1. Park the vehicle on a level ground, in an unloaded condition*, and with the wheels straight forward.

*

: Unloaded condition.....Fuel tank is full. Engine coolant and engine oil are at specified level. Spare tire, jack 

and tools are in designated position.

2. Inspect the tire pressure.

• Adjust to the recommended pressure if necessary. (See 02-50-1 SUSPENSION TECHNICAL DATA.)

3. Inspect the wheel bearing play.

• Correct if necessary. (See 03-11-2 WHEEL HUB, STEERING KNUCKLE INSPECTION.) (See 03-12-2 

WHEEL HUB COMPONENT INSPECTION.)

4. Inspect the wheel runout.

• Correct if necessary. (See 02-50-1 SUSPENSION TECHNICAL DATA.)

5. Rock the vehicle, and verify that there is no looseness in the steering wheel joint and suspension ball joint.
6. Rock the vehicle, and verify that the shock absorber operates properly.
7. Measure height H from the center of the wheel to 

the fender brim.

8. Verify that the difference between the left and 

right dimension H is within the specification.

• If it exceeds the specification, repeat the Step 

2— 7.

6. Install the shock absorber and coil spring, then tighten the mounting rubber nuts to the specified torque.

Tightening torque

46.1— 62.7 N·m {4.71— 6.39 kgf·m, 34.1— 46.2 ft·lbf}

7. Install the cowl grille. (See 09-16-11 COWL GRILLE REMOVAL/INSTALLATION.)
8. Install the windshield wiper arm. (See 09-19-3 WINDSHIELD WIPER ARM AND BLADE REMOVAL/

Total Toe-in Adjustment

1. Jack up the front of the vehicle and support it on safety stands.
2. Loosen the locknut of the tie-rod end.
3. Remove the rack boot clamp.
4. Adjust the total toe-in by rotating each tie rod (left and right) in the opposite directions by the same amount 

respectively.

Note

• Toe angle changes by approx. 6 mm {0.2 in} per one rotation of the tie rod for one wheel.

• Each tie rod has a right-hand thread. When increasing the toe-in angle, rotate the right tie rod toward the 

front of the vehicle and rotate the left tie rod toward the rear of the vehicle by the same amount.

5. Tighten the locknut of the tie-rod end.
