Front bump steer is the steering movement of the front wheels as a result of vertical travel without input from the steering wheel. A requirement for automotive front suspension usually is defined as “as little bump steer as possible” in order to avoid unpredictable vehicle behavior on rough surfaces and also to increase the lifespan of the tire. The aim of this study is support this development without the usage of kinematics software or at least reduce the time spent in the software, since many people does not have access to this engineering tool. Therefore a mathematical model based on 2D kinematics model was developed with the purpose to determine the location of the tie rod inner hardpoint, once that the main suspension geometry parameters was defined (caster, camber, scrub radios, caster offset and Ackerman angle).
