If the steering axis inclination is not within the specified value, after the camber and caster have been correctly adjusted, re-check the steering knuckle and front wheel for bearing or looseness.

1. Loosen the upper suspension arm set bolts.
2. Adjust the camber and caster by adding or removing shims (See  c).

   Shim thickness: 

   SHIM THICKNESS SPECIFICATIONS
   
   

   4.0 mm (0.157 in.)

   1.6 mm (0.063 in.)

   1.2 mm (0.047 in.)

   NOTE:

   Try to adjust the camber and caster to the center of the specified values.

3. How to read adjustment chart.
   1. Find the wheel alignment standard value applicable for the particular model (See SPECIFICATIONS & PROCEDURES ).
   2. Mark the selected standard value on the adjustment chart.

      Example:

      Camber: 0°00

      Caster: 0°30' (0.5°)

   3. Mark the alignment value measured when the vehicle was non-loaded on the adjustment chart.

      Example:

      Camber: 0°00'

      Caster: 1°48' (1.8°)

   4. As shown in Fig 4, read the distance from the measured value to the standard value, and adjust the front and/or rear shim thickness accordingly.

      Example:

      Front shim thickness: -1.2 mm (-0.047 in.)

      Rear shim thickness: +1.2 mm (0.047 in.)

CAUTION: Adjust the shim thickness to 7 mm (4 -11 mm), and adjust the difference between the front and rear of the upper suspension arm shaft to within 4 mm.
NOTE: If the steering axis inclination is not as specified value after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel for distortion or looseness.
4. Torque the upper suspension arm set bolts.

   Torque: 130 Nm (1,300 kgf.cm, 94 ft.lbf) 

If the toe-in is not within the specified value, adjust the rack ends.

1. Remove the 2 clips.

3. Turn the right and left rack ends by an equal amount to adjust the toe-in.
   NOTE:

   Try to adjust the toe-in to the center of the specified value.

4. Make sure that the lengths of the right and left rack ends are the same.

   Rack end length difference: 1.5 mm (0.059 in.) or less

5. Tighten the tie rod end lock nuts.

   Torque: 54 Nm (550 kgf.cm, 40 ft.lbf) 

NOTE:

Make sure that the boots are not twisted.

6. Place the boots on the seats and install the clips.

Turn the steering wheel fully and measure the turning angle.
