This confirms something for me, my suspicion has been that these truck resonate at 39 Hz which means even slight disturbances can cause vibration issues. Which for tire speed peaks at about 75 mph.

I drive a 2016 Silverado LTZ 4wd   I recently fixed my vibration issue, I found it was a faulty Torque Converter... It shuttered and shook at different speeds but not constant. GM warranty replaced

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 6

Seems plausible but it also seems like a sales pitch for a $399.99 app for your cell phone. I’m skeptical ? 

Asking my mechanic about it.

I noticed when I put the transfer case in auto the vibes are greatly reduced.

Anyone tried this?

Yeah, I wouldn't trust that app to diagnose the shake on these trucks. I have an EVA that shows my shake as being a first order tire vibration. Problem with that is the same vibration exists and I've ran three different sets of wheels/tires, two sets of axles and replaced a 4 rotors on a vehicle with less than 20k miles put on it in over three years.

 

Would cost less to buy a used EVA or pay the dealer to run the pico to get you the vibration frequency and then try and track it down from there. But there are still no guarantees.

Just as a heads up to this Soga 

I went to dealership to get an oil change and a tire rotation.  I’m at 56,000 miles and when I drove off I got on freeway and a shake that y’all are talking about was present.  I let the service writer know right away.  He stated maybe the tires need to be balanced.  3 shops and a brand new set of tires later still have a shake.  So then I’m really confused so take to a shop that has really good reviews and I’m explaining my story and he tells me let’s try and figure this out.  I said ok.  After about 30-40 mins he comes back with a caliper type thing on the drive shaft and shows this drive shaft is egg shaped now.  

 

Not or sure if it was a coincidence or just happened but to not have this issue and then find my drive shaft is bent I am pretty proplexed and will be talking with dealership on Monday.  Will report back if this fixes the issue.

Which for tire speed peaks at about 75 mph. or 3 times the rotational speed of the tire. Because the rear end ratio is 3.42 in your truck the drive line angular velocity is approximately 39Hz at 65 mph. Confirms the problem is resonance and the body mounts like to transmit vibrations in the 39 hz region. Like you said the dent looked so minor you wouldn't think it would cause issues but if you have a resonance situation even something minor makes it way through. Thanks for the info

But would this still occur at lower speeds?  Mine shimmies at 20-25mph and again 45-49mph.  My 2014 Silverado has been in 3x now. Replaced the torque converter and not fixed.  Today the service dept said they had 3 other Silverados in with same problem and none of them exhibited the vibration/shimmy including mine.   At this point I am not happy that this problem continues to be undiagnosed.

Has anyone on here had more “mild” vibrations at 70 and it worsen at 80+? Mine isn’t bad at any other speed Really. Pretty much 75 to 85 is the worst. I’m trying to weed out the “all speed ranges” vibration guys and the 70-80 guys that have fixed their issues.

I own a 2018 gmc sierra 1500 6.2 that I purchased new. All was going well until at approximately 23,000 miles the truck started vibrating. It is noticeable at speeds over 35mph. The sensation is like driving over rumble strips. The steering wheel shakes quite a bit. This is not constant. It comes and goes.  The dealership told me the cause was 2 front wheels that had dents. They balanced all 4 wheels and put the dented wheels on the back. That did nothing. I am now reading that it could be the transmission. I hope this is not going to be a fight with the dealership. I hope to get this squared away before the warranty expires. UGH

2018 w/ 8 spd?   if so trans could likely be issue.

 

as could the torque converter.   dealer should know the TSBs for them

Was the new drive shaft aluminum or steel ? And was a regular drive shaft or a 2 piece? I’m having the exact same symptoms.

Symptoms: At 60-70mph I was experiencing a severe shake/vibration. I could usually push 

Was your replacement driveshaft steel or aluminum?

I recently fixed my vibration issue, I found it was a faulty Torque Converter... It shuttered and shook at different speeds but not constant. GM warranty replaced TC and balanced tires and all Vibration was gone... I now love my LTZ....

 

PLEASE for those feeling my frustration check this out. I was about to use the OHIO lemon law to dump this truck but now all is right in the world again. If you need to PM me and I will scan and send the GM repair order.

 

Also IF your a internet surfer please spread this word as I am not going to, but felt it my responsibility as a Chevy Truck guy to post this.

Any chance that you might still have that GM Repair Order that you had mentioned in this post from way back when?

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
