FRONT WHEEL TOE-IN
^
Inspection
1. Using a toe gauge, measure the front wheel toe-in.
Toe-in: 0 ± 3 mm (0 ± 0.12 inch)
2. Mark the rear sides of left and right tires at height corresponding to the center of spindles and measure distance "A" between marks.
3. Move the vehicle forward so that the marks line up with front sides at height corresponding to the center of spindles.
4. Measure the distance "B" between left and the right marks. Toe-in can then be obtained by the following equation:
A - B = Toe-in
^
Adjustment
1. Loosen the left and right side steering tie-rods lock nuts.
2. Turn the left and right tie rods equal amounts until the toe-in is at the specification.
Both the left and right tie-rods are right-hand threaded. To increase toe-in, turn both tie-rods clockwise equal amounts (as viewed from the
inside of the vehicle).
3. Tighten the tie-rod lock nut.
Tightening torque: 83 Nm (8.5 kgf-m, 61.5 ft. lbs.)
