8.11 Front axle adjustment
The procedure for adjusting the front axle can be obtained by selecting "Total adjustment" or
"Adjustment of front axle only" on the test page (see para. 8.8 page 30) and performing the
operations for the preparation of adjustment(see para. 8.9 page 31).
The recommended sequence of the angles to be adjusted is: CASTER – CAMBER – TOE-IN.
IMPORTANT:
Once the caster values have been adjusted, or if these are not adjusted and are taken
to be correct, it is best to "freeze" the above values. Such procedure prevents the caster values from
changing if the sensors are accidentally moved.
To do this, the measurement selection red frame (see Figure 37) must be moved to caster values and
the centre key of the front sensor must be pressed; a grid will appear above the caster values to
indicate these have been "frozen".
It is also possible to proceed so the caster values are already frozen by entering this phase,
selecting "YES" in the "automatic caster freezing" option of the "general parameters" menu (see
Figure 17). To “unfreeze”, proceed as indicated above.
Note. If the selection frame is moved to the camber values and the central sensor key is pressed, the
camber values will be frozen.
If on the other hand, the frame is moved to toe-in values and the central sensor key is pressed, the
"Jack Hold" procedure will be accessed (adjustment with wheels lifted) of the front axle only.
Makes the adjustments in the following order:
•
Casters - Front wheel cambers - Front semi-toe in
