So after multiple steps of diagnosing, I have found that my loud humming noise has come from my wheel bearing. Basically when I turn right, the humming sound goes away. But when I turn left or go straight, the sound comes back again. Anyone know which side I need a new wheel bearing? Also...

any chance some one knows the number of a front wheel bearing of 2011 ct200h? thanks (i know, i know, dealer sells the hub but that's not what i need):)
