Loud squeaking right side

[Phrezy]

I'm coming from the imports side of town and don't know much about these.

I got a 2005 explorer xls. The rear diff seal blew out and i had it fixed. It was making a squeaking sound when that happened. After it was all said and done I still have this squeaking sound coming from it seem the right rear wheel. It has become louder and mostly only heard 35mph or fast. Could this of caused more damage to something else? Bad bearing?

bearings tend to hum and brakes squeek. poor quality pads/rotors and or excessive wear can cause the "warning tab" to touch the rotor causing a squeek
