22+ Tundra rear end noise

Howdy fellow owners! I recently purchased a 2024 tundra about a month ago and I love the truck so far except for one thing, the annoying noise coming from my rear end! It is only during acceleration and gets worse the faster the truck goes. Terrible on the highway! I only have 1,000 miles on my truck and it seems to be getting slightly worse as I put more on. I took it to a local Toyota service center since it’s under warranty and they agreed that there is an unusual noise coming from the rear end. Due to the fact the truck is under warranty the dealership needs permission from Toyota to perform any kind of fix or even check my diff fluid! Toyota told my local service center today that the noise is normal and the truck should be sent home with me. I called Toyota hq and complained and it seems like they will give in, I have a phone call with a higher up Toyota guy about it tomorrow. Does anyone else have rear end noise issues in 22+ tundras?
