Hey guys I’m new here. I have an 04 Yukon Denali I just picked up. Been doing some stuff to it getting it ready to roll and I have this humming sound when I push the throttle, and when I’m slowly coming to a stop. I can feel it in the steering column too. I would attach a video but I’m not sure how to do that. Hopefully someone has had the same issue and can point me in the right direction. I did a trans service and it didn’t get better or worse. Thank you!

When moving. Around 40 mph transmission is in 4th and even lightly touching the throttle, it makes the sound. I’ll post the video right now
And it doesn’t have to be at 40 exactly, that’s just when you can hear it best
Here you can hear me feathering the throttle. When I let go of the throttle it stops. But if I press on it it comes back. Also noticed yesterday coming to a stop it sounds like a lower pitch version of this and it slows down with the truck slowing down.
sounds like the pinion bearing making noise, has any work been done to the rearend?
Nope just got it. Was going to go and do the service on the front rear and tcase. Just did the trans and a couple solenoids. Really hope I don’t have to fix the diff. I’m already doing the rear main seal and plate this weekend! lol
