I have a 2005 heavy duty 2500 5.9, 112000 m. Just installed front hub bearings myself everything fine for a few hundred miles, started to here a howling noise at low speeds . CLutch in or out, A few hundred more miles I here it all the time.

Did you pack the bearing before installing it?
Did you torque it down then back it of an 1/8 of a turn?

Another possibility: You've become so accustom to your trucks sound with a bad bear... Now that you fixed it, the sound of your tires are now prevalent.
