gjk1932 I think there is a problem with all Goodyear tires that come on these trucks. My truck came with the Goodyear Eagle LS-2 tires. I am glad to hear that some of you have swapped the tires to another brand and have either fixed the issue completely or reduced it to a non-issue.

 

I have no further updates since my last post since I haven't made any trips after getting my truck back three weeks ago. I've been working 70+ hrs a week and haven't had any time to just get out on the road to test the tires or make a trip. I may get a trip in this weekend, so I might have a conclusion on the fix I got next week. I've been thinking about replacing the tires but haven't had the time to do so or the want to spend the money. I'll make that decision after I get a long trip in.

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

Update: Just was informed that GM has advised the dealership to change out the Torque converter and the Transmission Control Module. My truck should be ready on Tuesday. In the mean time they have given me another 2014 sierra as a loaner....I am interested to see if in the time I have this truck if I notice the same vibration.

 

As far as tires go, I think we may be talking about two different issues here. The problem I am experiencing (as well as some others on this thread) is intermittent at speed, not a continuous vibration that occurs above a certain speed. If the later is the case, then yes I agree, the first thing I would look at is a problem with tires (or possibly the drive shaft). The problem I am having does not occur every time I am at a certain speed or operating under the same conditions (i.e. it only seems to happen under moderate power between 50 and 65, but does not occur everytime I am under moderate power between 50 and 65).

 

As always, I'll keep you posted of the findings/results.

My z71 package is pretty stiff as well and ended up being stiffer than the std package truck I test drove. I had to have the Z71 grill, so shocks I can change back to twin tube for smoother ride at anytime:)

Well it has been about 200 miles since the dealer swapped the goodyears for Bridgstones and yes the wobble is gone, but I have to say this is the worst truck ever. The steering wheel is not smooth there is a constant slight vibration that is not tire related and even the smallest cracks in the road feel like you are hitting giant pot holes and the whole truck bounces. Every little thing is felt directly through the steering wheel.

 

If anyone is reading this post DO NOT BUY ONE OF THESE!!! I have had at least 10 chevy and GMC trucks and never had such an awful time driving a vehicle as this one. Can't wait to trade out of it.

Mine is quieter and smoother than my last three Infinitis. Sounds like you got a bad one.

What are you driving?

 

Your steering senses what the tires send thru to the steering components. Save your trade loss by going and getting some good Michelins LTX tires and a good road force balance. Brigs are not that good. Discount gave me a good price trade on mine. I drove from the dealership straight to Discount and had Michelins put on the same day I picked up my truck.

 

then if we can find some Bilstein 5100s for these '14s you should be good.

Just to update everyone on the rumble strip vibrations I was experiencing. I got the truck back 2 days ago and so far so good. Here is what the dealer reported:

 

Road tested vehicle and found possible tire/wheel vibration. Removed all four wheels and road force balanced to find one tire out of range. This tire was replaced and then vehicle was road tested again. The vibration improved but was not eliminated. Checked for TSB's and none were found that directly addressed this concern. Contacted TAC and TAC suggested to utilize TBS PIP5149B. I followed all instructions of this TSB, checking for excessive spark retardation and connecting rod oil squitter condition. There were no conditions observed. TAC then directed me to utilize DOC ID#2102430 where I checked the operation of the control solenoid within the transmission. When commended to the on position, It registered full pressure and when commanded off it registered 0 pressure. After completing all tests found that TCM could not be 'pulse-width' tested, only command on or off. With these measurements we determined that the TCM was sending an erratic signal causing the torque converter to be commanded erratically. This caused potential damage to torque converter. Therefore, I replaced the TCM (Signal) and torque converter (damaged internally). Road tested vehicle; now operating to GM specifications with no vibration when tested under the original conditions.

 

I have also noticed that the "floating Tac" condition I had earlier is no longer present.

Yes. When the cruise was set on a steady up hill climb the tachometer would float I.e. kind of fluctuate in a range of RPMs; not hold steady.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      By Black02Silverado · Posted

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
