In my case it made my problem significantly worse. Now I am getting passenger seat vibration as well as steering wheel / center console vibration. I suspect they were not done properly or the machine was not calibrated or operated in manual mode. I will get specific numbers when visiting the dealer again.

 

Another thing to note. I'm curious if locking lug nuts could cause a balance issue. I have not weighed them comparatively to the standard ones but I've read these can be up to 1.5oz and that often adding a counter balance to the inside of the rim may counteract it.

 

Since the tires are put on a machine without the lug nuts I could see how this would feasibly throw things slightly off however i may be way offbase or perceiving this would need to be done at high speeds.

 

I noticed that the right side tires have weights both on the inside and outside of the rim while the left tires only have them on the outside of the rims.

 

Can anyone with experience confirm if this could cause an issue?

 

 

Also found the following from another forum post. A good bulletin explaining the troubleshooting tips for vibration issues.

I have the locking lug nuts on my 15 and don't have this issue. From following this form I suspect the axle shafts or something near them are out of alignment. Not once have I seen anyone say they have been inspected;

 

There are three types of major vibrations:

 

1.) Front end: You'll feel it in the steering wheel more than anything and will be left and right vibration.

2.) Rear end: You'll feel it 'behind you' and it will be left to right vibration.

3.) You won't know where its coming and it feels overwhelming: axle shafts or something similar is causing a front to back vibration.

 

So far no one has described exactly how the vibration 'feels' in details (from what I've read). Also its pretty sad GM can't narrow this down.

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

Nearly every rear end was build defectively that went on 2014-2015 Sierra and Silverados.

 

It is a known fact that American Axle messed up when supplying these. Ring/pinion gears were not built to spec, causing vibrations and grinding/rubbing noises that will come from your floor and or steering wheel (mostly during deceleration).

 

I have had the rear axle assembly swapped out with new on 2 trucks so far.

 

I feel bad for people that are not aware of this because years down the road they will have failing axles, chances are, when the vehicles are out of warranty.

 

In my eyes this is criminal and a lawsuit should happen eventually...because rear axles are not cheap to replace and GM KNOWS THEY ARE BUILDING TRUCKS WITH BAD AXLES.

 

Shameful.

If this is true, GM should be able to hold their supplier accountable for the costs to replace the rear ends, no?

 

Does anyone know if this was a new supplier or a new line for our trucks? Do they make all gear sets or just certain ones?

Aam has been making gm's rear diffs for a very long time... circa 1994. They make rear ends for FCA (Chrysler) as well as pretty well every other manufacturer out there.....

I had a 2014 GMC LB CC Z71 that I had to trade in last year because we bought too big of a RV to safely tow with it. Truck drove great and did not have the high speed vibration issue but it did vibrate very badly on certain roads (freshly paved with slight oscillations). Despite this issue I really loved that truck. One road near my house made it feel like it was coming apart at about 45-50 mph - a little slower or faster and it was fine. I suspect the stutter bumps were matching a frame frequency and having a party. In the replacement 2014 Cummins Ram the road just feels a little bumpy, same in our Tahoe and the half ton loaner Ram that I had last week. This is a frame problem.

 

Thinking that this is going to be fixed forever with a new rear end or super road force tire balance or better rims is insane. What happens when your front tires wear a little funny and get out of balance just from driving them? Or you go to Discount Tire or WalMart to get new ones in two years and all they can do is spin balance them? I guess they will be popular at the Sherwin Williams stores for shaking paint cans. GM needs to fix this problem by adding vibration dampening cartridges like Chrysler had to do (and from what I have read Ford will have to do on their new ones as well). This is really sad because GM makes the best looking trucks by far and when they are not shaking they drive great.

My GMC sle dbl purchased 7/14 and repaired with a new rear end in 9/14 continues vibration free at 20k miles and 4 tire rotations.

No Ford, FCA, or Toyota looks so good and delivers terrific fuel economy.

I'm just going to add a change slot to my dashboard, I'll stick a quarter in every time I want it to vibrate. That way I can call it an option, that's the difference between an issue and an option right ? You have to pay for an option :)

Do they require rear end replacement with 4k miles on the clock?

GM has provided the vibration feature as standard equipment on a select number of trucks.

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.
