INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-17, "COMPONENTS" .
When installing lower shaft 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 pinion 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 shaft (C) aligning with the projection (A)
of rear cover cap (1). Make sure that the slit part of lower shaft
(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-39, "
HYDRAULIC LINE" .
–Perform final tightening of nuts and bolts on each part under
unladen conditions with tyres on level ground when removing
steering gear assembly. Check wheel alignment. Refer to FSU-
5, "Wheel Alignment Inspection" .
–Adjust neutral position of steering angle sensor after checking the wheel alignment for the models with
VDC. Refer to BRC-40, "
Adjustment 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.
