What is Wheel Alignment


The vehicle must have proper straightline performance for stable driving, cornering performance for driving around curves, recovery force for returning to the straight-line condition, the capacity to soften the shock transmitted to the suspension when the tires are impacted, etc. Therefore, the wheels of a vehicle are mounted at specific angles to the ground and specific suspensions for each purpose. This is called wheel alignment. The wheel alignment has the following five factors:

  • Camber
  • Caster
  • Steering axis inclination (kingpin inclination)
  • Toe (toe-angle, toe-in and toe-out)
  • Turning radius (wheel angle, turning angle) If even one of these elements is incorrect, the following problems can occur:
  • Difficult steering
  • Poor steering stability
  • Poor recovery on curves
  • Shortened tire life
