Envoy 2WD V6-4.3L VIN W (1998)
Linear sum toe-in exists when the distance between the front wheels is less at the front of the axle than at the rear of the axle.
Angular toe-in exists when the front wheel center line is not parallel to the forward projected vehicle center line.
The actual amount of toe-in is normally a fraction of a degree. Toe-in is measured from the center of the tire treads or from the inboard side of the tires
. The purpose of toe-in is to assure parallel rolling of the front wheels, and to offset small deflections of the wheel support system during forward
motion. Incorrect toe-in results in excessive toe-in and unstable steering. Toe-in is the last alignment procedure to be set in front wheel alignment.
