2021 Taco off road 4x4 with 2,700 miles and rear end whines when feathering throttle. Anyone else having same Issue?
Toyota changed rear differential but still exists.
 
I wonder if it’s not the rear end making the noise. If they replaced it and that was the issue it should resolve. Check the fluid and make sure that it’s topped off.
Grease the drive line zerks.
 
Seems its mostly related to the trd trucks. I understand the differential isn't the same as a sr or the sr5 ones? I guess its normal if you can live with it. Those trucks develop other vibration issues to from what i've been hearing.

If it does it around 50-60 miles an hour and yeah IMO it's normal
