I have a 11 silvy crew 4x4 with 8000miles

When I take off and stop (especially in drive thrus and parking lots), I get this sound from the rear of my truck. It is only when its in gear and it sounds like a spark/crackle noise. Kinda like an electric bbq igniter sound. The dealer heard it and said its being amplified through the driveshaft. I was told that engineering is aware of the problem however there is no fix as of yet.

Anyone else run across this? Thx

- Missing thrust bearing? And oil selection

  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.

  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.

  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,
