Steering Column Assembly Removal and
Installation

S5JB0B6206006

CAUTION

!

Once the steering column assembly is
removed from the vehicle, the column is
extremely susceptible to damage.
Dropping the column assembly on its end
could collapse the steering shaft or loosen
the plastic shear pins which maintain column
length leaning on the column assembly could
cause it to bend or deform.
Any of the above damage could impair the
column’s collapsible design.
When loosening steering column mounting
bolts and nuts, make sure that steering
column assembly and steering upper shaft
assembly have been separated. Loosening
them with steering column assembly and
steering upper shaft assembly assembled
could cause damage to upper joint and
mounting bracket in steering upper shaft
assembly.

Removal

WARNING

!

Never rest a steering column assembly on
the steering wheel with air bag (inflator)
module face down and column vertical.
Otherwise personal injury may result.

CAUTION

!

Never turn steering wheel while steering
column with steering wheel is removed.
Turning steering wheel more than about two
and a half turns will break contact coil cable
assembly.

1) Disconnect negative (–) cable at battery.
2) Disable air bag system referring to “Disabling Air

Bag System in Section 8B in related manual”.

3) Remove steering wheel and contact coil cable

assembly. Refer to “Steering Wheel Removal and
Installation in related manual” and “Contact Coil
Cable Assembly Removal and Installation”.

4) Remove instrument panel under cover (1) from

instrument panel.

5) Remove immobilizer control module (ICM) referring

to “Immobilizer Control Module (ICM) Removal and
Installation in Section 10C”.

6) Remove lighting switch referring to “Headlight Switch

(in Lighting Switch) Removal and Installation in
Section 9B in related manual”.

7) Remove washer switch referring to “Windshield

Wiper and Washer Switch Removal and Installation
in Section 9D in related manual”.

8) Disconnect connector from steering lock assembly.
9) For A/T vehicle, disconnect shift (key) interlock cable

(1) from ignition switch with ignition switch turned at
ACC position.
After disconnecting, turn ignition switch to LOCK
position.

10) Remove steering upper shaft upper joint bolt (1) and

nut (2).

6B-6 Steering Wheel and Column:

11) Remove column support bracket. (if equipped)

12) Remove steering column assembly (1) mounting

bolts (2) and nuts (3).

NOTE
Do not move tilt lever before till mounting
bolts and nuts are tightened completely.

13) Remove steering column assembly from vehicle.

Installation

CAUTION

!

After tightening steering column assembly
mounting bolts and nuts, steering shaft joint
bolts should be tightened.

1) Be sure that front wheels and steering wheel are in

straight-ahead position.

2) Align flat part “A” of steering upper shaft upper joint

(1) with bolt hole “B” of steering column assembly (2)
as shown in the figure. Then connect steering upper
shaft upper joint.

3) Install steering column assembly (1) with contacting

upper side of lower bracket slits to mounting bolts.
Tighten steering column lower mounting nuts (3) first
and then upper mounting bolts (2) to specified
torque.

Tightening torque
Steering column assembly mounting bolt and
nut (a): 25 N·m (2.5 kgf-m, 18.0 lb-ft)

4) Install column support bracket. (if equipped)
5) Install new steering upper shaft upper joint bolt (2)

and nut (1). Tighten new steering upper shaft upper
joint nut (1) to specified torque.

NOTE
Do not reuse steering upper shaft upper joint
bolt and nut.
Be sure to use new bolt and nut when
installing.

Tightening torque
Steering upper shaft assembly upper joint nut
(a): 23 N·m (2.3 kgf-m, 17.0 lb-ft)

6) For A/T vehicle, connect shift (key) interlock cable

(1) to ignition switch with ignition switch turned at
ACC position.
And then turn ignition switch LOCK position.

Power Assisted Steering System

General Description

P/S System Construction

S5JB0B6301001

The power steering (P/S) system in this vehicle reduces the driver’s effort needed in turning the steering wheel by
utilizing the hydraulic pressure generated by the power steering (P/S) pump (2) which is driven by the engine.
It is an integral type with the rack and pinion gears and the control valve unit, hydraulic pressure cylinder unit all built in
the steering gear case (1).

Steering Gear Case Construction

S5JB0B6301002

The steering gear case consists of two sections: one
including a cylinder and the other a valve. Main
components of the cylinder section are a gear case (7), a
rack (8) and a tube and those of the valve section are a
valve case (10), a sleeve (4) and a stub shaft (2). The
sleeve is linked with the pinion (6) through a pin (1) and
the valve and stub shaft are integrated into one unit.
Then the pinion and the stub shaft are linked to each
other by means of the torsion bar (3).
Thus, when the stub shaft moves, the valve changes its
position, thereby switching the hydraulic passage from
the pump to the cylinder to help steering operation.
When turning the steering wheel feels heavy due to P/S
fluid leakage or for some other reason (i.e., when in the
manual steering mode), the stub shaft and pinion are in
direct linkage and the force is output directly through the
pinion and rack.
