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 motorhome operates tires tend toward

a toe-out condition. By starting with an initial

toe-in setting, a desirable "near zero toe-in" can

be achieved when the motorhome is in motion.

Incorrect toe settings, where toed-in or toed-

out, can have a signiﬁ cant affect on tire wear.

The toe setting is adjusted by lengthening or

shortening 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 kingpin toward the front of the motorhome.

Setting the caster angle more positive than

speciﬁ ed may result in excess steering effort

and/or shimmy. Decreasing the angle may result

in the motorhome wandering or poor steering

return to center. The caster angle is determined

by the installed position of the steer axle.
