Left Front Mechanical Noise while driving over 35 mph? on 2003 Cadillac DeVille

Problem occurs each time I drive. Sound resembles a small motor running it gets louder the faster I go and subsides as I slow down.

Sounds like a failing wheel bearing. As you go faster, probably sounds like a single-prop plane flying next to you. Replace the wheel bearing and the noise should be gone. Here it is wheel bearing/hub assembly: http://www.autozone.com/autozone/parts/Duralast-Wheel-Bearing-Hub-Assembly-Front/2003-Cadillac-Deville/_/N-jk2aqZ6o2ny?itemIdentifier=972637_453633_0_
