ACKERMAN

What:  Ackerman is the measurement of the difference in turning angles made by two front wheels when a vehicle is making a turn.  The wheels have to take different angles in a turn because the outside wheel in the turn has to travel farther in the turn than the inside wheel.

How: Setting the correct angles on the steering arms where they connect to the steering linkage creates correct Ackerman angles.  Stock vehicles have this calculated in the original design but when different suspensions, altered wheelbases or steering arms are bent to clear when installing a dropped axle this measurement needs to be checked and adjusted.
