Rubbing or grinding soud front driver side area

SOURCE: 2004 stx f150 right front wheel grinding noise,

I agree with duane_wong on this one ( not like he was looking for my approval :) ), it sounds like a problem with the IWE ( Integrated Wheel End ) on that side.
Quick test, when you are in 4H ( or 4L ) does the noise still happen ?
I would say cracked vacuum line to the IWE, or a problem with the vacuum diaphragm in the IWE. You can test by having the motor running in park, and in 2H, and check the vacuum line at the IWE for vacuum. Make sure you test to the vacuum line, not the vent line ( ends in the engine compartment, not hooked to anything )

This is a block diagram of the IWE vacuum system

Testimonial: "great help!"

SOURCE: 1998 Ford Mondeo GLX, loud humming sound, front driver side.

Most likely it's a wheel bearing going out.., If you turn to the right, or the left when driving the noise will change pitch. Been there done that.....

SOURCE: Rubbing or grinding noise coming from Driver side rear tire/wheel

I had the same problem that based on interner research is common for Fords trcuks/suvs. The common problem fro rear humming "rubbing"sound might be the rear wheel bearings/seal. These will need to be replaced as it will progressivly get worse and the noise louder and eventually the bearings can sieze. I would hesitate to take to a ford dealer if I were you as it can run $500-900. Take to mechanic that knows how to replace wheel bearings and seals. My mechanic replaced them for about $150. and the bearing and seals are around $40. A good way to test this is to raise the wheel were you can freely spin by hand...if does not spin or there is a lot of friction then it might be the wheel bearings.
Good Luck
