CAUTION:

Use a ST to support steering body.

Ensure that needle bearing is free from defects. If it
is faulty, replace steering body with a new one.
NOTE:
If steering body is removed from vehicle, be sure to remove
rust and clean.

5) Apply a coat of grease to grooves in rack, sliding sur-
face of sleeve and sealing surface of piston. Install ST on
the end of steering body cylinder. Then insert rack into
steering body from cylinder side.

2. VALVE ASSEMBLY
1) Remove traces of sealer, oil, rust, etc., from mating
surfaces of valve housing and steering body.
2) Position a shim in graded portion of steering body pin-
ion housing, and apply an even coat of sealer (Fuji Bond
C: 004403004 or three bond 1105 (00440310) or equiva-
lent) to end of pinion housing.
3) Use the same number of shims as that used when
steering body was removed.
4) If steering body, valve housing or pinion and valve is
replaced with a new one, add two or three shims, install
valve on pinion housing and tighten with two bolts to 25±5
N⋅m (2.5±0.5 kg-m, 18.1±3.6 ft-lb). Then, measure clear-
ance between steering body and valve housing using a
thickness gauge. Remove shims so that the clearance is
zero.
B4M0670A
5) Extend rack“L”beyond pinion side of steering body.
L: 70.8 mm (2.787 in)
G4M0853
6) Apply grease to pinion gear teeth and ball bearing.
Insert valve into place.
7) Alternately and slowly tighten socket bolts.
NOTE:
Replace faulty parts before installing valve. Otherwise,
valve may not be installed properly.
Tightening torque:

7. Pipe Assembly (Power Steering
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.
