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

(7) Convert the measured distance to steering angle.

Standard:

Measured distance 1 mm (0.0397 in.) = Steering angle approximately 1 deg.

HINT:

Make a note of the steering angle.

(b) Adjust the steering angle.

(1) Lift up the vehicle.

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

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

HINT:

Make a note of the measured values.

(4) Remove the boot clip RH and LH from the rack boots.

(5) Loosen the lock nut RH and LH.

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

Standard:

1 turn 360 deg. of rack end (1.5 mm (0.0596 in.) horizontal movement) = 12 deg. of steering angle

(7) Tighten the lock nut RH and LH to the specified torque.

Torque:

82 N·m {836 kgf·cm, 60 ft·lbf}
