just because its putting out an ac voltage doesn't mean its good. test the resistance of the hub, hook one probe from your multimeter to one wire, and the other one to the other wire. if it is over 1.5 M ohms its probably going bad. give me until tomorow when i go to work i'll look up the wiring diagram and post the colors for you. if you can give me either the exact code number or what the code says that will help a lot. also the noise your hearing over bumps is more than likely the upper part of the struts, gm has a tsb out about them. i'll try to post that as well.
