PRE-INSPECTION
1. Check the tire inflations and set to the recommended pressure, if necessary.
2. Inspect the front wheel bearing play; replace the bearing if necessary.
3. inspect the wheel and tire runout.
4. Inspect the ball joints and steering linkage for any excessive looseness.
5. The vehicle must be on level ground and have no luggage or passenger load.
6. The difference in height between the left and right sides from the center of the wheel to the fender brim
must not exceed
10mm (0.39 in).
7. Shake the vehicle to check operation of the shock absorbers.

Adjustments
Maximum steering angle
1. Loosen the left and right tie rod locknuts, then turn the tie
rods equally.
Maximum left/right difference: 3mm (0.12 in)
2. Tighten the tie rod locknuts.
Tightening torque:
34-50 N-m (3.5-5.1 m-kg, 25-37 ft-lb)
3. Adjust the toe-in after adjusting the steering angle.
4. Inspect and adjust the toe-in after adjusting the turning angle.

Total toe-in
1. Loosen the left and right tie rod locknuts, then turn the tie
rods equally.
Caution
l The left and right tie rods are both right threaded,
so, to increase the toe-in, turn the right tie rod to-
ward the front of the vehicle and the left tie rod
equally toward the rear.
l One turn of the tie rod (both sides) changes the toe-
in by about 6mm (0.24 in).
2. Tighten the tie rod locknuts.
Tightening torque:
34-50 N-m (3.5-5.1 m-kg, 25-37 ft-lb)
