Everyone should take videos of their vibration issues and post them on YouTube.

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

So I dropped my truck off last night at the dealership. The service manager calls me and leaves a voicemail at 7:30 tonight and says the GM Engineer had been working on it all day and it is fixed. Im not very optimistic but I'll report back tomorrow.

This should be interesting.

Please this sounds like the most pratical fix to date, and we do have 1 confirmed fix with the c clamps to driveshaft as of yet.

We should be demanding our dealership to have our driveshafts balanced independently first, before any other action!!!!!!

This will prove that the driveshaft is indeed out of spec right from the factory, and any replacing of the driveshafts through warranty must be confirmed by factory tested and confirmed parts.

 

Machine welded driveshafts, means thousands of out of spec driveshafts, and absolutely no qualified quality control being done at the manufacturing level.

This my friend is what upsets me the most! A good truck, with cheap parts, and untrained associates, and a failed quality control system will destroy GM's legacy wait and see.

I hope some big wig at GM is reading this and wakes up with swift changes!

 

I got a quote from a local driveline shop for $60 to balance the shaft if I bring it to them, or $100 if they have to pull it themselves. So its a cheap fix if this winds up solving it, instead of letting GM throw new driveshafts at the truck when the new ones in fact could be out of balance as well.

 

The hose clamp method is BS and especially for GM to recommend that. It is just going to mitigate the problem, not solve it. They just put the truck on a lift, run it up to the speed of the vibration and see if its better and then tap the hose clamp around and keep trying until the vibration seems better. It needs to be put on a balancer and given the exact amount of weight required to balance it out, rather than whatever the weight is of one or two hose clamps. One could not be enough, and 2 might be too much, have to have a balancer do the job and get the perfect amount.

 

I believe 20Bowtie14 said he was going to go to a driveline shop. Hopefully this is the fix and we can all move on. I would volunteer my truck but I've already been through this once as my last truck was in the shop for 54 days in a total of 5 mos, and I don't want my new truck to be a frankenstein truck like the last one until I know what exactly needs to be fixed instead of throwing parts at it.

Got my popcorn out. waiting to hear Boughtalemon's outcome.

 

I am betting he gets the same results as mine. Two clamps and a phone call from GM telling him they are closing the case because his truck is now in spec.

 

Of course there is the off chance his problem is something else. Something that may take baling wire and duct tape to fix.

 

 

Side Note: I called the professional balance shops in town. It is less than $100 to balance the shaft. I may take mine over and just have them check the shaft with the so called fix GM put on.

3.08 on mine and smooooth.

3.08 on mine and not so smooooooth!

 

Multi-part post here:

 

Number one, thinking about contacting GM and suggesting they tweak the Chevy slogan to 'The irregular heartbeat of America.'

 

Secondly: been following this every day, but haven't posted up to now because I thought my vibe was on the minimal end of the spectrum. (And I'm not letting them tinker with it. I'll wait until they release the fix.) I only have about 1,800 miles on it--but now I think it's getting worse and more (if that's possible?) random. Used to be very subtle at 61-70 mph. Today I thought I could really feel it in the steering wheel for awhile; then it disappeared again (so I'll have to pay closer attention in the near future, I guess.)

 

Third, no offense (and I know it's difficult once you get mesmerized), but if you have not purchased a truck--I don't know how you could read all these posts and still consider it. If nothing else, be patient and wait for the '15s! My original plan was to run my old truck into the ground and then maybe getting something like a '65 El Camino and pimping it out. Wish I would have! Would've been so money ahead!

 

Fourth, what are others getting for mileage? I'm not impressed with mine. Computer displaying average over the last 400 miles says slightly less than 15. This is with about half local and half highway miles; taking a 200 mile road trip today--so I'll see if it goes up.

 

Good Luck!

It'll be next week sometime, but I've already called my drive line shop to balance the drive shaft. After the driveshaft was changed in my first 14, the vibration did get better but was the same frequency. I really hope a good balancing is all we need..

No, the results may surprise you. He may end up with three or four clamps. :lol:

Im curious to see what the fix was as well. Just about every part in the driveline of mine has been replaced. It has been 30+ days in the shop so I opened a case with GM Tuesday to get my ducks in a row to fight for a buy back. The same day the GM field engineer told them to lock open the flapper in the exhaust due to it causing vibration in a few other cases.

 

GM contacted the dealership Wednesday about my complaint and the sales manager called me. I told him we were getting into lemon law territory and I was tired of the tinkering on my truck and didnt even want it back at this point. Coincidentally later that day the service manager calls me and says locking the flapper open fixed the issue and they are ordering me a new exhaust system now with a redesigned flapper. Should be in today or tomorrow.

 

I am very skeptical if this fixed it or now they feel a sense of urgency to get my truck out of there before they are forced to buy it back.

Personally I think its definitely a driveline issue and its too much vibration 70+ to be a little flapper... Good luck though! If this solves your problem I'll be one of the first around here with an after market exhaust on my truck lol.

      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.
