My truck has been at the dealership since yesterday to put on a set of stockers to let me drive around so they can prove it's the nitto tires that are causing the vibrations.

Well my friend, my days of sierra vibrations have ended. I traded her in for a 2017 ram copperhead sport. They paid my truck off and lowered my payments and this thing is smooth as silk up to even 90 mph. The ride is more comfortable, and just seems like I got more truck for my money. I wish u all the best of luck on ur journey of getting ur vibes fixed. Take care.

So I rode around with the tech, there was a vibration could see it in center console he even said he feels something. Left it overnight, they loaned me a 2017 double cab, holy shit that thing shook LOL, would have been embarrassed selling that to someone, anyway, he called me next day and said its ready. I get there and he tells me Pico scope was within specs and operating as normal. I record a video as I get on highway and the waterbottles were shaking, console was shaking. What a joke. The "service advisor" guy was a dick to. I'll reach out to my sales guy and see if he can be of some assistance, cant wait until I get my 94 out from storage for spring, atleast shes smooth as silk.

Call GM at the number in your owners hand book!

Ask them to get involved, that your truck and steering wheelshakes and it is causing your hands to loose feeling.

That should get them interested!

Drove the Silverado to Columbus Ohio Friday was ok going down , only went up to 71 MPH on the interstate . Came home Tuesday morning truck running smooth at 70 MPH and decided to take her up , ok at 71 , took to 72 not perfect , took to 73 MPH and the steering wheel started shaking , went back down to 70 smooth again , back up to 73 MPH and shaking again !

 

I have been experimenting with my truck and know what is causing the shaking up front ! We all know that GM engineers read this form so I will wait to see if someone has the balls to contact me but I will not hold my breath !!!!!!!!!

 

I'm sure they will not believe what is wrong

 

 

I had to log back in just to reply to this one. All hail this guy !!!! The genius figured it out, the issue (at least in his case) is the nut behind the wheel LOL

Hey C6Bill

 

​You sound like a typical engineer that never got out of his baby crib !

 

Note some people just get into what ever they are driving and never pay attention to what it is trying to tell them , hint I was a farmer and being a farmer you listen to your machine !

​Hey bill I forgot to tell you the real important stuff , I filled up about 1 mile from the interstate and drove about 136 miles and my MPG was the lowest ever 17.1 !!! Past trips same road well over 22 MPG ,,, hint my guess GM will be getting big repair bill soon as a machine can not stand the abuse this truck has taken !

Stand down Softtail, this guy has GM right where he wants them. He's gonna go all whistle blower on them LOL

He's thinking I tracked his brain waves and busted his windshield with my engineers baby crib. That will teach him to leave his foil hat off for too long.

 

 

Here's some more yummy troll food for him.

    • Ahh, sorry about that - I got some bad info. Newdude is correct. That's what I get for working 13 hours straight ... on my "vacation", lol.   Should've checked the files I had instead of the internet.   Anyway ... this is GREAT news, since this would've been an absolute friggin nightmare to get working.   I don't think the lack of VVT is causing this - you've got another issue. Wiring, I'm betting.   I'm telling you right now, your computer isn't bad. If it worked before the swap, it's working now. You need to do some more (better) diagnostics and figure out exactly what you're missing. Did you test every wire directly at the MAF? Have 5V reference? Ground? If you're reading ZERO g/s, your Hz isn't much use - it's going to be the wrong value anyway. The MAF is not working, and you need to find out WHY.   I got this off the net, so VERIFY first: Pin A: Black (BLK) wire, Circuit 552, serves as the Sensor Return (Ground).  Pin B: Tan (TAN) wire, Circuit 472, carries the Intake Air Temperature (IAT) signal.  Pin C: Yellow (YEL) wire, Circuit 492, is the primary MAF Sensor Signal output to the PCM. Pin D: Pink (PNK) wire, Circuit 339 or 539, provides Ignition 1 Voltage (Power).  Pin E: Tan/Black wire, Circuit 552 or similar, often associated with the Intake Air Temperature ground or signal return.  Global-A list: https://postimg.cc/KKJnQC85    
    • Correct....the end user can't reach to Realtruck directly like they can if they purchase a Bak, Undercover, etc...  It has to go through a dealer.
    • It is 4wd. shop told me it is the slip yoke. But not sure.
    • No, I did not tune out vvt. From what I read it should still be able to run without it, it'll just lose some torque/power.    I can see how that would make it not run correctly, but why would that cause the faulty MAF readings?   EDIT: I just ran a quick test and checked, and as I expected, the computer sees that the VVT cam phaser solenoid is not present, and throws a code for it, and does not try to change the cam angle at all. Commanded position just remains at zero, 100% of the time. This makes me think that the VVT is most likely not the cause of the problem though if anyone has a different/better explanation, I'm all ears.   UPDATE: I was able to find that my scan tool does indeed support reading the frequency (hz) off of the MAF (I thought it wasn't supported but turns out I just didn't know where to look for it). I noticed that regardless of engine state it always however this Is not what I observed with my multimeter. Like I said before, the MAF seems to put out a normal signal during cranking and then the signal drops to a very erratic reading once the engine is running. It seems from what my scan tool is telling me that the ECM is not recognizing this at all, and just reads 0 Hz 100% of the time. This pushes me towards the the PCM itself is faulty. I I have the PCM out of the 2007 donor vehicle, which I may try to connect and program (it's only ~50 bucks to get the software for a one-time programming)
    • Did you tune out the VVT?  07-09 they did not have VVT.  2010-2013 they did.      If you haven't tuned it, its trying to adjust cam timing.
