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

        Measured distance One mm (0.04 in.) = Steering angle approximately One degree. 

      NOTE: Make a note of the steering angle.
    2. Adjust steering angle.
      1. Draw a line on the RH and LH tie rod and rack ends where it can easily be seen.
