Key Components of Wheel Alignment
The key components of wheel alignment include toe, camber, and caster angles, which are essential for ensuring proper tire contact, even wear, and optimal vehicle stability and performance.
4.1 Toe Alignment

Toe alignment refers to the direction in which the front wheels of a vehicle point, measured as the difference between the distances of the front and rear edges of the tires. Proper toe alignment ensures even tire wear and straight-line stability. Incorrect toe settings can lead to uneven tire wear, reduced fuel efficiency, and poor handling. Toe alignment is typically measured in inches or millimeters and can be set to toe-in (wheels point slightly inward) or toe-out (wheels point slightly outward). Manufacturer specifications vary by vehicle, so it’s crucial to follow the recommended settings. Adjusting toe alignment requires precise tools and is often part of routine wheel alignment services. Misaligned toe can cause pulling to one side while driving, making it essential to address promptly for optimal vehicle performance and safety.
4.2 Camber Alignment

Camber alignment refers to the tilt of a vehicle’s wheels, measured as the angle between the wheel and the vertical plane. Proper camber ensures even tire wear and optimal handling. Positive camber means the wheel tilts outward at the top, while negative camber means it tilts inward. Incorrect camber alignment can lead to uneven tire wear, reduced traction, and poor vehicle stability. Manufacturer specifications vary by vehicle, so it’s essential to follow recommended settings. Adjusting camber often requires modifying suspension components or using specialized tools. Misaligned camber can cause pulling to one side or reduced cornering performance. Regular checks are crucial to maintain proper camber alignment, especially after modifications or collisions.
