How do you tell the difference between a bad wheel bearing and bad differential bearing?

    I have a 2008 Toyota 4runner that is making a high pitch noise from the backside. Everything online says its probably the wheel bearing. But the mechanic i went to said its the differential and wheel bearings and he couldn't help me...that I had to get it fixed at the dealership. Any thoughts or same experience?
