6. Measure the distance between the 2 lines on the masking tape on the steering wheel.
7. Calculate the measured distance in terms of steering angle.
  Reference:
  
  1 mm (0.04 in.) = 1°
  
  HINT:
  
  Make a note of the steering angle.
ADJUST STEERING ANGLE
1. Draw a line on the RH and LH tie rod ends and rack ends respectively where it can be easily seen.

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

  - Make a note of the measured values.
3. Remove the RH and LH boot clips from the rack boots.

4. Loosen the RH and LH lock nuts.
5. Turn the RH and LH rack ends by the same amount but in different directions according to the steering angle.
  Reference:
  
  One 360° turn of rack end (1.5 mm (0.059 in.) horizontal movement) is equal to 13° of steering angle.
6. Tighten the RH and LH lock nuts.
  Torque: 56 N.m (570 kgf.cm, 41 ft.lbf)
  
  NOTE: Make sure that the difference in length between the RH and LH tie rod ends and rack end screws are within 1.5 mm (0.059 in.).
7. Install the RH and LH boot clips.
