4th Gen Differential Howl

[GR90]

Having this same problem on my 2025 TRD Sport. Sounds like the exact problem the 3rd gens had. Slight noise coming from the back only when under light throttle at 50-59 MPH. If you let off the throttle or reach a speed outside of 50-59 MPH it goes way. Debating what to do next as the truck only has 400 miles on it.

Has anyone else run into this yet?

Here is the noise for anyone interested. When I say on it means I am on throttle and you can hear the noise and off means off throttle and the noise goes away.
