                                                | *a | Marked Line |  |  |  (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 (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:  74 N·m {755 kgf·cm, 55 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. |
