Adjustment [04/2013 - 10/2016]: Procedure

  1. STEERING WHEEL OFF CENTER ADJUSTMENT PROCEDURE 
    1. Inspect steering wheel off center.
      1. Turn the steering wheel assembly to the center position.
      2. Apply masking tape to the top center of the steering wheel assembly and steering column cover (upper).

        *a Masking Tape
      3. Drive the vehicle in a straight line for 100 m (328 ft.) at a constant speed of 56 km/h (35 mph), while holding the steering wheel assembly to maintain the course.
      4. Draw a line on the masking tape as shown in the illustration.

      5. Turn the steering wheel assembly to the center position.

        HINT: 

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

      6. Draw a new line on the masking tape on the steering wheel assembly as shown in the illustration.

        *2 Steering Wheel Assembly
        *a Marked Line
      7. Measure the distance between the 2 lines on the masking tape on the steering wheel assembly.
      8. Convert the measured distance to steering angle.

        HINT: 

        • Measured distance 1 mm (0.0394 in.) = Steering angle of approximately 1 degree
        • Make a note of the steering angle.
    2. Adjust the steering angle.
      1. Put matchmarks on the tie rod assemblies LH and RH and steering rack end sub-assembly respectively.

      2. Using a paper gauge, measure the thread length of the steering rack end sub-assemblies.

        HINT: 

        • Measure both RH and LH sides.
        • Make a note of the measured values.
      3. Remove the steering rack boot clips from the RH and LH No. 1 steering rack boots.

      4. Loosen the RH and LH lock nuts.
      5. Turn the RH and LH steering rack end sub-assemblies by the same amount (but in different directions) according to the measured steering angle.

        HINT: 

        One 360 degree turn of a rack end (1.5 mm (0.0591 in.) horizontal movement) equals 12 degrees of steering angle.

      6. Tighten the RH and LH lock nuts to the specified torque.

        Torque: 55.9 N*m (570 kgf*cm, 41 ft.*lbf) 

        NOTE:

        Make sure that the difference in thread length between the RH and LH steering rack end sub-assemblies is within 1.5 mm (0.0591 in.).

      7. Install the RH and LH steering rack boot clips.

        HINT: 

        Make sure that the claws of the clip are facing in the direction that the vehicle travels.

      8. Perform variable gear ratio steering zero point calibration (w/ VGRS).

        Refer to CALIBRATION [04/2013 - 10/2016]
