I suspect you have some loose or worn belts. Check the wear and tension, adjust and/or replace them. Probably the power steering belt. John In Montana
Answermost likely that first answer is correct. In the morning, your alternator needs more energy to charge the battery up from sitting over night. So it takes more power to turn the alternator, putting more stress on the belt, causing a loose or worn one to squeal until the battery is near or at full charge. just try getting the drive belts tightened, if that doesnt work, get new ones on.Related Questions

Start with the most likely andeasiest to fix. Check your brake pads... There is a wear indicator on the inside pads (closest to engine) that will rub on the rotor and make a squealing noise to warn you that the pads are getting thin.
