(7) Measure the distance between the 2 lines on the masking tape on the steering wheel assembly.

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

HINT:

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

(b) Adjust the steering angle.

(1) Put matchmarks on the tie rod assemblies LH and RH and steering rack end sub-assembly respectively.

(2) Using a paper gauge, measure the thread length of the steering rack end sub-assemblies.

HINT:

• Measure both RH and LH sides.
• Make a note of the measured values.

(3) Remove the steering rack boot clips from the RH and LH steering rack boots.

(4) Loosen the RH and LH lock nuts.

(5) Turn the RH and LH steering rack end sub-assemblies by the same amount (but in different directions) according to the measured steering angle.

HINT:

One 360 degree turn of a steering rack end sub-assembly (1.5 mm (0.0591 in.) horizontal movement) equals 9.2 degrees of 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 thread length between the RH and LH steering rack end sub-assemblies is within 1.5 mm (0.0591 in.).

(7) Install the RH and LH steering rack boot clips.

HINT:

Make sure that the tabs of the RH and LH steering rack boot clips are positioned within the area shown in the illustration.
