10-4 WHEELS/TIRES
Wheel Alignment
Toe-in is the amount that the front wheels are closer
together in front than at the rear at the axle height. When
there is toe-in, the distance A (Rear) is greater than B
(Front) as shown. The purpose of toe-in is to prevent the
front wheels from getting out of parallel at any time, and
to prevent any slipping or scuffing action between the tires
and the ground. If toe-in is incorrect, the front wheels will
be dragged along the ground, scuffing and wearing the
tread knobs.
Caster and camber are built-in and require no adjustment.
A (Rear) - B (Front) = Amount of Toe-in
(Distance A and B are measured at hub height)
Toe-in Adjustment
•
Lift the front wheels off the ground.
•
Apply a heavy coat of chalk near the center of the front
tires.
•
Using a needle nose scriber, make a thin mark near the
center of the c halk coating while turning the wheel.
•
Set the wheels so that the marks on the tires are at the
front side and at the level of the axle height.
•
Ground the front wheels.
•
Set the steering wheel straight ahead.
•
At the level of the axle height, measure the distance be-
tween the scribed lines with a measure.
•
Move the vehicle rearward until the marks on the front
tires are at the rear side and at the same level as the axle.
•
Measure the distance between the scribed lines.
•
Subtract the measurement of the front from the measure-
ment of the rear to get the toe-in.
Toe-in of Front Wheels
Standard: 0 ∼ 20 mm (0 ∼ 0.79 in.)
If the toe-in is not the specified value, perform the follow-
ing procedure.
•
Loosen the locknuts [A] on each tie-rod and turn the ad-
justing rods [B] the same number of turns and the same
direction on both sides to achieve the specified toe-in.
