WHEELS/TIRES 11-5

Wheel A lignment

Toe-in is the amount that the front wheels are closer to-

gether 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 in the figure. 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 chalk 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 s traight 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.) at 1G

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.
