The wheel alignment refers to the angular relationship between the wheels, the suspension attaching parts, and the ground. To achieve the desired handling characteristics of a vehicle under various operating conditions, modern steering geometry relates to both the front and the rear suspension systems. It must also be realized, that the various measurable angles that can be checked while the vehicle is stationary is not a real indication of the changes that occur in a dynamic situation.

Even though some of the following descriptions may not be adjustable, each is an inherent part of the vehicle's suspension tuning.

Adjust the wheel alignment specifications in the following order:

  1. Front caster
  2. Front camber
  3. Front toe

Perform a complete wheel alignment check when a service check is necessary. This check includes the measurement of all four wheels. When the vehicle is geometrically aligned, fuel economy, tire life, and steering performance are increased.
