Caster (Air suspension models) 

Steering axis inclination 

If the steering axis inclination is not within the specified values, after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel bearing for looseness.

1. Loosen the front and/or rear adjusting cam set bolts.
2. Adjust the camber and caster by turning the front and/or rear adjusting cams (See Fig 4 ).

   HINT:

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

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

      Example: 

      • Camber: 0°08' (0.13°) 
      • Caster: 2°59' (2.98°)

   3. Measure the present wheel alignment value with the vehicle unloaded.
   4. Mark the measured present value on the adjustment chart.

      Example: 

      • Camber: 0°20' (0.33°) 
      • Caster: 2°59' (2.98°) 
   5. As shown in Fig 5 and Fig 6 , read the distance from the measured value to the standard value, and adjust the front and/or rear adjusting cams accordingly.

      Amount to turn the adjusting cams (by graduation): 

      Example 

      • Front cam: 1.4 (+ direction) 
      • Rear cam: 1.3 (+ direction)

2. Loosen the tie rod end lock nuts.
3. Turn the right and left rack ends by an equal amount to adjust the toe-in.

   HINT:

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

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: 55 N*m (560 kgf*cm, 41 ft.*lbf) 

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

   HINT:

   Make sure that the boots are not twisted.

7. Inspect the wheel angle.
   1. Turn the steering wheel fully and measure the turning angle.
