Removal

CAUTION:
Be sure to set front wheels (tires) in straight direction and remove ignition key from key cylinder before the following steps, otherwise contact coil of air bag system may get damaged.

1) Take out fluid in P/S fluid reservoir with syringe or such.
2) Remove steering joint cover.
3) Make alignment marks (1) on pinion shaft (2) and joint of steering lower shaft (3) for a guide during reinstallation.
4) Loosen joint bolt (steering column side) (4) and remove joint bolt (pinion shaft side) (5), and then disconnect steering lower shaft (3) from pinion shaft (2).





5) Disconnect high pressure pipe (1) and low pressure return hose (2).





6) Remove front suspension frame with steering gear case from vehicle.
7) Remove cylinder pipes (3) and (4) from steering gear case, using flare nut wrench.

NOTE:
As fluid flows out of disconnected joints, put a receptacle under joints or a plug to pipe.

8) Disconnect high pressure pipe (1) and low pressure return hose (2) from steering gear case, using flare nut wrench.

NOTE:
As fluid flows out of disconnected joints, have a container under joints or a plug to pipe.





Installation
1) Install cylinder pipes (4) and (5) to steering gear case using flare nut wrench.

Tightening torque
Cylinder pipe A (a): 13 Nm (1.3 kg-m, 9.5 lbf-ft)
Cylinder pipe B (a): 13 Nm (1.3 kg-m, 9.5 lbf-ft)

2) Install high pressure pipe (1) and low pressure return pipe (2) to steering gear case and then connect low pressure return hose (3) to low pressure return pipe (2).

Tightening torque
High pressure pipe (b): 35 Nm (3.5 kg-m, 25.5 lbf-ft)
Low pressure return pipe (b): 35 Nm (3.5 kg-m, 25.5 lbf-ft)





3) Install grommet (1) as shown in figure.








4) Install steering gear case to suspension frame (3) as follows.
a) Set member bracket (2) to steering gear case (1).
b) Install all steering gear case mounting bolts by hand.
c) Tighten steering mounting bolts in numerical order and specified torque.

Tightening torque

5) Install front suspension frame with steering gear case to vehicle referring to Steps 4) - 22) of Front Suspension Frame, Stabilizer Bar and/or Bush Removal and Installation (2WD Model) or Front Suspension Frame, Stabilizer Bar and/or Bush Removal and Installation (4WD Model).
6) Connect high pressure pipe (1) and low pressure return hose (2) to specified torque.

Tightening torque
P/S pump high pressure pipe union bolt (a): 65 Nm (6.6 kg-m, 48.0 lbf-ft)





7) Be sure that steering wheel and brake discs (right and left) are all straight-ahead position and then insert steering lower shaft (1) into steering pinion shaft (2) with matching marks (3).
8) Tighten steering shaft joint lower bolt (4) and upper bolt (5) to specified torque (tighten lower side first and then tighten upper side).

Tightening torque
Steering lower shaft assembly lower joint bolt (a): 25 Nm (2.5 kg-m, 18.5 lbf-ft)
Steering lower shaft assembly upper joint bolt (b): 25 Nm (2.5 kg-m, 18.5 lbf-ft)





9) Install steering joint cover.
10) After installation, be sure to fill specified power steering fluid and bleed air.
11) Check toe setting. Adjust as required.
