Subaru 2000 Outback Whining Sound when cold

When I start the car on cold mornings (30s and 40s), I hear a whining sound from the front that gets louder as I accelerate. The noise is also pronounced when I turn. The noise goes away once the engine warms up.

I don’t hear this when it is relatively warm(50).

The only fluid level I have not been able to check is the diffential fluid. All other fluid levels are fine!
