hmm K sounds good i have a appointment set for next week at a local drive line shop to have my driveshaft checked maybe ill have them look at my diff at the same time . Thanks for the reply . 

Any update to the driveshaft and rear gear check?

 

I also noticed this video today. I talked with Driveline Performance last winter and they mentioned they were testing with the driveshaft concerns on the Chevy Shake Issues but they really shocked me when they mentioned that they were testing with custom axles which they mentioned were thinking of more of a culprit of concern.

I have not had my driveshaft balanced yet switching my axles made a hugee difference almost perfect i will be buying a 2 piece driveshaft eventually so i am not going to waste my money on getting mine re balanced . This way if it is a backlash issue or a balancing issue the 2 piece unit will get rid of the vibration transfer .

Just know that Driveline performances doesnt make a 2 piece for 4 wd vehicles.

 

What axles did you order and where from? Have a part number?

i ordered a 5 " diameter aluminum one piece instead will be here this week from my local drive line shop .

I used to have a lot of input in this thread with my 2016 silverado. It is a 2wd crew cab with a 6.5' bed. So from the factory I have a 2 piece driveshaft and I still have a shake/vibration. It really is very minor now after all of the parts I have thrown on it. First started at around 8000 miles. I just thought it was something with my spindle lift and/or rear block. It wasn't. Since then I have had my OEM 2 piece driveshaft balanced to find it was perfectly fine. Very minor unbalance but it was balanced out and still had the same vibration. Then I swapped the rear 3.42 gears for 4.10 and also swapped out the axles. Of course this changed the speed output of the driveshaft to spin more at highway speeds. It basically brought the vibration down to a 68mph area but still there. Although, the axles really did seem to help the most in cutting down the vibration. I don't have it all the time and when its there it is very minimal. I think its barely there now or due to being at 65k miles now I have gotten used to it. So regardless of what people say swapping to a 2 piece "fixes" it I highly doubt it. 

 

Also I need to add that I really have a strong feeling the shake is in the programming or ABS system. I also have blackbear performance tunes installed and for my first initial tune he sent me I had zero vibrations. I had him modify the throttle response back down for me a bit and when I loaded that tune it seems the vibration came back.

Someone I was talking with brought up a very interesting issue. He asked if all of the vehicles having these issues came from the same manufacturing plant. So I mentioned that to some others and what has been an interesting find so far is that every vehicle VIN that starts with  the number '3', was built in Mexico. have confirmed now that three of these vehicles VIN's start with the "3". So out of curiosity, and anyone willing to post, does your VIN start with a 3? Not going to make any difference but sure would be interesting , at least for me to see how many others do. I had to get winter tires and got some BFG KO 2's. They are a bit hard to balance so unfortunately i get some tire vibration now but when spring hits will try some of the Michelin's. The BFG's are the best I have found for where I live for the kind of snow and weather we get. Was concerned the Michelin would not be good as there is not anyone else around here that has them on anything.

Mine starts with 3 and has it

Mine starts with a 1 and has it I believe it was assembled in Indiana 2018 LTZ 2 wheel drive

My understanding is that the crew cabs ALL come from Mexico.

Great to hear. Dealer said my issue is the torque converter I will see later this week if it solves my vibration issues

Yukon Axles and new 5" aluminum driveshaft 1 piece .

You got the Yukon’s and shaft at same time? Which would you suggest getting done first? Are the 

Yukons for stock application truck?

Did the Yukon Axles first which got rid of 90% of my vibration the driveshaft got rid of the rest .

    • Most thermostatically controlled ATF systems use a 'wax' pill just like the one in your water thermostat. They work on the expansion volume of the wax and the pill is constructed in such a way as to limit the travel to remain within that range. This means it has an opening temperature often called the 'cracking temperature' and a fully open temperature. For whatever reason oil is designated by it's fully open temperature and water by it's cracking temperature.    Between the two it the "Regulating Temperature" The entire range is about 20 F from closed to open. In your example the lower limit, opening point of 145 F then has a fully open temp of 165 F and a throttling temperature of 155 F.    Thing is, the throttling temperature needs two things to work properly. Enough system load high enough to reach the minimum and a heat sink (cooler/exchanger) large enough to prevent any load applied from exceeding the fully open temperature.    If your system exceeds the fully open temperature it is screaming MORE COOLER.    Here is the silly part of the whole thermostat system where the oil is cooled/heated by the radiator. Nothing is flowing to that system until the oil temperature reaches the cracking temperature unless it is equipped with a minimum flow bypass orifice or a bypass built into the seating surface of the plunger. That system meant to get it up to temp quicker isn't doing a thing until WORK drives if from ambient to cracking temp. One a cold winter day, like zero F, it may never get hotter than about 110 F. Sometimes not even that.    People forget or are young enough to not know that until this millennia transmissions were cooled by the radiator cold tank alone and without a thermostat at all.  In the 50's they weren't even cooled. OEMs learn everything the hard way.    When an OEM tells you the trans "Works best" between 175 F and 220 F it means works best for THEM. The transmission thermostat is fuel play. If you watch you trans temps like I do you will learn that it may take a hundred miles if you are not towing and not driving more than say 55-60 mph on a zero F day to even reach 120 F and it might sit there all day if it's colder. Yet if functions perfectly over about 100 F. It may need to get a bit warmer for the fuel and spark maps to go without an multiplier.    Worry more about too hot. Use a cooler large enough to put that thermostat in range.         
    • Around 2008 if memory serves they took sulfur out. That was when diesel went up. 
    • Question for you Grumpy, why is diesel so much more than gasoline? Seems to me that it may be slightly a little less refined than gas and it doesn't have 10% alcohol which presumably lowers the price of gas
    • Thanks, so being a different beast altogether, anyone know what the "optimal" temp is for the 10L80/90 for proper shifting?
    • How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.
