I picked up my 2014 Sierra All Terrain last night and so far everything has been great. I test drove it the day before to give the dealership the ok to spray the bed liner and during the test drive I noticed a vibration mostly through the steering wheel, like some have described. I told the dealer and they had the service department look at it before I picked it up last night. They force road balanced the tires and the vibration is gone, drives beautifully. My vibration came on around 75 and persisted through 80+. Was very slight under 75. Only have 120 miles on it so if anything changes I'll let you guys know.

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 today I just pulled my 600# snowmobile on a 2 place aluminum snowmobile trailer and had the worst vibrations I've experience so far. This has me more convinced my vibration issue is related to drive shaft angle. The weight on the back of the truck is slightly lifting the front and in any other truck this isn't an issue but since my truck has a vibration unloaded the extra drive shaft angle makes it worse. How does a guy get a proper drive shaft angle?

That is my exact problem too. Not sure if you saw my post towards the top of this thread but I actually rotated my tires on my trailer in a Walmart parking lot because the vibration was so bad with a similar trailer. I am confident that this is a prop shaft issue and GM knows it. It will just be a matter of time before a recall goes out. Edited by Szyikowski

So has anyone really determined whether its tires, axles, driveshatfs, or whole rear ends? I guess I'll start with tires. I have a very slight but noticalbe vibration at ALL speeds. I've called the dealer who said to bring it in but I haven"t had time yet.

I actually was trying to get video of how bad my had would shake on the wheel when pulling the trailer. I think if I added my buddy's snowmobile on the trailer it wouldn't be drivable. I think today I'm going to put my ATV in the box (650#) and take it for a drive just to rule out the trailer, although I've never had a problem with the trailer before. If it vibrates bad I will bring it to the dealer with it in the back on Tuesday when they fix my seat.

Just got done with taking for a ride with my ATV in the back. It drove the same as it does empty, so it the weight might not be far enough back to have the same effect as having all the weight on the receiver hitch.

Silver Spaceship, you ever have your tires road force balanced? If they are off extra load would definitely make it worse. I know people have been saying the pinion angle could be off but I don't see how that would cause a vibration unless the spring blocks in the rear suspension had different angles cut in them or if one didn't seat on the rear end properly. I have experienced vibrations above 50 in a different car when the u-joint wasn't bolted to the rear end properly, kid who bolted it up didn't notice that one side was sitting on the alignment tab.

As others have mentioned could be a out of balance drive shaft. Could also be a defective u-joint somewhere on the drive line. With all the tire related issues I've seen posted I would lean that way though, and as I mentioned in an earlier post my vibration which came on about 70, went away once the dealer road force balanced the tires. I also towed my 6k lb boat yesterday and no vibrations at all, pulled like a bull.

Well I went and got on the interstate this morning after reading this to check mine at the higher speeds and guess what?When it reached 82 mph the vibration started and was terrible!!Drives so smooth at speeds below 80 with zero vibration!

Well scheduled my 3 rd trip to dealer for THE SHAKE that everyone unfortunate buyer is experiencing. So far they have replaced all 4 tires and road force balanced them and vibration/shake is still there at speeds above 65.

The dealers can't fix an engineering problem. This must be addressed from GM's engineers. I'm going to lemon law it if they can't address this miserable issue.

It is the tires. I had vibs over 70 mph and was corrected by tire trueing and balance on the truck. If such is not available to your area, recommend you find a shop or discount tire that knows how to properly road force balance a tire. If it takes too much weight, have them rotate the tire 180 on the wheel. Or just stay below..80..if you are kidding about this

      Some Assembly is Required

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
