Where should I get wheel bearings for my 2004 yukon denali?

I will go with a couple guys here ... stop firing the parts cannon. The front diff was expensive even if it's a used one. Since that change made -0- difference i would say it's not the issue. Unlikely two would have the same defect, but it's possible.
You said it makes the noise under load but diminished when in neutral, moving, however still present. So it's a drive train noise, affected under load. Could be universal joints, transfer case bearings, maybe transmission. I believe you need a shop to help as we're only pointing at this or that right now. You sound like you are interested in diy, so just need a diagnostic evaluation. I don't like dealers, so a trans shop, or auto repair facility will get there. Talk to them in person, tell them what you're trying to accomplish.

I have a pretty loud humming noise coming from somewhere under my 2004 Yukon Denali, and I am currently praying that it is just one of the wheel bearings going bad, though its been making this noise for months now. I have replaced the front diff as I have been told when they reach higher milage they tend to fail because of poor maintenance from past owners, and the fact that 04 Denalis are 4wd all the time but that didn't fix the hum. I've also replaced the front left wheel bearing, because I believed that was where the sound was coming, I seemed to go away for a couple of days after that, but I also wasn't driving it as much then so I'm not 100% sure. I am kind of worried that it could be transmission but the liquid doesn't look bad, and I feel that if that was the case it would have failed long ago. If it helps, the sound only happens from like 40-50 mph and 60-70mph, however it does occur at other speeds, it also ONLY happens when I'm pressing the gas, and if I press the gas lightly, like just a tap it sounds much louder. I have heard of the trick to shift it into neutral while moving to see if it goes away, and when I do that, it does pretty much go away, but not fully. I'm no car guy but that does make me worry that it could be some sort of torque convertor or something transmission/diff related. I would like to start by replacing wheel bearings, and I'm wondering the best place to buy them, because I don't wanna get a part that is going to break on me in like 2 months. If it helps I currently have no dash warnings that are visible, and for the most part it drives okay, I have felt a loss of power, and a lot more engine noise, but that I believe that could be age.

I went with new Tinken Hubs for my '02 Z71, great product, easy to install.

Those mile per hour noise reminds me of bad tires.

I wish but I just got a new set of Goodyear Wrangler Workhorse HTs on it about 2k miles ago, didnt change sound much

Yeah i think that's gonna be the plan, if it is anything to do with the drive train i sadly wont be able to do it myself, as i just don't have the tools i used to have before I moved. There's a drivetrain specific shop pretty close to me I'm gonna go too, I guess Ill know more soonish.
