Lead/Pull Description

/ 9-5 (9650) / 2011 / 7. Suspension, wheels / Wheels and tyres / Technical description / 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 straight path.

Note

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
