday I was driving in Michigan, where the speed limit seems to be 85, when all of a sudden I realized that I was doing 85 and there was no vibration or bouncing. WE need to file a class action lawsuit! I really want this fixed, I want to be a GM owner again. My Nissan has done nothing wrong - No issues at all - but I still crave the Chevy look when I drive by. GM knows what the problem is - WE need to force them to fix this issue! It is time for a class action lawsuit.

Jesse tried to get numerous Lawyers to take a class action. They all declined, they're not interested unless the problem has killed someone.

Which, of course, is ridiculous because there have been plenty of class action lawsuits for silly things that didn't kill anyone like extra fees being charged on cell phone bills or improper medical insurance billing.

I figure it again is just not widespread enough for there to be any money in it. A lawyer won't take a case if there isn't enough money.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.

      About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.

      Bridgestone vs Goodyear tires?

      By Vu1can · Posted

      Maybe I was just too unlucky, but I had nothing but bad luck with Bridgestones. Out of 3 sets, they all started losing a lot of air when they got down to about 1/2 tread life, and at that point also wet traction suffered more than it should have. Also, the only tire I ever had in my 60 years of driving that had a side wall blow out was a Bridgestone.   I'm currently running Goodyear Wrangler Workhorse AT and am very happy with them.
