One of the front wheel bearings is bad and you will need to replace the entire hub assembly. Also, you will need a 30mm axle nut to remove the hub off from the shaft.

    30mm fits well enough. rent a 30mm deep well socket for free from advance auto if you have one nearby. remove caliper. remove (3) 15mm nuts to free the bearing assembly. gently hammer the axle inward and not so gently hammer the hub/bearing free. solved my girlfriend's loud humming 2004 ion. the bad bearing was the one that made more noise when we unloaded it (turn the car in the direction of the bad bearing)

    *easier to remove the 15mm nuts if you can turn the wheel to get better access

POOR GAS MILEAGE


Have you changed the fuel filter? I know it sounds weird but a plugged filter will make a truck use more gas. The computer tries to compensate for less fuel by commanding the injectors to open longer. Also a plugged filter will cause excess back pressure on the fuel pump making it loud.. Good Luck.

The one thing you did not mention that I needed to do to remove the Hum was 4 wheel alignment. Smooth and quiet now. Hope that helps and have a great day.
