I have this noise under part throttle from 40-50mph and I cant for the life of me tell if this is a real issue or not. Ive read numerous threads and watched videos on the t-case whine but those videos sounded almost like a fire truck and were really loud. This sound is faint whiring noise that doesnt get louder the faster I go and its only between certain speeds (40ish-50ish). I just purchased the car and havent gotten the chance to check the tcase/diff oil yet.

You can tell when i step on the gas (around 3 seconds and 16 seconds) cause my fuel economy gauge goes down.

Here is a video of noise
