Squeaking whistling noise while driving

I’ve been intermittently having an issue with a whistling noise. It happens more when accelerating. Hitting the brakes or stopping stops the noise. It sounds almost like a belt noise but I can’t find issue with any belts. I think it comes from the rear of the vehicle but hard to tell since it will only make the noise while rolling. I’ve attached a video. Anyone else have this problem?

Sounds like engine...doesnt do it at idle at stop? Could check ujoints, might need greased

 

No noise at idle, I’ll check u joints thanks

 

Could be brake wear indicators also

 

Damn that's bad. I dont have any educated guesses. But maybe the driveshafts/ ujoints or even the carrier bearing are worn or rubbing

 

Yeah brakes are good, I thought of that but brakes make sound go away. I’m going to get a grease gun And try out the u joints I’ll update if that fixes it, it’s strange because I can ga a week or two and no sound then it will do it for a week straight

 

Guessing it’s no longer under warranty?

 

drivetrain warranty is for 6 years or 60,000 miles.

 

That’s right, power train is 60k I’m heading for Toyota dealer! Thanks I forgot about powertrain being more mileage than 3/36

 

Update:
Just got back from dealer and wanted to update everyone. NYCtaco52 you were correct. They replaced the carrier bearing and a U joint. This problem was hard to chase down for me and the dealership because the noise only happens when its rolling and has a load on the drive train. When they put it on the rack they never could get it to make the sound. It was all covered under warranty. and FYI my truck has 47000 miles on it. Thanks for the help all.

 

Good job on updating and closing the issue for future people.

 

Thanks for posting. I have the exact same noise and it's been driving me CRAZY!!! Unfortunately I am over 60k miles. Do you know which U joint they replaced? Could it have been just the carrier bearing?
Thanks!!!

 

I have the same issue with my 2022 TRD sport, the dealership said it isn't loud enough to do anything about it, prolly gunna have to pull a Karen

 

So I took my truck back to the dealership, as it was making the same noise as the video, mine funny enough turned out to be the spare tire so they lubed it and tightened it and the noise is now gone, hope this helps some of yall
