High pitch humming noise when driving.

We just had this high pitch humming noise start after our 60k maintenance. It only happens when the car is physically moving - not when you’re in park and hit the gas. The spinning noise gets faster the faster you go and it’s loudest under 50mph. Any thoughts?

Does the noise change or stop when you let off the gas or hit the brakes?

Wheel bearing possibly. If coming from the rear can be rear gear.

Maybe check the fluid level in the rear gear housing.
