The only thing that shakes on my 5.3L / 8spd RST Z71 after 5200 miles is the ground when I cold start it. 


VRRRRROOOOM!

As listed on the Maroney sticker '19 RST came with a dealer installed option 22" low profiles separate from the factory steel wheels. First 1K, some rear wheel hop and 62-67 mph vibration, not a shake

Crap shoot.

Good luck.

I would also stay away from rims over 18 inches.

Great truck. 

Mine too after the road force balance. Must be the exhaust damper that roars on start......put a 2-3/4 to 4' extension tip on the tailpipe and it roars louder!

got my truck on Wednesday last week. Driving around town, no vibration issues but whenever going between 60-70 mph on the highway, feels like a speed strip. No sounds or anything but vibrates like a speed strip. Dealer has the truck as of yesterday and they are supposed to be putting new tires on. They think there's a hard spot on the tires. (they already re-balanced and road force balance). Not necessarily the classic shake of the silverado but just posting this in case anyone else has this issue

Had the same problem with mine... After a tire rotate and rebalance didn't work the dealer found what the issue really was.  The driveshaft had a dent!  They replaced the driveshaft at no cost since the damage came from the factory.  Hope you can find your gremlin!

Fingers crossed! I'll bring that up to them when I go for the ride along Wednesday :)

2019 Sierra SLT.  I have the vibration / resonance occurring randomly from the back 1/2 of the truck at about 65mph and 1400 rpm while going up a slight incline in 2WD.  I have the same vibration when I slowly backup up a slight incline (driveway).  The vibration will go away if given less throttle or more.  After looking underneath the truck, I suspect it is one of the two stamped metal heat shields near muffler / fuel tank.  I will be taking it in to dealership soon to demonstrate what I can do to repeat the resonance.  The vibration sound is not related to the truck performance, because this truck rides perfectly otherwise.

mine has smooth as silk....been waiting to do anything because it rides so good, cept for body roll...

 

I did have Toyota that had shake at 60mph and never got remedied.....tried everything even new rear axles, it did have bigger rims and tires so.....

PROBLEM SOLVED - The resonance / vibration sounds comes from two metal shields located between the exhaust pipes and spare tire.  In certain road and speed circumstances, they vibrate (similarly to what a tuning fork does).  GMC has not come up with a solution yet, but will reply back here when a solution is provided.

2019 Denali Ultimate with 22" wheels 600 miles is a shaker. Had in today and they road forced all the tires and it is improved but still shakes. One tire (RR) could not be brought into road force spec.  They wanted me to drive it a few days but I can already tell it is going to be a problem. Hoping they will order me a replacement tire when I call them next week. (fat chance of it magically getting better on its own LOL)

Any info would be helpful .  Bought this new 2020 3.0 liter duramax to replace my tundra vibration at 65-plus .  I do have 18” wheels with falken wild peaks on it but it has had a shake that felt like unbalanced tires even with the stock tires.  I have had to the dealership several times they have visually inspected and don’t see a problem just paid them to road balance with little change.  They put it in some test deal “pico” and that’s where they determined it was balance issue .  I just drove back home 100 miles and nearly same vibration especially while going up slight incline .  Not sure where to look for answers.  They did say they didn’t see any dents or weights missing on driveline .  I’m lost but not super excited about spending that much money for a crappy vibrating ride ..

i have a 2020 silverado , since new and i only have 3800 miles on it now, it has had this intermitting vibration , it happens between 58 and 64 mph, feels like your driving on the rumble strip , mostly does it in 6th gear, looks like i`m not the first one to notice this .

My wifes 18’ Sierra Denali had the shake and rumble at 300 miles when new. I researched the Tech service bulletins and found one regarding Trans fluid. We took back to dealer they did the flush and fill procedure and truck has been great since the flush and re-fill.

Turns out they got a bad batch of trans fluid.. I was skeptical but it actually fixed it.

Don’t wait get it flushed before the trans grenades.

There is a tech service bulletin on this.. get the trans fluid flush / fill procedure done.

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

      Parking Brake - Automatic Engagement Questions

      By SoCal Angler · Posted

      2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.
