I have a 2003 Toyota Sequoia Limited 2WD that has a lot of road noise. It makes a humming sound similar to mud tires when going at speeds above 20 mph. I have ruled out tires/Front bearings/hub because i changed all of them. I use Yokohama Geolander H/T-S if this info helps and the previous tire change was to the same brand and model as the stock tires which still made that noise. Just changed it about 150 miles ago to rule the tires being the cause of the noise. It gets progressively louder as speeds increase. I dont think it is the rear bearings affecting the front to make that noise since it is a 2WD version (maybe I'm wrong?). I am exhausted from trying to figure out the noise. Any suggestions on what it may be or have any other people having same problems? Thankyou

cupped tires can make noise rotate them to the front to see if the problem goes with the tires they do have wheel bearings that go bad and the rear diff but the rear diff will change noise when your on and off the gas
If the sound follows vehicle speed and not the engine you could be hearing u joint noise from the Driveline also. Will get progressively louder with speed.
You say it does it in gear or not? I ASSUME it only makes noise when the car is moving? and whines according to road speed? Get wheels offthe ground and spin each wheel. now grab the coil spring above each wheel and feel for a vibration.
Tires could be cupped or worn due to not being rotated regularly, and or alignment/balancing issues, this would cause this sound as if you have 40" Mud Swampers on it. Another possibility is a wheel bearing going bad, but being it's so new, would be doubtful. If tires are causing this noise due to the above, the only thing that would get rid of the noise, is new tires unfortunately.
it can be any of the above, rotate the tires and see if the noise location seems to change, but the last thing i would suspect is the CV, they just click when turning, the wheel bearing is my choice here, they roar, tires make a diff noise.
I have the same problem and it turned out the rear wheel bearing wad the culprit. Not a cheap fix (around 300.00) since you have to replace the whole assy.
