Caster on a wheel alignment or spooring
Second is CASTER, axial tilt swivel caster is steering towards vertical line when viewed from the side of the car. In this caster Also there are two kinds of positive caster and the caster is the negative caster, for the positive caster is when the wheel is tilted backward when viewed from the side. And the opposite when the wheels tilt toward the front when viewed from the side, the so-called negative caster. If the caster is too positive, the effect is when turning the steering wheel becomes heavier and noticeably shaking. If the caster is too negative then the wheel will become unstable and was floating then physically tire will look bumpy and uneven wear. Then, when the position of left and right wheels caster not equal or balanced car will tend to pull to one side only, then when the brake then there will be symptoms tends to pull to one side only.For more information, you can visit toolbox casters.
Wheel camber angle
Third is the camber, camber is a tilt angle of the wheel to the vertical when viewed from the front of the car. Just like before, there are two kinds of camber is negative camber and positive camber. For the negative camber is the tilt wheel when viewed from the front car tends towards the inside of the car. And the opposite is when viewed from the front-wheel drive car is more likely skewed to the outside of the car. For obvious when the negative camber tendency of the wheel would form a V and for positive camber wheel will tend range to form the letters A, all of the which when viewed from the front of the car. When it is unknown how many degrees of tilt then the next is in setting the balance between the left and right front wheels so that the steering will be more stable and lightweight. and Also will avoid uneven wear and tear on the tires. The effect when the camber is too positive is the steering will be too soft and the tires wear unevenly only the outside only, then when the camber is too negative then the wheel will be heavier and tires tend to wear on the inside only, other effects are wheel vibration tasted great and wheel bearings will wear faster so that the car will tend to throw to one side.
