Abs & AdvanceTrac Light On

vakladder_78

I recently bought a 2003 Ford Expedition 5.4 L Eddie Baur w/ 95,000 miles on it. It has been driving great for the 1 1/2 months but a few days ago the ABS and AdvanceTrac light came on. The truck makes a growling/grinding noise while turning left at all speeds and occasionally feels like the front brakes are grabbing when I take off from a stopped position. Also, there is some sort of rubbing/grinding noise in the rear. Please any input or suggestions would be great before I take it to a garage. Thanks!!!

Is it doing this in both 2WD and A4WD? Sounds like a sensor may be bad and causing the system to kick into 4WD. The A4WD system uses speed sensors that are also used in the ABS and AdvaceTrac systems.
