Couple weeks ago I traded that 2020 in for a 2024 and so far this one is completely silent of any noise in or out of 4WD. I'm just curious what Toyota might have done to fix this issue or am I just lucky for now. I will know for sure as miles increase.

1. The T-SB for this issue states there was a production change that fixed the issue, so your '24 should not have the problem.
2. The T-SB states that the noise goes away when engaging 4WD; that is one of the ways you diagnose the issue.
3. I am always leery when a dealer tells me something is "normal" when you have a problem described in the T-SB. (T-SB-0012-19).
Edit: The T-SB says the problem was fixed by a new differential carrier assembly. It gives the new and old part numbers for that.
