Power Assisted Steering System: 6C-6

Repair Instructions

P/S Fluid Level Check

S5JB0B6306002

With engine stopped, check fluid level indicated on P/S
fluid reservoir, which should be between “UPPER” and
“LOWER” marks. If it is lower than “LOWER” mark, fill
fluid up to “UPPER” mark.

NOTE

• Be sure to use an specified power steering

fluid.

• Fluid level should be checked when fluid is

cool.

P/S Fluid Leakage Check

S5JB0B6306003

Start engine and turn steering wheel fully to the right and
left so that maximum hydraulic pressure is provided.
Then visually check P/S gear case assembly (1), P/S
pump (2) and P/S fluid reservoir (3) themselves and
each joint of their connecting pipes for leakage.

CAUTION

!

Never keep steering wheel turned fully for
longer than 10 seconds.

Installation

S5JB0B6306014

CAUTION

!

Never disassemble P/S gear case assembly.
Disassembling will adversely affect original
performance of P/S gear case assembly.

Removal

1) Disconnect negative (–) cable at battery.
2) Take out P/S fluid in reservoir with syringe or such.
3) Hoist vehicle and remove both right and left wheels.
4) Disconnect both right and left tie-rod ends from

knuckle referring to Step 2) to 3) of “Removal” in
“Tie-Rod End Removal and Installation in related
manual”.

5) Remove generator referring to “Generator

Dismounting and Remounting in Section 1J”.

6) Remove P/S pump referring to “P/S Pump Removal

and Installation”.

7) Remove P/S pump bracket (1).

8) Disconnect steering lower shaft assembly (1) from

pinion shaft of P/S gear case assembly (2) referring
to Step 5) of “Removal” in “Steering Lower Shaft
Assembly Removal and Installation in Section 6B in
related manual”.

9) Disconnect high pressure pipe (3) from P/S gear

case assembly.

10) Disconnect low pressure pipe (4) from P/S gear case

assembly.

11) Remove P/S gear case cylinder pipes (5) from P/S

gear case assembly.

14) Remove bolts (1) and then take off P/S gear case

assembly from left side of vehicle.

NOTE
P/S gear case assembly cannot be removed
from the right side of vehicle.

Installation
Reverse removal procedure for installation of P/S gear
case, noting the following points.
• After confirming that front tire is in straight position,

install P/S gear case to body temporarily. Next, with
tie-rod end installed to knuckle, set rack in position
close to neutral. Then obtain the neutral state by
aligning match marks (1) on pinion shaft and steering
gear case (2) and insert steering lower joint into pinion
shaft.
Refer to Step 3) of “Installation” in “Steering Lower
Shaft Assembly Removal and Installation in Section
6B in related manual”.

CAUTION

!

Be sure to confirm that steering wheel and
front tires (wheels) are in straight position
when inserting steering lower joint into
steering pinion shaft.

• If a plug was put to disconnected pipe when removing

steering gear case, remove that plug before
reconnecting pipe.

• Use specified torque as given below.

Tightening torque
Steering lower shaft bolt: 25 N·m (2.5 kgf-m, 18.5
lb-ft)
Gear case high pressure pipe union bolt: 35 N·m
(3.5 kgf-m, 25.5 lb-ft)
Gear case cylinder pipe flare nut: 25 N·m (2.5 kgf-
m, 18.0 lb-ft)
Gear case mounting bolt: 105 N·m (10.5 kgf-m,
76.0 lb-ft)
Gear case low pressure pipe flare nut: 35 N·m (
3.5 kgf-m, 25.5 lb-ft)
P/S pump bracket bolt: 55 N·m (5.5 kgf-m, 40.0 lb-
ft)
Stabilizer bar mount bracket mount bolt (a): 60
N·m (6.0 kgf-m, 43.0 lb-ft)

• After installation, be sure to fill specified P/S fluid and

bleed air. Refer to “P/S System Air Bleeding
Procedure in related manual”.

• Check toe setting. Adjust as required. Refer to “Front

Wheel Alignment Inspection and Adjustment in
Section 2B in related manual”.
