CASTER ADJUSTMENT



Caster is the measured angle between a true vertical line passing through the center of the wheel and a line drawn through the center of the upper and lower ball joints.

CAMBER ADJUSTMENT



Camber is the measurement in degrees of the outward or inward tilt of the top of the wheel and tire in relation to the true vertical. Tilting of the top of the tire away from the centerline of the vehicle is called positive camber. Tilting toward the vehicle centerline is negative camber.

TOE-IN ADJUSTMENT



Toe-in is the measurement in inches of the inward departure of the front of the wheels from a line drawn through the horizontal center of the wheel, parallel to the centerline of the vehicle. Toe-in is expressed as the difference in measurement between the extreme front of the wheel pair and the extreme rear of the wheel pair.

If a tram gauge is available, position the front wheels straight-ahead. Loosen the tie-rod clamp on one end and adjust the one rod to the total specified toe-in. Loosen the other tie-rod clamp and rotate both rods the same amount in the same direction to put the steering gear on high point and the wheel positioned straight-ahead. Secure the inner tie-rod clamps with the bolts down and horizontal. Secure the outer bolts vertical and to the rear.
