2010 bad wheel bearing 154000 miles

Hi every1
I got a 2010 prius III and I think I got bad wheel bearing but I don't know which wheel is bad tho. All I know is that I heard those noise and its very loud and only on freeway over 50 miles per hour. If its under 50mph, the noise is not as loud. Local driving like around 40mph, the noise almost un-noticable.

The noise I hear sounds like this mine sounds louder on youtube title -

The parts I need $64 each (The lowest I found) @ 1A Auto

I checked some youtube videos, Its probably not as easy as it seems. I doubt I can do it all by myself. What do you think ?

 

I think it's most likely front ...it could be rear too ...don't know
