±±±±
3 mm (0
±±±±
0.12 in)
1) Set the toe-in gauge to rear sides of right and left
front tires at height corresponding to center of spin-
dle.
2) Mark each right and left tires at height corre-
sponding to center of spindle and measure the dis-
tance “A” between marks.
3) Move the vehicle forward to rotate wheels 180
°
.
NOTE:
Whenever rotating the wheels, drive the vehicle for-
ward.
4) Measure the distance “B” between right and left
marks. Toe-in can then be obtained by the follow-
ing equation:
A
−−−−
B = Toe-in
• Adjustment
1) Make sure that the right and left steering angles
are within specified value.
2) Loosen the right and left side steering tie-rods
lock nuts.
3) Turn the right and left tie rods equal amounts un-
til the toe-in is at the specification.
Both the right and left tie-rods are right-hand
threaded. To increase toe-in, turn both tie-rods
clockwise equal amounts (as viewed from inside of
the vehicle).
4) Tighten the tie-rod lock nut.
Tightening torque:
