Refers to changes in wheel alignment (toe, camber and caster) as the wheel moves through the suspension range. Wheel alignment is set with the car stationary, so bump steer affects must be properly considered to ensure that suspension movement does not cause adverse changes in handling or grip.
Tendency of a vehicle to momentarily steer off-course when a wheel strikes a road bump.
The ill-effect a fully compressed damper has on steering through turns. Referred to as such because often times when a damper is fully compressed, it is against its bump stop. When this point is reached, neither the damper nor the spring can do it's job, usually causing loss of grip. May also refer to when the wheels steer themselves, without input from the driver, caused by bumps in the track interacting with improper suspension tuning or alignment.
A directional change in steering caused by road surface irregularities. As the suspension moves through jounce and rebound, changes in alignment at the front or rear wheels may alter the vehicle's path.
can be caused by a number of alignment related issues. This is when a vehicle darts or wanders, especially when operated on a less than ideal driving surface. In other words, it takes a concentrated effort to keep the vehicle in a straight line. Body roll... is most noticeable when turning at speed. One side of the suspension compresses and the opposite side lifts. Camber angle – A steering geometry term; see diagram. Camber is impacted the greatest when lifting a Ford with TTB suspension. Caster Angle – A steering geometry term; see diagram. Caster is impacted the greatest when lifting a vehicle that has radius arms.
The tendency of a vehicle to suddenly veer or swerve to one side when hitting a bump or dip in the road. The condition is caused by uneven toe changes that occur as a result of the steering linkage or rack not being parallel with the road surface. This ca
Bump Steer is the term for the tendency of a wheel to steer as it moves upwards into jounce. It is measured in degrees per metre, or degrees per foot, typically.
