  1. Yesterday I changed the front Diff with Mobil 1 Synthetic 75w-90 and the transfer case with Royal purple synthetic ATF. Both of the fluids still had great color and the magnets had minimal filings on them compared to some pictures/videos that I've seen online. On my way to work this morning I Swapped the transfer case selector to Auto and I still have the noise that I've described. I'm assuming that it is the Module as some on here have suggested. On a side note, I'm planning on changing the Rear Diff Fluid soon. Rather than removing the cover and dealing with the gasket, I may pump out as much of the fluid as I can and refill it. I may use Mobil 1 or Amsoil sever gear for this job.
  2. That’s exactly what mine has started doing. Sent from my iPad using Tapatalk
  3. Thanks, that could be what I was hearing. The pitch of the sound would increase as I press the accelerator pedal and would quieten as i coast.
  4. I'm planning on swapping both diff. fluids as well as the transfer case soon to see if this will help. Any advice on what brands or weights that I should go with would be appreciated.
  5. It goes away when i swap it to 2 High.

    I'm planning to change both of my differentials and my transfer case fluids soon. My truck is a 2014 5.3 Denali with 73 K miles. Should I be concerned swapping to synthetics with this many miles. I've heard that gaskets are more prone to leak after going from dino oil to synthetics on vehicles with higher miles. Any advice on oil types and brands would be appreciated as well.
  7. I swap it to Auto during rainy weather and sometimes forget to swap it back.
  8. Mine hasn’t always made this noise, it just started. I’m going keep it in 2 high until I have time to get it checked out. Sent from my iPad using Tapatalk
  9. I have about 73K miles on my Sierra Denali and have recently developed a whining noise when I have the transfer case selected to AUTO. Has anyone else experienced this issue, and determined what the cause is?
  10. Recently I've noticed some drive train noise in my 2014 Sierra Denali with my transfer case in AUTO. It goes away if I select it to 2WD. I have about 73 K miles on the truck. Just curious if anyone else has experienced this issue.

  12. Went back a few pages and found the part number.,,. Sent from my iPhone using Tapatalk
  13. Does anyone know the bulbs part #? My local dealer ordered some for me, but has stood me up on doing the fix. Hoping I can buy the bulbs and have the dealer that I bought the truck from install them. They said they would reimburse me if my local dealer will sell them to me. However, I want to be certain they ordered the right part number.. Sent from my iPhone using Tapatalk
  14. If I'd know that the front bumpers were this prone to chips, I would have had a protectant applied the day that I bought the truck.
  15. I went to a local dealer (not where I purchased my truck). They haven't heard of the TSB but looked it up and ordered new bulbs. My 11th Digit is a G and I bought my truck last June. Hopefully I can get the 4x4 recall and my GPS fixed at the same time. I've only had my headlights fog up once, but I might get that addressed as well.
