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.
