I was under my truck this am looking at the flapper exhaust valve and noticed my drive shaft sitting there. It appears marked, and there's what looks like a spot welded on weight on it, and well as the yoke or what ever it is that the shaft slides into before going into the rear end. It appears there was some effort there to balance the shaft and the yoke. I also can now see the ripples in the sidewalls of the tires and you can really feel them when you run your had on them. I think these GY tires are junk and are likely the cause of all my vibration issues. Here's a pic of the shaft and yoke. I also see a "made in Canada" stamp under there...how can we tell where these trucks were made? Can you tel by the VIN? Also, cant really tell but my drive shaft appears to be steel and not aluminum but I'm not really sure on that. My truck was made in Dec 13.

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

The sticker inside your driver door will tell you the build location of your truck. Your drive shaft definitely looks different than mine. Mine is silver, which I guess means it's aluminum. Build date on mine is September 2013 in Mexico. After seeing some of the vibration videos posted here I can say my truck definitely does not exhibit that kind of a heavy vibration. Just a slight vibration/shake in the steering wheel that I think is tire related as well.

Just checked the inside of my door and it says "Fort Wayne Assembled"...so 'm guessing my truck was made in Fort Wayne..Iowa? Like I said, I have the Fort Wayne sticker, and underneath there's a Canda sticker so my tuck is either made here or there. From what I can determine, there are welded on weights so it seems things were balanced and assembled correctly. I'm getting a lot closer to biting the bullet and buying new tires. My gut thinks that's the sorce of a lot of people's problems.

 

I agree...my vibration is nothing like that video that was posted...that's pretty rough!

Yeah I'm back and forth between trying to work with the dealer for new tires or just spending the money on something nice like Michelins that I think will fix the problem. It's just tough to swallow the idea of buying tires on a new vehicle with only 3,500 miles. If I decide to buy tires though I'm going to wait until the winter and then get some all terrains. I figure at least wear these crappy ones out a little longer while the ride is tolerable and save a little money at least.

I took mine in to the dealer to have the tires balanced. It seems to have helped a little but I really think theses OEM tires are very poor quality. Service guy said they would consider swappping the tires out for a set of Michelins but I have to pay the cost difference and mileage for the GY's which now have around 11k. I can straight out buy a set of Michelins for around 1100 They are supposed to call me back in the next couple of days to let me know how much. If it is around 1/2 the cost of a new set I am going to do that I think. The GY's are getting worse as they get mileage on them. I understand this is a truck and maybe should not ride like a Big Ole Cadillac but man why should it beat you up when driving it especially since the sticker was over 50k!!!!!!! 2014 Sierra SLT CC Z71 4x4 20in wheels... Worst thing I have noticed is the GY's seem to flat spot if they sit for a few days they are really rough (feels like a SQUARE tire LOL) for the first 5 to ten miles until they warm up then they get slightly better.

That flat spot feeling is the same reason I changed from Continentals to Michelin. All great now.

I have the Bridgestone duelers LT rated tires on my truck . No issues at all. Seems like a lot of issues with the goodyears ?

Here's an update on my truck.

 

I had the vibration around 35-50 mph, especially during coasting/deceleration.

The dealer originally told me it was due to the AFM switching from V8 to V4 mode.

They also blamed the Bridgestone LT tires that I had replaced the Goodyears with.

 

On the second visit, I explained to them that when the transmission was left in M5 mode, it had the same 35-50mph vibration even though the AFM stayed in V8 mode.

The shop foreman then claimed they couldn't troubleshoot it anymore because of the LT tires.

After some heated discussions, the shop foreman walking away & refusing to work on my truck, and me discussing with the service manager that I wanted to speak to the regional service rep and the dealership manager, they decided they would look at it again.

 

Overall, they had the truck for over two weeks on this second visit and, according to the service report, this is what they did:

Swapped tires with FIVE other trucks.

Swapped prop shaft with another truck.

Found rear end ring & pinion was 0.001" out of spec.

Installed new ring & pinion.

 

I picked up the truck last Tuesday and have put about 500 miles on it since.

The 35-50 mph vibration is gone.

Highway speeds seem to be pretty smooth.

Again, I do have LT tires on it so I do feel the road a bit, but I can't complain about that.

 

Overall, I wasn't happy about the process I had to go through to get this taken care of, but, as of today, I am satisfied that the issue is gone.

Just thought I'd post a success story on here; doesn't seem to be many of them.

What was your trucks build date? Mine was assembled July 2013 in Ft. Wayne, Indiana , and I have similar vibrations (3.08 gears). Perhaps this is where my problem is also. Did they reinstall your original prop shaft?

The 5.0L would have been the better engine choice, but whatever. This makes you number 9 on the "trade my new 2014 gm for the competition list" that I know of. Brutal!

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
