When the steering axis is tilted forward over suspension, what is this condition called?

• A. Positive Caster
• B. Negative Caster
• C. Camber
• D. Toe

Answer: (B)

Negative caster is the name for a steering axis that tilts forward at the top, toward the front of the vehicle. When the steering axis leans forward over the suspension like that, the wheel is said to have negative caster. This sign convention means the steering axis crosses the ground ahead of the contact patch, which reduces straight-line stability and self-centering, and often makes steering lighter but less stable at speed. Camber and toe describe different things—camber is the vertical tilt of the wheel, and toe is the horizontal angle of the wheels relative to the vehicle’s centerline—so they’re not describing the steering axis tilt.
