Chevrolet Sonic Repair Manual / Chassis / Wheels/Tires / Wheels / Lead/Pull Description

At a constant highway speed on a typical straight road, lead/pull is the amount of effort required at the steering wheel to maintain the vehicle's straight path.

Lead/pull is usually caused by the following factors:

Road slope
Variability in tire construction
Wheel alignment (front cross caster and camber)
Unbalanced steering gear
Electronic Power Steering (EPS) steering position and torque sensors not calibrated correctly, if equipped.
