if it were the power steering I would think the issue would be repeatable when I turn the wheels full lock left or right since the pump is working its hardest then. but i have to be moving at low speed to hear it, and it also doesn't appear at high speeds (which I assume the road noise is just drowning it out)

I wondered if it were the diff or the wheel bearings/hubs.

Definitely the dif.
