      8. Measure the distance between the 2 lines on the masking tape of the steering wheel.
      9. Convert the measured distance to steering angle.

      Measured distance 1 mm (0.04 in.) = Steering angle approximately 1 deg. 

      HINT:

      Make a note of the steering angle.

    2. Adjust steering angle.
      1. Draw a line on the RH and LH tie rod and on the RH and LH rack end which it can easily be seen.

        • Measure the RH side and LH side.
        • Make a note of the measured values.
      4. Remove the RH and LH boot clips from the rack boots.

      6. Loosen the RH and LH lock nuts.
      7. Turn the RH and LH rack ends by the same amount (but in different directions) according to the steering angle.

        1 turn 360 deg. of rack end (1.5 mm (0.059 in.) horizontal movement) - 12 deg. of steering angle. 

      8. Tighten the RH and LH lock nuts.

        Torque: 74 N.m (755 kgf.cm, 55 ft.lbf) 

        NOTE: Make sure that the difference in length between RH and LH tie rod ends and rack end screws are within 1.5 mm (0.059 in.).
      9. Install the RH and LH boot clips.
