System) [LHD model]
A: REMOVAL
1) Disconnect battery minus terminal.
G4M0099
2) Lift vehicle and remove jack-up plate.
3) Remove one pipe joint at the center of gearbox, and
connect vinyl hose to pipe and joint. Discharge fluid by
turning steering wheel fully clockwise and counterclock-
wise. Discharge fluid similarly from the other pipe.
CAUTION:
Improper removal and installation of parts often
causes fluid leak trouble. To prevent this, clean the
surrounding portions before disassembly and
reassembly, and pay special attention to keep dirt and
other foreign matter from mating surfaces.

5) Disconnect pipe C⋅D from pipe (on the gearbox side).
CAUTION:
When disconnecting pipe C⋅D, use two wrenches to
prevent deformities.
Be careful to keep pipe connections free from for-
eign matter.

6) Remove bolt A.
Disconnect pipe C from oil pump. Disconnect pipe D from
oil tank.
CAUTION:
Do not allow fluid from the hose end to come into
contact with pulley belt.
To prevent foreign matter from entering the hose
and pipe, cover the open ends of them with a clean
cloth.
B: CHECK
Check all disassembled parts for wear, damage or other
abnormalities. Repair or replace faulty parts as required.

11) Finally check clearance between pipes and/or hoses,
as shown above.
If clearance between cruise control pump and power steer-
ing hose is less than 10 mm (0.39 in), proceed as follows:
(1) Move clamped section
A(refer to figure above.)
down to a point where pipe is close to crossmember.
Pipe-to-crossmember clearance:
10 mm (0.39 in), min.
(2) Check that clearance between cruise control pump
and power steering hose is at least 10 mm (0.39 in). If
it is not, bend section
Bdown until a clearance of at
least 10 mm (0.39 in) is obtained.
