In conversation with my service advisor, he commented some suspicion from GM regarding the aerodynamics in this new body. But when I asked why double cab, crew cab short and crew cab long have the some problem, no answer.. I know that is different, but I had the vibration with and without tonneau cover.

 

Yeah, I still have a vibe with my tonneau cover on as well.

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 don't have a shake or vibration issue (that i don't know off)but yesterday after making a trip to Houston I noticed that when I am accelerating at 85 or more I hear what appears a humming noise coming from the front of the truck. Anybody else is having this issue?

+1 Retard. Go troll somewhere else

 

You are clueless.

 

Seriously? Go back and check when this vibration thread was started. It's been a significant problem for almost a year now. Moron.

 

Enough with the name calling. Get back on topic.

Well, wishfull thinking...it was just the cooler temps and not the tailgfate being down. It was mid 90's when I left my client and the truck was vibrating on the way home with the tail gate down. I still think it had a little bit of an impact, but not a big one at all. Oh well. Back to the drawing board...cuz GM certainly isn't at their's.

The impact it likely had was the drag force created by letting the tailgate down. Basically when it's up a pocket of air forms and travels in a circular motion within the bed allowing air that passes over the front of the truck as you drive to continue to pass over the pocket in the bed. The pocket of air in the bed acts almost like a camper shell. When you let the tailgate down, the pocket of air can't form so air passing over the truck from the front doesn't flow nicely over the bed and instead exerts a downward force on the bed creating drag. This is why letting your tailgate down while driving is worse for fuel economy, not better. Mythbusters did a whole study on this. That downward force or drag likely helped calm the vibration down but was neither the culprit nor the solution for the vibration problem.

I had both factory 18's and 20's. Both sets were equipped with factory Goodyear's. Both had vibrations. Even after multiple road force balances and rotations.

I to have noticed a shake while slowing to stop,then turning right it still shakes slightly as I pull away.it seems like it goes into v4 as I'm stopping (no v4 light on )which at low rpm might shake worse?and stays until I accelerate.

So if it cured it for a few days and came back, it seems that the tires are slipping on the wheels and throwing it off again (stating the obvious here I know). Wonder if the new wheel design has something to do with it.

 

Does anybody have this issue with aftermarket wheels?

They rebalanced my factory 20s with the Goodyear ls2's, twice, still shakes. I then put on my aftermarket 20s with toyo open country at2s(rode smooth on my 12 sierra).. Didn't help the shaking that's still there.

Anyone with non-Z71 (stiffer suspension) has the vibration issue?

I tested some z71 and non-z71 and looks like the non-z71 absorb (hide) the problem better.

I dont doubt that...I have a Z71 and run my tire pressure so they never exceed 33 when warm...today was in the 90's and they expanded out to 34...one was at 35. It helps a it for sure.

The temps here today were in the low 90's...very bad shaking at highway speed. Has anyone else noticed this? In the am on the way to work it's not too bad....but once it warms up wow...completely unacceptable ride. I'm not kidding here...looking forward to the fall and a better riding truck. Mine seems to really run poorly in this heat...runs poor, seems sluggish, MPG went down a bit, and shakes worse. Whats up with these trucks?

Yeah lots of people with non Z's having vibration issues if you read back through the entire thread which takes a while to do. Edited by Silverado-Hareek

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
