Caster refers to the angle of the steering pivot axis in relation to the vertical axis as viewed from the side of the vehicle. On a 2024 Ford F-250, this angle influences steering stability and directional control. It is measured in degrees and can be positive or negative. Positive caster means the steering axis tilts toward the rear of the vehicle at the top, while negative caster indicates a forward tilt.
Proper caster alignment is crucial for maintaining straight-line stability at higher speeds and for facilitating the steering wheel’s return to center after a turn. When the angle is within the manufacturer’s specified range, it contributes to reduced tire wear and improved handling. Historically, maintaining this angle has been a standard part of vehicle maintenance procedures to ensure optimal performance and safety.
