The primary function of caster in a vehicle's suspension system is to provide stability and steering control. Caster refers to the angle at which the steering axis is tilted from the vertical when viewed from the side of the vehicle. It is typically measured in degrees.

Here are the steps to understand the primary function of caster in a vehicle's suspension system:

1. Caster angle: The caster angle is the angle formed by a line drawn through the upper and lower ball joints of the steering axis and a vertical line. It is usually positive, meaning the top of the steering axis is tilted towards the rear of the vehicle.

2. Stability: Caster plays a crucial role in providing stability to the vehicle. When the caster angle is properly set, it helps the vehicle to self-center and maintain a straight line while driving. This stability is especially important during high-speed maneuvers and when encountering road irregularities.

3. Steering control: Caster also affects the vehicle's steering control. A higher positive caster angle enhances the vehicle's straight-line stability and improves steering returnability. It helps the wheels to maintain better contact with the road surface, resulting in improved handling and responsiveness.

4. Cornering stability: Caster angle influences the vehicle's cornering stability. It helps to resist the tendency of the wheels to wander or veer off course during turns. A properly set caster angle ensures that the vehicle tracks smoothly through corners and maintains stability.

5. Tire wear: Caster angle also affects tire wear. Improper caster alignment can cause uneven tire wear, particularly on the front tires. Excessive positive or negative caster can lead to accelerated wear on the inner or outer edges of the tires, respectively.

In summary, the primary function of caster in a vehicle's suspension system is to provide stability, steering control, and cornering stability. It helps the vehicle to maintain a straight line, improves handling, and ensures even tire wear.
