Note
•  Unloaded vehicle: Fuel tank is full. Engine coolant and engine oil are at specified level. Jack and tools are in designated position.
•  Difference between the left and right dimension for camber is within 30′.
•  Difference between the left and right dimension for caster is within 45′.

Maximum Steering Angle Adjustment

1.  Remove the cap.

2.  Loosen the adjusting bolt locknut.

3.  Turn the adjusting bolt to provide the correct turning angle.

Standard steering angle
Inner: 31°30′—35°30′
Outer: 27°00′—32°00′

4.  After adjustment, tighten the locknut to the specified torque.

5.  Install the cap.


Caster and Camber Adjustment

1.  Loosen the upper arm shaft bolt and insert or remove adjustment shims to provide the correct angle.

Note
•  Shims No.1—5 are used on either side. Do not use more than two.
•  Shims No.6—11 are used at the front and rear of either sides. Do not use more than one.
Caution
•  Use the genuine shims to prevent looseness of the upper arm bolt. The total thickness of the shims should not exceed 12 mm {0.47 in}.
Note
•  Camber (Shims No.1—5): A change of shim thickness of 1 mm {0.039 in} results as follows:

2.  After adjustment, tighten the upper arm shaft bolt to the specified torque.

Tightening torque
150—172 N·m {15.3—17.5 kgf·m, 111—126 ft·lbf}

3.  Confirm the front wheel alignment as in the specification.

•  If not within the specification, adjust the front wheel alignment again.


Total Toe-in Adjustment

1.  Loosen the tie-rod end locknuts.

2.  Turn the tie rods by the same amount in the opposite direction.

Total Toe-in Standard
3—9 mm {0.12—0.35 in}
Note
•  One turn of the tie rod (both sides) changes the toe-in by about 30 mm {1.18 in}.
•  The left and right tie rods are both right threaded, to increase the toe-in, turn the right tie rod toward the front of the vehicle and the left tie rod equally toward the rear.

3.  Tighten the tie-rod end locknuts.
