Single Wheel Positioning
The vehicle can be jacked to allow each wheel
to be compensated independently. This is
useful if a wheel must be removed during the
alignment, for example to install a shim in the
rear. The
Single Wheel Positioning procedure
locates each wheels axis of rotation by
jacking the vehicle and moving each pod and
target.
1. Select Single Wheel Positioning from the Measure
screen. The screen shows the vehicle’s 4 wheels
with a red box around the left front wheel. If a
check appears in the box, it indicates that the
wheel has been previously successfully positioned.
Use the up/down arrow keys or mouse to place the
box around the wheel to be positioned and press/
click OK. You can also double-click on the desired
wheel.
2. Raise the front or rear axle being positioned as
instructed. Notice that VODI, shows which wheel
has been selected.
3. Following the on-screen graphics, rotate the pod
or target back approximately as directed by the
indicator.
4. When complete, an instruction screen appears
reminding you to lower the vehicle. This is
only necessary when all wheels that need to
be positioned individually have been done. It
is acceptable to leave the vehicle elevated if
additional wheels require compensating. Lower
the vehicle and jounce the suspension prior to
returning to any readings screen.
5. As each wheel compensation is completed the
software returns to the selection screen and a
check mark appears next to the wheels that have
been successfully positioned. Click on the Cancel
button once all wheels are compensated to return
to the alignment readings screens.
NOTE: See pages 33-35 for more information
on wheel runout compensation.
