Lamonte,
There are several questions that you need to answer to enable us to answer your question. What type of front bearing lubrication do y ou have, packed bearings or oil bath? Where is the grease leaking from? Was the brake overheated?
Without any more information, it sounds like you had an overheated brake that burned the ABS sensor, and caused oil expansion so that oil leaked out the rubber plug in the center of your hub cover. If only the inner hub seal is leaking and getting oil on the inside of the tire and on the brakes, that should not turn on the ABS light. If only the hub cover is leaking on the outside of the tire, this will not get oil on the brakes or turn on the ABS light.
