Toe Setting: The toe setting represents different
distances between the front and rear of the tires
(measured at the vertical center line of the tires).
• Toe-in occurs when the tire front distance is
less than the tire rear distance.
• Toe-out occurs when the tire front distance is
greater than the tire rear distance.
Wheels are generally set with initial toe-in. As
the vehicle operates tires tend toward a toe-out
condition. By starting with an initial toe-in set-
ting, a desirable “near zero toe-in” can be
achieved when the vehicle is in motion.
Incorrect toe settings, where toed-in or toed-
out, can have a significant affect on tire wear. The
toe setting is adjusted by lengthening or shorten-
ing the cross tube.
Caster Adjustments:
Caster is the fore and aft tilt (toward the front or rear of the motorhome) of
the steering kingpin as viewed from the side of the motorhome.
• “Positive” caster is the tilt of the top end of the kingpin toward the rear of
the motorhome.
• “Negative” caster is the tilt of the top end of the king-
pin toward the front of the motorhome.
A caster angle more positive than specified may result
in excessive steering effort and/or shimmy. An angle less
positive may result in vehicle wander or poor steering
return to center. The caster angle is determined by the
installed position of the steer axle.
