Toe-Out-on-Turns (TOOT)
Toe-out-on-turns is another diagnostic
measurement that is valuable in troubleshooting
steering and handling problems.
TOOT or Turning Radius, as it is also known,
is the difference in the turning angle between
the inside and the outside wheel.
NOTE: The Aligner vehicle database does not
contain specifications for
toe-out-on-turns.
Refer to an alignment specification book or
the vehicle’s shop manual.
1. After completing the Caster/SAI measurement
on one side, continue to turn the wheel past
10
o
. The software senses this and places a
red status bar over the TOOT icon.
2. Follow the arrow to a 20
o turn. Once again, the
cursor ball turns from red to yellow to green
as the angle is approached.
3. When the stop sign appears
, hold the wheel
steady until the green box/depressed icon
appears and the stop sign disappears,
indicating completion of the measurement.
4. To measure toe-out-on-turns on the other side,
turn the wheel the opposite direction. Note
that the status bar appears over the caster/
SAI icon first. It is always required to measure
caster/SAI before TOOT.
5. Turn to the Caster/SAI position. When
completed, the red status bar appears over
the toe-out-on-turns icon. Continue the turn
to the TOOT position.
6. When complete, the software then places a
red bar over the center steering icon. Follow
the arrow to the center until the stop sign
appears, Follow the arrow to the center
until the stop sign appears, making sure the
number displayed on the steering wheel in the
center of the screen is between -0.2 and +0.2.
Then step out of the way so targets and pods
see each other, and wait for the alignment
readings screen to appear. To view toe-out-
on-turns values, advance to the
All Readings
screen.
