Which statement best describes camber, toe, and caster in suspension geometry?

• A. They are engine timing parameters.
• B. They are wheel alignment angles.
• C. They are types of suspension springs.
• D. They are steering wheel controls.

Answer: (B)

These three terms describe wheel alignment angles that define how the wheel is positioned in relation to the vehicle and how the steering axis is oriented. Camber is the tilt of the wheel in the vertical plane when viewed from the front; it affects how evenly the tire wears across the tread and how the tire grips during cornering. Toe is the angle of the wheels in the horizontal plane relative to the vehicle’s centerline; toe-in helps with straight-line stability but excessive toe-in or toe-out can cause uneven tire wear and alter handling. Caster is the tilt of the steering axis in the longitudinal plane; positive caster provides self-centering and stable steering, while too little can make steering feel light and wandering, and too much can increase steering effort.

Together, adjusting camber, toe, and caster tunes how the wheels contact the road, how the vehicle tracks straight, and how tires wear over time. These are wheel alignment angles, not engine timing parameters, suspension spring types, or steering wheel controls.
