8. Remove steering hydraulic piping bracket from front suspension member. Refer to PS-38, "HYDRAULIC
LINE" .
9. Remove EPS solenoid valve harness connector. Refer to PS-20, "
COMPONENTS" .
10. Remove rack stay (2WD) or front cross bar (AWD). Refer to FSU-8, "
Components" , FSU-25, "Compo-
nents" .
11. Remove mounting bolts and nuts of steering gear assembly, and then remove steering gear assembly
from vehicle.
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-18, "COMPONENTS" .
When installing lower joint to steering gear assembly, follow the procedure listed below.
–Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn gear-sub assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower joint (C) aligning with the projection (A) of
rear cover cap (1). Make sure that the slit part of lower joint (C)
is aligned with both the projection (A) of rear cover cap (1) and
the marking position (B) of gear housing assembly.
After installation, bleed air from the steering hydraulic system.
Refer to PS-8, "
Air Bleeding Hydraulic System" .
Perform final tightening of nuts and bolts on each part under
unladen conditions with tires on level ground when removing
steering gear assembly. Check wheel alignment. Refer to FSU-
6, "Wheel Alignment Inspection" , FSU-23, "Wheel Alignment
Inspection" .
Adjust neutral position of steering angle sensor after checking wheel alignment. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .
INSPECTION AFTER INSTALLATION
Make sure that steering wheel operates smoothly by turning several times from full left stop to full right stop.
