engine noise on 2002 Chevrolet Tahoe

what would cause a high pitched squeal when accelerating?

Asked by for the 2002 Chevrolet Tahoe
This is typically caused by glazed/slipping drive belts. Have your belts and tensioners checked for wear and proper operation. There also may be something leaking on your belts, like coolant, which will make them squeal.

a high pitched squeal under hard accel or aggresive driving can be caused by a timid spouse. try driving without her. (just kidding) dandd is most likely right.
also check ur wheel bearings( raise the car and check if the wheels wiggle or have "play" from the hub)
