Default Grinding/humming sound...NOT wheel bearing???

That'* right. I have an all-time humming/growling sound coming from the driver'* side front that has been steadily getting louder. It doesn't matter if I turn the wheels, the sound remains the same. I just spent a few hours replacing the wheel hub/bearing.

Went out for a test drive...same sound. Could it be the half shaft? Please don't say differential....

Thanks for any advice/help.

Check the strut tower bearing, drive over a speed bump steering wheel straight then left and right. Does the noise increase?
The diff is on the passenger side so I think your ok?

I suppose there is no chance that it could be your pneumatic self-leveling pump running? Hmmm?

Having noise from same driverside front wheel. Can hear a lot
at low speed like parking.

Today I took my car to the dealer & they adv the problem was a bad hub.
So they replaced the bearing assmbly & hit me for $468.

So tonight parking the car at walgreens I hear the noise on the passenger side
& turned the radio down & heard it on driverside.

& now that I hear on both sides I'm not sure what it is.............

Nono, it'* a constant whirring just like a bad wheel bearing, but I replaced it, and it'* still doing it. I guess my question is what is the next bearing in the drivetrain that would be growling like that?

Let me add to this since the last message was from my cell phone. :P

It'* a constant whirring that increases in volume and pitch as I increase speed, then decreases in volume and pitch as I decrease speed, just like a bad wheel bearing.

However, I replaced the wheel bearing, and it'* still doing it. Would the passenger side wheel bearing telegraph over to the driver'* side? I wouldn't think so.

Would the differential make a growling bearing noise if it was going bad?

Anyone know where I can find an exploded view of the drivetrain on the driver'* side, perhaps?
