STEERING SYSTEM ADJUSTMENT

PROCEDURE


  1. ADJUST STEERING CENTER

    Tech Tips

    This is the adjustment procedure for when the steering is off center.


    1. Check if the steering wheel is off center.

        *a Masking Tape

        Apply masking tape to the top center of the steering wheel and steering column upper cover.

      2. Drive the vehicle in a straight line for 100 m (328 ft.) at a constant speed of 56 km/h (35 mph), and hold the steering wheel to maintain the course.

        *a Marked Line

        Draw a line on the masking tape as shown in the illustration.

      4. Turn the steering wheel to the center position.

        Tech Tips

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

        *a Marked Line

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

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

      7. Convert the measured distance to steering angle.

        Tech Tips


        • Measured distance of 1 mm (0.0394 in.) = Steering angle of approximately 1 degree.

        • Make a note of the steering angle.

    2. Adjust the steering angle.


      1. A01W9IEC01
        *1 Rack End
        *a Matchmark

        Draw a line on the RH and LH tie rod ends and rack ends where it can be easily seen.

      2. Measure the distance from the RH and LH tie rod ends to the ends of the rack end screws.

        Tech Tips


        • Measure both the RH and LH sides.

        • Make a note of the measured values.

      3. Loosen the RH and LH lock nuts.

      4. B0068JFN01

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

        Note

        Make sure that the thread length (A) is equal to the standard value to securely connect the tie rod end and rack end.

        Thread length (A)
        for 2WD
        20 mm (0.7874 in.) or less
        for 4WD and Pre-Runner
        17 mm (0.6693 in.) or less

        Tech Tips

        One 360 degree turn of the rack ends (1.0 mm (0.0394 in.)) horizontal movement equals 12 degrees of steering angle.

      5. A01W8GLC01
        *a Torque Wrench Fulcrum Length

        Using SST, tighten the RH and LH lock nuts to the specified torque.

        SST
        09922-10010
        Torque:
        Specified tightening torque
        60.6 N*m  { 618 kgf*cm, 45 ft.*lbf }

        Note

        Make sure that the boots are not twisted.

        Tech Tips


        • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
