    5. Turn the steering wheel to the center position.

      HINT:
      Look at the upper surface of the steering wheel, steering spoke, and SRS airbag line to find the center position.

    8. Measure the distance between the 2 lines on the masking tape on the steering wheel.

    9. Convert the measured distance to steering angle.

      Standard:
      Measured distance 1 mm (0.0397 in.) = Steering angle approximately 1 deg.
      HINT:
      Make a note of the steering angle.


  1. Adjust steering angle.

    3. Using a paper gauge, measure the distance from the RH and LH tie rod ends to the rack end screws.

      HINT:
      1. Measure both the RH and LH sides.
      2. Make a note of the measured values.
    4. Remove the RH and LH boot clips from the rack boots.

    5. Loosen the RH and LH lock nuts.

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

      Standard:
      Tire Size
      Steering Angle
      P195/50R16
      1 turn (360 deg.) of rack end (1.5 mm (0.0591 in.) horizontal movement) = 9.6 deg. of steering angle
      except P195/50R16
      1 turn (360 deg.) of rack end (1.5 mm (0.0591 in.) horizontal movement) = 10.8 deg. of steering angle
    7. Tighten the RH and LH lock nuts to the specified torque.

      Torque:
      75 N*m{765 kgf*cm, 55 ft.*lbf}
      NOTICE:
      Make sure that the difference in length between the RH and LH tie rod ends and rack end screws is within 1.5 mm (0.0591 in.).

      NOTICE:
      1. Install the clip so that its claws are within the clip installation range.
      2. Make sure that the rack boots are not twisted.
