A CENTERLINE alignment is a basic alignment procedure where the front wheel TOE is adjusted to the center line of the vehicle.   Essentially, the position of the rear wheels is not considered.  This alignment type corrects all front wheel alignment angles, but the rear wheels may not track correctly behind the front wheels, resulting in DOG-TRACKING and a mis-aligned steering wheel.

Other alignment types are THRUSTLINE Alignment and 4-WHEEL Alignment.
