FRONT WHEEL TOE READING
Toe: The difference in distance between the front and rear of the front wheels
Toe-in: Distance between front of wheels is less than distance between rear of wheels
Toe-out: Distance between front of wheels is greater than distance between rear of wheels
Adjust Laser Beam Mirror & Target:
The Left Laser Toe Gauge projects a laser beam onto
the right mirror (A). This beam is reflected back to the
graduated toe scale on the Left Laser Toe Gauge.(See
Fig. 29)
Adjust the laser beam vertically to the center of the
mirror (A) by using the knob (E) on the Left Laser
Toe Gauge. Rotate the laser beam assembly inside the
tube of the Left Laser Toe Gauge. Re-tighten knob.
If the laser beam, reflected back from the mirror (A),
doesn’t strike the graduated toe scale, loosen both
knobs (R) on the Right Laser Toe Gauge (See Fig.
30). Rotate the mirror housing (A) until the laser beam
image strikes the graduated toe scale. Re-tighten both
knobs.
Reading Front Wheel Toe:
Read Front Wheel Toe on the graduated toe scale on
the Left Laser Toe Gauge. (See Fig. 31)
Toe is within spec if the laser beam image is in the
center of the scale at zero.
One-half of the manufacturer’s total toe specification is already dialed in with each of the magnets,
so a reading of zero on these scales means the toe is correctly adjusted to the manufacturer’s
specification.
