biggspell you make no sense.

Totally agree with the above. So what your telling the forum is that your dealer is the consumate road force tire balancer and if they aren't, you refuse to take it elsewhere to check the balance since it's under warranty.

 

I've heard it all now!

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 think he is saying the dealer should be competent enough to balance a tire.

 

Strangely enough though, it seems they aren't. Last time I had tire issues I brought it to the dealer to fix (had a slow leak) and they never repaired it. Just kept telling me there was no leaks by doing a dunk test. Brought it somewhere else to have the tire remounted and sealed, never leaked again.

Believe it or not I have a great dealer whose service manager / department, owner are second to none. They are working with me to get this issue resolved and at the same time we are building a case. I'm not going anywhere else and drop additional coin at this point. I'm not posting here to argue with anyone I have better things to do. By the way, the service manager informed me that the GM Technical guy has been hearing of these issues and a bulletin should be coming out shortly. The Tech. said they have been replacing the drive shafts for the cure. The service manager has ordered one including the yoke and this will be overnighted to him. Hope this works..

Made an appointment with service today, They said it is normal to do this. Something to do with the active fuel management on the v8. But I have a v6 in base model when I told him this he was kind of dumbfounded as he didn't think my truck had the cylinder deactivation. We will see what they have to say when I bring it in thursday

Update: The truck is back at the dealer as of this morning, i'm still chasing the vibration issue. I was told they are putting on a vibration analyzer to see what is vibrating at speeds above 70mph. I was also told by the service manager that there was a case at another dealership in south jersey where switching to Michelins cured the high speed vibrations on a 2014. I currently have the oem Goodyear LS-2's on the oem 20" wheels, the truck now has 2900 miles on the clock. I also asked the dealer to look into the high pitched squeel coming from the 4wd switch when the truck is put into auto or 4wd. I will report back with updates as always once I get the truck back. After reading this forum, does it seem that most with vibration issues live in the Northeast?

Tell them you want them to swap out to the Michelin's strait up. Regardless of whether it's the tires or not the Goodyear's are junk

Im not going to get too excited about the tire swap yet, but it seems that the dealer has found the same thing that I found in regard to the actual RPM where this truck is vibrating. I didn't have time to type all this earlier in my previous update...

 

I used to work for a major yacht builder that used meters for vibration analysis so I got to thinking... A quick internet search and I found an Iphone App called "vibration". The app did cost me $4.99 but at this point I think its worth it. I started the app, ran the truck to 75MPH and took a 40 second reading while holding the speed constant at 75MPH with cruise control. (I did this prior to taking the truck into the dealer today.) The app will output in HZ or RPM whichever you choose. I found the highest spike at around 800 RPM at 75 MPH as you can see in the photo. There are (2) other high spikes in the photo, (1) around 1600 RPM (Engine) another around 2400 RPM (Driveshaft) After some quick math I determined that the 800 RPM vibration is wheel / tire / axle speed related and the most pronounced.

 

I was skeptical at first, however after using this app, I found out that it is actually VERY sensitive to even the smallest vibration. And no, this isn't an infommercial for the vibration app. It is just something that I found, used and passed along in hopes of helping others in the group as I know first hand how frustrating this issue is...I am supposed to pick up the truck tomorrow with the michelins...we shall see if its fixed...if anyone does download the app and can't figure it out pm me...its more intimidating than it looks....my only advice would be to take the longest data reading of 40 seconds as its easier on the eyes to read. Also hold your speed at a constant once you get your vehicle up to the speed where the vibration is felt, then start your data recording...

 

If nothing else this bit of information may be able to point you in the right direction...

Svtkidd...by the looks of that graph you were taking a measurement while getting the truck up to 65mph. The key for vibration analysis is to hold a constant speed and then take the reading. I see on the graph you have a lot going on in the 3500-5000 rpm range...someone correct me if i'm wrong but the only thing on the truck spinning that fast would be the motor...unless u were doing somewhere around 160 mph then maybe a driveshaft...

      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.

      Towing In Loose Gravel

      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.
