Question about 2005 Chevrolet Silverado
You can have a scanner read the abs code, more than likely if you have a growling or humming noise in the Left front then a wheel bearing is bad. the abs in these trucks has the front speed sensors bolted into the wheel bearings, if the bearing gets bad it will sometimes cause the light to come on due to things like broken or "shifting" tone ring, lifted sensor (air gap) due to corrosion, etc... buying an aftermarket bearing comes with a sensor already installed and so normally will fix the problem (if the scanner says that the same sensor is causing the fault of course). check the bearing by jacking up the side of the vehicle you suspect, use a jack stand to support the truck from dropping accidentally, grab the wheel on top and bottom, one hand on each, then rock the wheel to check for play, there should be none, play could indicate a faulty bearing, or some other component. now check for roughness and noise in the bearing by placing one hand on the spring, either coil spring or torsion bar, and spin the wheel by hand, if the bearing is bad you will feel a vibration coming through the spring, you may also hear the "roar" or "hum" of the bearing when it is spinning. This will tell you if the bearing is actually at fault. if you are not comfortable doing this yourself bring it to a qualified mechanic and have them check for you, also a scanner to check the code should be done also to ensure more then one problem does not exist. hope this will help you. cheers

Good indication of something wrong from that side most likely a wheel bearing, the abs sensor is located at the bearing hub,it must have play causing improper reading for sensor,i recommend you replace the complete wheel bearing hub which includes the sensor .once your done go to auto zone or advance they can rest the light for free.
