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

(7) Convert the measured distance to the steering angle.

HINT:

  • Measured distance 1 mm (0.0394 in.) = Steering angle of approximately 1°.
  • Make a note of the steering angle.

(b) Adjust the steering angle.

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

HINT:

  • Measure both the RH and LH sides.
  • 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.

HINT:

One 360° turn of a rack end (1.5 mm (0.0591 in.) horizontal movement) is equal to a 12° change in steering angle.

(6) Tighten the RH and LH lock nuts.

Torque:

56 N·m {566 kgf·cm, 41 ft·lbf}

NOTICE:

Make sure that the difference in length between the RH and LH tie rod ends and rack end screws is less than 1.5 mm (0.059 in.).
