Drive Train Axles Bearings problem
2004 Chevy Suburban V8 Four Wheel Drive Automatic 104000 miles

I have been hearing a noise in my front end recently. It is not a loud or grinding sound but more of a subtle rubbing sound. I hear it with or with out the transmission engaged and with or without the engine running (ie, i have rolled to a stop after disengaging engine and tranmission). The noise does not change when braking but does increase a little during turns.

possible wheel bearing or tires cupped
