Whirring noise while driving

[bmidd]

2020 with ~70k miles. Audible whirring noise when applying gas while in motion, went away when you let off the gas. Dropped it off today and they said rear diff. Transfer case also has a bad leak, so they'll have to tear into that. After they did the valve body replacement they neglected to fill the trans to the proper level, we didn't discover that until about 15k miles after that repair. Started shifting weird and having shift flare on the 2-3 and 3-4 shifts primarily. Took it to a local friends shop and discovered it was almost 2 quarts low. They'll be replacing the diff and will let us know about the transfer case and will be flushing the trans fluid, we'll see if they can manage to get the it filled properly.

I'm hoping mine will stay out of the shop for a while! I had my front axle disconnect repair, rear differential replaced twice and transfer case twice and all before 55K miles! I'm not ready for a new car just yet so I'm hoping to hold out another year or so with the remaining 2 years of ESP bumper to bumper warranty.
