  1. Hey guys, I posted in the giant thread about my fix but I'm sure it's already gotten lost. I think this is important to at least have floating somewhere for someone to search. Symptoms: At 60-70mph I was experiencing a severe shake/vibration. I could usually push out of it at 70+ but it was still noticeable. It was like clock work as soon as I hit up around 60mph. Solution: I got my truck fully inspected before purchase and they noted the vibration. Mechanic showed me a dent in the drive shaft and general wear on the shaft. His recommendation was to replace it. I ordered the part online. The new shaft came fully assembled with new Ujoints and the yoke to slide in. Installation was very easy. I have driven 100 miles since installation and I have ZERO vibration. I hit 60mph and it is very smooth. So the culprit could be the shaft the ujoint or the yoke. Once again this fix worked for me and it may not be the same issue on your truck but I had pretty bad vibrations and they are GONE. Good luck!! *NOTE* I have no warranty so that is why I attempted a fix on my own. I'm sure this problem will still crop up as peoples warranty starts to expire.
  2. I know this is going to look suspicious being only my third post but I wasn't sure what forum to join at first. I have noticed a shake or vibration in my new 4x4 crew 5.5 box 5.3 truck it seems to come and go and has been a pain to pin point what makes it happen. I can feel it in the steering wheel, seat and sometimes the gas petal but mostly in the steering wheel. It seems to be most noticeable going up or down hill with very light acceleration but can do it on level ground at cruise speed too. And the fun part is it doesn't always do it to make it more of a challenge to diagnose it. Brought it to the dealer last week and I thought the mechanic was going to think I was crazy but he did feel it too which was a relief also the service writer test drove it after they balanced and rotated the tires and he said its slight, but he felt it too. We scheduled it to come in tomorrow and are opening a warranty claim. I have very little faith that its going to get fixed because of the nature of the vibration and it being so new that there probably isn't any info out there on what it could be. I really don't know what they can do tomorrow other then make phone calls. If I had to venture a guess I'm going to say its in the transmission or possibly the engine. We also have a 2012 equinox and on the same roads there's no vibration at all. Also I have the z71 and man does that thing ride STIFF! Every repair strip in the tar is felt hard! Anyone know if it just takes some miles to get the shocks broke in (2600 on it now)? My 04 was a z71 too and rode much, much softer then this. I would really like to get this figured out because it, along with a few other smaller things is preventing me from loving this truck.
  3. I am a proud owner of a GMC Yukon 2016 Denali. Since these cars are not officially available in Europe, I imported a Yukon. Basically, I am very satisfied with the vehicle. But unfortunately, I have a problem with the vehicle, and nobody could help me so far: The car vibrates quite heavily and uncomfortably. The vibrations started when I stopped at the side of the road to let my wife get out. The engine lamp flashed, and the vehicle had hardly any power left. I drove about 1/4 mile, stopped again, and switched off the car. Afterward, I waited for over one minute and then restarted the car. The engine light stayed off, and so I was able to drive on. Also, the power was as usual again. But from there on I had vibrations which I didn't have before. So I went to a service station to read out any errors and get some help. But there were no errors detected. Since the vibrations did not disappear on the next miles, I went to the dealer again. They reprogrammed the ECU unit with the latest software and balanced the tires. Nothing has changed. So I went to another dealer, hoping that it could help me in a better way. They told me that my tires were worn out and that they could cause the vibrations. We changed all four tires. The handling was a bit better afterward, but the vibrations remained. Because in my country there are just about 10 GMC Yukon and a few Escalades driving around, no dealer has a clue and can solve my problem. Therefore I did a lot of research on the internet and on the paid platform of GM (ACDelco TDS) - unfortunately without success so far. I am also familiar with the service bulletins for the 8-speed automatic transmission. But I can exclude these vibrations so far. I have some of these vibrations in my car. However, I have now imported the right oil from Texas by ship, and I will do the oil change within the next days. But the other vibrations are noticeable at any speed, even at only 1 or 2 mph or over 100 mph. Especially when I ride uphill or downhill, it vibrates a lot. As if I had no suspension in the back and the vehicle would bounce around. The vibrations are mainly felt in the seat. Very slightly also in the steering wheel. From the beginning, my car tends to steer slightly to the left. But I never paid much attention to this, because measuring the track showed that everything is ok. I am aware that a remote diagnosis is challenging. But perhaps you have any ideas where I should proceed with my further diagnosis? Is the suspension the right start, the drive shaft, or the wheel mounting? Or could it be the engine mounting? Or something completely different? What is the best way to proceed?
  4. Hi everyone, new to the forum but I’m at the end of my ropes here this is my Hail Mary. So I have a 2016 Silverado crew cab 6.5’ bed 5.3l 4WD 6 speed automatic transmission. The transmission was fully rebuilt at 75,000 The truck has 89,000 miles on it. I am complaining about a shake/vibration of course but I don’t feel as if mine is like most. Mine doesn’t seem as violent as others describe. I’m experiencing a vibration and a noise almost like driving over rumble strip in the road. This problem comes about when you are gentle on the throttle and at a lower rpm around 1200-1500. If you feather the throttle at 55 MPH you can easily replicate the issue. Next is issue number 2 I’m not sure if they are related but my gut is telling me they are, I recently noticed when stopped then slowly take off as in just letting the truck roll at idle of the line I feel like a small wobble/bounce as it kind of rocks you back and forth in your seat. Both issues go away once you give it more throttle. I’ve had the torque converter replaced first once the issue came back I then I’ve changed the transmission fluid to the updated fluid, rotated the driveshaft 180 degrees and that has been the longest fix for 3 weeks. Any suggestions are helpful and appreciated and thanks in advance
  5. Mysterious, Unfixable ‘Chevy Shake’ Affecting Pickup Trucks Too is the title of an email from AutoGuide .com I received today. http://www.autoguide.com/auto-news/2016/03/the-mysterious-chevy-shake-is-affecting-pickup-trucks-now-too.html?utm_content=title8&utm_medium=email&utm_campaign=autoguide_now_may15&utm_source=newag20160331&utm_term=AutoGuide%20Now%20Subscribers
  6. First off, I did a search and the only thread that appeared was the 41 page "Shake or Vibration" thread. But after looking through about half of it, nobody appeared to have a problem similar to what I'm observing. Since I've taken delivery of my Denali in December, I've been noticing a slight vibration in the floorboard when accelerating, and then at certain RPMs. I've had tire and balancing issues before on other vehicles, and this is definitely not related to the tires or even speed - my truck rides smooth as glass. My problem is related to engine RPMs and slight vibrations and is only noticed at my floorboard. The vibrations aren't too bad, but the issue is that my feet (mostly left and right heel) start going numb on moderate to long length drives. When I was younger I had a job as a bike assembler using power tools all day and I would experience the same numbness/tingling in my hands after a long day of building bikes. When the vibration occurs, I can generally let off the gas a little and it'll go away. But it's present much of the time. It's so slight that I didn't really care, but now that it's causing my feet to go numb, I can't ignore it. Has anybody else noticed something similar? It feels like maybe a motor/transmission or body mount is bad. I'm going to mention it the next time I'm in for service, but wanted to see if anybody else was experiencing something similar. Thanks.
  7. This truck is my first 4WD/4x4. So a few weeks ago, I put my truck in 4HI, to drive in the snow, no issues. Put it back into 2WD, when I got home, and haven't needed it since, until this afternoon. When I put it in 4HI, it was grind/vibration central, but when I put it back in 4AUTO or 2WD, there is no issues.
  8. Hi All, Realize there are a lot of threads on this but nothing recent that I can find and nothing on a 2019 model. I have a 2019 Tahoe LT, purchased 08/18, that was a great truck until now. I took it to dealer in 09/19 for oil change/tire rotation at 6,200 miles and felt a vibration upon leaving. I was surprised they could change oil, rotate and balance 4 tires and do a multipoint inspection in 45 min. I thought ok, their balance machine is not right. Vibration turned violent within ~500 miles so I took it to a Firestone tire shop. 2 of the 4 were way out of balance and 2 others were out of balance but to a lesser extent. Did NOT solve shake. Took back to dealer 10/19 at 7,500 miles and complained of shake. They did road force balance and replaced 2 tires. Ran okay for ~700 miles then was back with a vengeance. Returned to dealer 11/19 8,500 miles with same complaint. Ended up doing road force balance again and 2 more new tires. Thing shook as a drove away. Truck is at the dealer now and I'm dealing with service director who claims per the picoscopre, everything is fine and within spec. Running fine. I'm going for a test drive with him tomorrow morning. Has anyone had this issue on a '19? Has anyone had any success getting this issue solved? I don't think I could even trade this thing in the way it shakes right now nor do I want to take a bath on it financially. Has anyone gotten an aftermarket driveshaft? That seems to be a possible culprit although my dealer says mine is fine. New shocks? I'm at a total loss...
  9. Hello, I was thinking of purchasing a 2016 Yukon Denali, but after reading a few forums on here it seems like there have been a few issues with the 2015 model ( buffering noise and vibration). Have these problems been sorted out by GM in the 2016 model? If not is the problem big enough to avoid purchasing a Yukon Denali? Thanks
  10. Just the other day I started to notice a vibration/rattle noise coming from the front passenger side around 70mph. It almost sounds like the windshield, or what you would expect something rattling against glass to sound like. I can’t pinpoint where it’s coming from, but’s somewhere within the vicinity of the passenger side dash/windshield/headliner area. Sounds more like it’s around the headliner area. It it mostly only seems to happen at higher speeds (70+mph) although today I did just today hear it at 60mph for the first time. My guess is maybe the the windshield is leaking some air since it happens at higher speeds??? Because going over bumps doesn’t seem to have any negative or positive impact on the noise. Anyone else have any issue like this, or any guess as to what it might be?
  11. Well I ordered all the parts this morning to do the rear axle shafts and brake job. Truck has 81,XXX miles on it. Factory pads are about gone. The passenger side axle shaft seal is back to leaking pretty bad. It was R&R'd at 16k and has been sweating ever since and the dealer didn't want to hear it. 9 months later when I bought our new Enclave, I made sure I didn't step foot in that dealer. Anyway, I've also had the driveshaft balanced by a local shop which helped out quite a bit. All but one person who I've found did Yukon shafts said it fixed the vibration. So for $260, worth the old college try. Parts list en route are.... -Yukon Axle Shafts -ACDelco Wheel bearings (both sides) -ACDelco axle shaft seals (both sides) -GM Diff cover gasket (yes I know its reusable but I've already used it once with my PML Cover and put silicone on it. ) -Raybestos Police package rotors. I read that these are mill balanced to a pretty good spec. Tolerances in general are much tighter. -Raybestos hybrid ceramic truck pads While I have it apart I'm going to do a gear pattern check, R&P backlash check at multiple locations around the ring AND check the pinion pre-load measurement. I read that one of these lemon buy back vibrators was donated to a tech school and upon disassembly the pinion pre-load was zero. Yes, zero. So i'm going through the axle my way.
  12. 2015 GMC Yukon Denali - 32k miles (6.2L + 8spd). I don't normally do highway speed but noticed yesterday that I had a slight pedal vibration when doing so and it only seems to happen at 60+ mph. My daily drive is under 40mph and no vibrations there. I'm assuming its likely a rear rotor since I don't feel it in the steering wheel. I looked back on my records and it appears front brakes were at 7mm a year ago and rear at 4mm. Both in the "green" according to dealer. I'm not sure if its an eyeball check and they just mark good or if they actually measure but it was 10k miles ago and a year so I likely need new pads. All this to say, with this life and mileage is anyone seeing pad life and possibly rotor life exhausted so quickly? This is a heavy vehicle and the 6.2L gets it up to speed quickly and it does seem to take a lot more to stop it(always this way so I don't think its the vacuum recall). If anyone is getting a 4 wheel brake job at the dealer, what has it run you? Mine is running a special for $139 per axle for pads and $189 per axle for rotors but I'm hoping if it is a warped rotor I only need 1 pair. Also noticed this on the front passenger rotor. Is that defined of a groove normal? To the touch it doesn't feel grooved. Tire inflation is normal.
  13. I have a 2012 silverado 1500 crew cab and I am getting vibration when accelerating at highway speeds but it stops when I let off the gas. Any help would be great!
  14. Anyone know what this noise is? It's very intermittent. Seems to do it most often between 40 and 50 MPH cruising with maybe a slight up hill. Never does it on coast or heavy acceleration. Very hard to tell where it's coming from. 20190521_191545_001.mp4 2014 Sierra Denali 1500 Crewcab, 5'8" bed 6.2 Litter 3.42 axle ratio about 118,000 miles
  15. Good morning, So I'm finally going to reach out to my fellow Silverado and Sierra owners. I have been dealing with a harmonic vibration issue with my 2014 Silverado crew cab 5.3 2WD for around 5 months. I have taken my truck into 3 different dealers to only have the driveshaft replaced under the powertrain warranty and it fixed about 40% of my vibration issue. The vibration can be felt in the gas pedal, steering wheel, seat, and it can be heard. It sounds a lot like a phasing boom. The dealer that replaced the driveshaft has said they now believe its my "CHEAP hancook tires" but I can duplicate the vibration with the truck supported on jack stands under the axle housing (not changing the pinion angle) with the wheels removed. Now with the wheels removed the vibration is not as bad but its still the same vibration I'm experiencing. One dealer told me I have a bent axle but I don't have any wobble side to side with the wheel on. the driver side wheel does look like it has a highspot with the wheel installed (you can swap wheels with the same results). the tech that replaced the driveshaft said he checked the axles and the checked out okay... Now I have yet to get a good dry warm day to throw a dial indicator on it myself to check but I wanted to check with yall and see what you think. the next nice day I get I plan on pulling the diff cover and taking a look inside. but any help would be much appreciated. I took it in to see about trading back into a Toyota and they didn't want to give me hardly anything for it and the new TRD Tacoma I drove just seemed so cheap for the $36,xxx they wanted for it. My Silverado has a lot more features plus im a fan of the LS engines so I plan on trying to resolve this issue before I try to trade it again. vibration is felt from 20-70+mph the worst is 55-65mph. running boards have been removed, new trans mount, new complete driveshaft. tires have been rotated and the vibration is still coming from the rear center of the truck. Vibrates in V4 & V8, and in neutral. I also have a case opened with GM on this issue since October 2018 so it's well documented. 2014 Silverado LT 5.3L 6l80e 2WD crew cab. (built in the mexico plant) 87,XXX MILES. Please keep the stupid comments to yourself. I just want to get this issue resolved so I can enjoy this truck.
  16. Just replaced e driver side engine mount. After the install, my idle/park started rough idling specially it has more vibration and noise during Reverse. Any idea what could cause this?
  17. My 2018 Sierra SLT Crew Cab has an annoying buzzing sound, rattle, or vibration when in motion that come from the headliner, overhead console area. When I lightly press up the headliner or plastic molding in this area the noise stops. I only hear it when no radio is on but annoying on a year old truck GMC. It is not the eye glass holder that I can tell. Any ideas? Do you think the warranty should cover silencing this vibration?
  18. I'm new to forum, I have a 2002 Chevy Silverado 2500 Standard Cab 2 door ( Not a HD ) My Center support Bearing for my driveshaft is Bad. I have searched continuously for a video that has the support bearing (SB) in the same location and cant find one. My SB is Not hanging like others but it was located above the frame. Is this correct? My truck has ran fine for years until this went and I was wondering if the SB was supposed to be installed below the frame ( appearing to hang). Thanks for everyone's cosideration and help
  19. Ok so I have a 99 sierra 2500 4x4 6.0. Parked it last night no problems. Get in this morning back out and put in drive . As I pushed the gas and started straightening the steering wheel the front driver side made a loud pop sound. After that accelerating I had a vibration for a while. Stop and take off no pop but vibration. I drove for about 45 mins vibration went away. I put in 4wd low no issues 4wd hi no issues. Any clues?
  20. Hi all, I have been in the vibration forums for a couple months now and have decided to make a new thread dedicated specifically to the Class Action Suit that I have been working with a lawfirm in Boston. Over the course of the last month, the firm has been actively investigating the issues many of us are seeing in our vehicles. Let me be a little more specific, They have hired outside investigators who are working with the top level partners at the firm to actively research, test, and and inspect the trucks, looking into the Vibrations, Radio Reception, and Transmission issues. I have been sending them any and all information that I come across, that is sent to me or posted in the forums that could potentially help them. In the mean time, I am and have been taking names, email addresses, phone numbers, trucks, locations (city & state) and if you have yet to rid yourself of the truck (trade or otherwise), and now what your issue(s) are/ were. It doesn't matter if you have gotten rid of your truck or not, at worst we may only be able to use your case, at best, we may be able to get you some form of compensation (I can not say for sure, that is up to the attorneys to figure out, what extent that this can go) If you would like to be added to the rapidly growing list of people who wish to be contacted please send me a PM with the information mentioned above. (please note: I can not guarantee the attorneys will contact you, however the more people who join the list, the more powerful the case, and the better off we are) Good Luck with your trucks, Jesse D. ------EDIT------ I decided to combine the yes and and about to send information to Jesse D. into one line item. those of you that have sent me your info or those who were in the about to category please resubmit your vote to the correct line. those of you who haven't voted but already sent me your info, please submit your vote, i would like to try to keep this as accurate as possible. I do have some names from people I have talked to who are not on the forum, so I know it will never be 100%. Thank you Jesse D.
  21. 9/15/15 - I took delivery of my 2016 Yukon XL Denali around noon. This truck was DX'd from another dealership approximately 100 miles away and was driven here on Monday (9/14/15). I took a quick test drive and was focused on the buffeting issue. It was definitely there but didn't seem to be as bad as previous vehicles that I had driven. On my way home I noticed some severed vibrations above 70mph all the way up to about 80mph. I called the service department yesterday afternoon and made an appt for this morning. We needed the room that this vehicle provides fairly quickly (lots of travel with soccer, aging parents, etc. - my wife, two young daughters and two puppies less than a year old). Some say why didn't you just swap it out with another one? This configuration was exactly what I wanted and, unlike White Diamond, the Summit White's are hard to locate, especially a 2016. 9/16/15 - took car in and described in detail what i had experienced (the buffeting and the vibration). 3 hrs later they informed me that a GM representative happened to be onsite and that they found 3 of the 4 tires to be significantly out of balance (via road force balancing). They have 20-30 (I don't recall which exact number) tires in stock of the same exact model that's on my Yukon XL (22"). They are having to put a tire on a rim to get them all matched which should solve the vibration problem. I was put into a Chevy Impala from Enterprise (there is world championship bike race in town for the next week so all larger rentals are gone, apparently). EDIT: They called me back and offered up a 2016 Acadia Denali from the dealership. Not a Yukon XL BUT certainly not an Impala. Stay tuned.
  22. Hey guys just bought a 2016 Chevy Tahoe LTZ on November 10 and it has been shaking and vibrating at speed above 67mph. I noticed a lot of vibration driving on the way home the first day,so took it back the very next day. The dealer did balancing and gave it back to me but it still vibrated so took it back the next day again. This time dealer kept it for 2 days and replaced 2 tires which could not be balanced and then gave it to me. The truck still had the vibration so I took it back immediately and asked them to look at it. The mechanic acknowledged that vibration is present and said that it is normal and all of them do this. So I test drove an indentical suv and that did not vibrate. So the dealer kept it another few days and are now changing all the tires again. At this point I think there is something wrong with the suv as it has been in the shop for more days than I have driven it. It has only 500 miles and all are due to service advisors's test rides to check for shake. Dealer has been courteous so far but I don't think they have a clue about what is wrong with it. Any pointers what could be the problem? I am seeing lot of other posts with similar problems on the forums but no resolution so far. Reached out to GM but no replies so far. Very concerned and frustrated with this purchase.
  23. Actual photo of my brand new 2018 Silverado High Country. It's been at the dealer for about 2 weeks now - still has the temporary tag on it. I asked them to look into the vibration in the steering wheel. Haven't seen it since. I think the dealer is doing what they can and trying to fix it. But they don't seem to be getting any support from Chevrolet/GM. Nothing like replacing that new car euphoria with a good swift kick in the balls. #Chevrolemon
  24. anyone else have a problem after lowering there Silverado. After I did a 2x4 drop when I hit 80 mph the driveline starts to vibrate. Anyone find a fix for this.
  25. Hi Everyone, So my truck has been at the dealership two times officially now. This 3rd time I had my friend look over it and he said the truck was within GM's specs. I don't know what GM's specs for vibration are but my vibration is in the mid 70mph range and excessively vibrates and then smooths out. This is a constant cycle throughout my commute. I am going to pull my driveshaft and take it to a shop that specializes in driveshafts. I know several people have had their driveshafts replaced under warranty and it did not correct the issue. My thoughts are if your truck originally came with an out of spec driveshaft chances are there is a whole stockroom somewhere in the Parts Department that has out of spec driveshafts mixed in with the ones without issue, hence the reason some people have no luck with driveshaft replacement. I really feel this could be one of the major issues behind all of this especially when there is documentation instructing the technicians at the dealerships to use hose clamps to balance the driveshaft. I'm sorry but I don't see hose clamps as a permanent correction to this issue. I will update this post when I get the results from the driveshaft inspection. Please feel free to share your thoughts and bounce ideas around. Collectively I believe we can find an aftermarket fix for this issue, it may not 100% resolve the issue but will at least save people from taking huge losses on trade in (if you did not go through a buyback/lemon/customer satisfaction program). (A lot of people are trading in / selling their trucks because of this issue) ***UPDATE 01-22-2016*** I contacted the Team at Precision Shaft Technologies (http://pstds.com/) in Clearwater FL and they were able to squeeze me in as a walk in. (Not there normal protocol. They were super friendly, informative, and VERY helpful!) I drove up there and pulled the driveshaft in their parking lot. They then put the driveshaft on a machine and it was a near perfect balance. They added one small shim to the U joint to get it perfect but I'm sad to say the vibration is still present and there was no change. However, when I returned home I put my truck up on jack stands and ran it up to the speed I had issues at (per GM's service docs) and there was NO vibration. I was extremely confused at this point. I dumbed it down and looked at the rear wheels while the truck was in drive (idle speed) on the jack stands (be sure to block your front wheels and disable traction control / StabiliTrak if you plan on doing this on your own). I noticed my left rear wheel has a slight flat spot it in so much so that it's extremely difficult to notice. I have not had a chance to swap a known acceptable wheel to the rear at this time. When I do I will update this post. A recap for a description of my vibration: -72-74 MPH there is a cyclic vibration. Roughly every 7-8 seconds the truck has a vibration and then the vibration disappears.
