wmgeorge64 keep me informed how your repair on the rearend goes. I have read many posts whereas the rearend could cause a noise to travel through the hollow driveshaft and sound like it is coming upfront. My dealer is replacing the transfer case Monday, I'll find out by Tuesday if that corrects the issue. It's a damn shame that GM couldn't send a TAC rep to the dealer to help pinpoint the issue, instead they will have thousands in charges to try replacing different items. Hell, I'm within 30 miles from there Tech Center and Headquarters, they really need to step up their actions.
I was thinking that as well, removed window shields and tonneau, still noise. It was windy here last week, no change to noise going with or against strong winds. I do feel slight vibration on the floorboard when the noise is there. Dealer is trying to find the source as well.
I have a 2018 Sierra for less than a week, took it into dealer for humming noise at 70-80 mph. Doesn't matter if on throttle or off, in gear or Neutral, noise still persists between 70-80 mph. Sounds like road noise, but tires and wheels were road force balanced and replaced, it's not the wheel bearings. Dealer not able to pinpoint the issue due to wind noise to strong at that speed for the chassis ears. Does not duplicate the issue on hoist. Does anyone have any ideas?
Update- possibly Vosla bulb burn out on passenger side headlamp, looked underneath and seen the fog lamp wiring plug hanging, plugged it in and fog is working. Didn't take the time to pull out air filter box to look at headlamp yet.
2014 Sierra SLT - Front RH (passenger) headlight and fog light out on RH side only. Tail lights and LH front lights work. Anybody had this issue where both the headlamp and fog light went out on one side?
