Chevrolet Sonic Repair Manual: 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.
Important:
Vehicles will tend to lead/pull in the direction of the road slope as part of normal operation.
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.
