(2) Using a paper gauge, measure the distance from the 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 value.

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 to the specified torque.

Torque:

88 N·m {897 kgf·cm, 65 ft·lbf}

NOTICE:

Make sure that the difference in length between the RH and LH tie rod ends and rack end screws is within 1.5 mm (0.0591 in.).
