  1. One thing i did come across when i was fixing my truck was a shop called TCS transmissions . One guy that worked there had a 2016 sierra 1500 same as mine and had the "shake" . He said there were a couple parts in the transmission (6l80e) that were garbage and that they caused the vibration . He reportedly replaced said parts rebuilt his trans and put in some upgraded parts and there was 0 shake after .
  2. Its the fuel pump and is 100 % normal under certain operating temps . 2016 with 120k and no issues here .
  3. Axles felt a lot smoother but the shaking was definitely the drive shaft and yes i had a higher quality unit made up. 6" unit 1/4" thick aluminium .
  4. Mine was slightly the same way before i did the driveshaft and i think it has to do with rear end and trans temps that being said i have not had the issue since swapping the driveshaft .
  5. The factory driveshaft is 1/8" thick i don't think you could machine it at all . The unit i had made is 6" diameter and 1/4" thick .
  6. From all the reading i have done i have not seen anyone re-balance there driveshaft and have it fix the vibration the issue is the driveshaft is made of paper thin aluminium and its full of cardboard . Because the driveshaft is so thin it resonates vibrations badly.
  7. Sometimes lifters collapse when they don't fill with oil properly maybe you had a lifter collapse partially during V4 mode and spring up in V8 mode ? I would 100% have the afm turned off.
  8. Sounds like you lost your serpentine belt . Probably went into fail safe mode and shut everything down .
  9. Had one made from a company called Pats drive-line I am in Canada so a lot of the american options are to pricey for me . 680$ Canadian i paid . 6" round aluminium one piece unit .
  10. This is how mine was when i was fighting to figure out what was causing the vibration . Balanced the wheels got a little better changed the axles got even better then was 100% gone with new driveshaft .
  11. What i really mean by all of this is that i think a lot of people say they have a vibration issue because they can see the console move on the highway .. If you had the same truck but with a flow through centre console would you even notice the vibrations ? i know before i had my truck fixed the floor and seats didn't really vibrate more than a normal truck but the lid for the fold down seat always shook like crazy .
  12. Yes the big console with no jump seat . I rode in a friends 2016 with the flow through console and it felt a little rough on the highway but not bad and zero centre console shake .
  13. I think someone posted a 2017 driveshaft on here and it did look different than the 2016 down models . That being said i dont think i have seen anyone with a flow through centre console have this issue which i find very interesting ..
  14. I would ask them to check the run out of the driveshaft and or the rear axle shafts .
