Front End Noise

I have a 2020 Tundra that I bought new. At roughly 15000 miles i noticed a humming noise coming from the front.. ( sounded like a wheel bearing going bad) I went to the dealer and they checked the bearings and reported that they were all good, and the noise was a bad tire. So, I have kept driving it.. had the noise checked by another Toyota dealer. The put it up on the hoist, checked the bearings ( which they said were all good) the humming noise went away for a little while, after they had it up on the hoist, then came back. I had new tires put on, the noise was still there, but seems to disappear for a few miles.. then come back. Then I discovered that if you engage the 4 wheel drive.. the noise disappears, but when you take it out of 4 wheel drive the noise comes back. Went back to the dealer again ( because now I'm at 57000 miles..) and complained. I took the service manager out for a drive and let him see what was going on.... and they have no idea what the problem is. They want to call a field service rep?? WTH! Anybody have any ideas? Please and Thanks!

 

I haven't been around here very long, but that sounds similar to this issue. Seems strange with such low miles on the truck

 

2021 tundra same deal with 8k miles las April 2021 dealer replaced front differential and front left wheel shafts . This week same issue now 27K miles dealer to replace the same with shortage on parts ,parts on order . Discouraging for new pricey truck
