Humming Issue

I have a 98 cavalier that has what was almost 100% sure to be a bad wheel bearing... all of the sounds and normal signs... so the drivers side front was replaced and yes it was very bad... passenger side front checked out fine... new rotors, pads .... well sounds still there, in the front.... I'm pretty sure it's not suspension related anymore because the sound varys on engine rpms not speed.... now I'm kind of stumped... usually I can figure this stuff out but I'm running a blank.. any ideas?

is there any kind of steering irregularity like pulling left or right..?

nope, drives perfect down the road..... car has new tires too

i don't know too much...

but i would check all belts and fans see if any are loose or if the fan is off center or something

is there any kind of vibration or just an audible hum?
