Bump steer is when the steering angle changes with suspension movement. You really won't see that on anything other than rigs with chassis mounted servos.

Picture this...the rod that goes from your chassis mounted servo arm to your knuckle is at an angle. As your suspension compresses, the rod pushes out on your knuckles causing you tires to steer to one side without the servo arm moving. A panhard bar at the same angle as your steering rod will allow the axle to swing in and arc from side to side, and get rid of the bump steer. Hope that helps a little. |
