Pacifica V6-3.8L (2008)
Steering axis inclination (1) is the angle between a true vertical line starting at the center of the tire at the road contact point and a line drawn through the
center of the upper ball joint (or strut) and the lower ball joint. S.A.I. is built into the vehicle and is not an adjustable angle. If S.A.I. is not within
specifications, a bent or damaged suspension component may be the cause.
INCLUDED ANGLE (I. A.)
Included angle (3) is the sum of the S.A.I. (1) angle plus or minus the camber (2) angle, depending on whether or not the wheel has positive or negative
camber. If camber is positive, add the camber angle to the S.A.I. angle. If camber is negative, subtract the camber angle from the S.A.I. angle. Included
angle is not adjustable, but can be used to diagnose a frame misalignment or bent suspension component (spindle, strut).
