The differences between the right and left camber and caster and the relative tolerances are also displayed
in small font, as are the partial and total toe-in if not already displayed in large font.
The display of the partial toe-in allows adjusting the toe-in of vehicles equipped with a suspension system
that allows adjusting the two wheels independently; this is true for most cars. Vice versa, the display of the
total toe-in and the steering angle allows adjusting vehicles equipped with a total toe-in adjustment bar,
which does not allow adjusting the two wheels independently; this is true for all trucks and some off-road
vehicles.
Displaying the 2 axles simultaneously allows you to adjust the 2 vehicle axles at the same time from one page,
thus checking the trend of the angles during adjustment.
Adjust in order the caster, camber and toe-in of the wheels until the indicator is in the green zone
For optimal adjustment follow the adjustment order: caster, camber, toe-in.
From the Front Adjustment page you can go to the Steering page.
In the case of the truck procedure, if you wish to execute steering, you need to access it from this page.
In the case of the car procedure, it is advisable to repeat steering as a check if the caster is adjusted, since
the caster measurement displayed on this page is necessarily an estimate.
Adjustment sequence for the truck procedure:
Centre the steering box by turning the steering wheel 1.
If nec 2. essary, straighten the steering wheel by acting on the adjuster between the steering box and the steeri ng
wheel without moving the steering box
Lock the steering wheel with the steering lock 3.
Adjust underneath the vehicle to bring the total toe-in into tolerance and the steering angle to null 4.
If it is diffi cult to access the adjustment points, for example, because the vehicle is on the ground or the
adjustment point is hidden by parts of the suspension, you can use the "freezing" procedure to adjust with
the vehicle lifted or the wheels steered.
To make it easier to identify the adjustment points, use the adjustment help images.
: Freezing see paragraph 9.7
: Displays the adjustment help images see paragraph 5.1
: Switches the display from partial toe-in to total toe-in or shows the front and rear axle
simultaneously
: Goes back to the steering procedure see paragraph 7
