Alignment caster, camber, and toe are three critical angles adjusted during the wheel alignment process to ensure optimal vehicle performance, handling, and tire wear. Here's a breakdown of each angle:

1. Caster:

   • Definition: Caster refers to the angle of the steering axis when viewed from the side of the vehicle. It is the angle between the vertical axis of the wheel and the steering axis.
   • Purpose: Caster affects steering stability, steering effort, and returnability. Positive caster, where the steering axis leans toward the rear of the vehicle, enhances stability and straight-line tracking.

2. Camber:

   • Definition: Camber is the angle of the wheel concerning the vertical axis when viewed from the front or rear of the vehicle. It can be positive, negative, or neutral.
   • Purpose: Camber affects tire wear and cornering performance. Proper camber ensures even tire contact with the road surface, promoting balanced wear and optimal traction during cornering.

3. Toe:

   • Definition: Toe is the angle at which the wheels point concerning the centerline of the vehicle when viewed from above. It can be toe-in or toe-out.
   • Purpose: Toe alignment affects steering response, tire wear, and straight-line stability. Correct toe alignment ensures that the wheels roll parallel to each other and in line with the vehicle's direction of travel.

Importance:

• Proper alignment of caster, camber, and toe angles optimizes tire wear, vehicle handling, and fuel efficiency.
•  
• Misaligned angles can lead to uneven tire wear, reduced steering response, and compromised safety.
