2) Loosen and remove steering lock mounting bolts (2) using
center punch (1) as shown.
3) Turn ignition key to “ACC” or “ON” position and remove
steering lock assembly from steering column.
INSTALLATION
1) Position oblong hole (1) of steering shaft in the center of hole
(3) in column (4).
2) Turn ignition key to “ACC” or “ON” position and install steer-
ing lock assembly (5) onto column (4).
3) Now turn ignition key to “LOCK” position and pull it out.
4) Align hub on lock with oblong hole (1) of steering shaft and
rotate shaft to assure that steering shaft (2) is locked.
5) Tighten new bolts until head of each bolt is broken off.
6) Turn ignition key to “ACC” or “ON” position and check to be
sure that steering shaft rotates smoothly. Also check for lock
operation.
7) Install steering column referring to “Steering Column” in this
section.
Steering Lower Shaft
REMOVAL
1) Turn steering wheel so that vehicle’s front tires are at
straight-ahead position.
2) Turn ignition switch to “LOCK” position and remove key. NOTE:
Use care not to damage aluminum part of steering lock
body with center punch.
CAUTION:
For vehicle with air bag system
Never turn steering wheel while steering shaft lower joint
is removed.
Should it have been turned and contact coil (on combina-
tion switch) have got out of its centered position, it needs
to be centered again. Also, turning steering wheel more
than about two and a half turns will break contact coil.

WARNING:
When hoisting vehicle, be sure to select the lifting point suitable for the service work referring to Sec-
tion 0A.
NOTE:
All front suspension fasteners are an important attaching part in that it could affect the performance
of vital parts and systems, and/or could result in major repair expense. They must be replaced with
one of the same part number or with an equivalent part if replacement becomes necessary. Do not
use a replacement part of lesser quality or substitute design. Torque values must be used as speci-
fied during reassembly to assure proper retention of this part.
Never attempt to heat, quench or straighten any front suspension part. Replace it with a new part or
damage to the part may result.

General Description
4WD Control System
The 4WD control system consists of a 4WD switch, a vacuum switch, a vacuum tank, two vacuum switching
valves (VSV1 and VSV2) and air locking hub assemblies.
The 4WD controller controls locking or unlocking of the air locking hub according to operation of the transfer shift
control lever.
Vacuum generated in the intake manifold passes through the check valve and stored in the vacuum tank.
According to signals from the 4WD switch, the 4WD controller activates VSV1 (for unlocking) or VSV2 (for lock-
ing) to apply vacuum from the vacuum tank so that the front axle and the wheel hub are disengaged or engaged.

OPERATION
2WD
→ 4WD
When the transfer shift control lever is shifted from the 2WD (2H) position to the 4WD (4H or 4L) position, a 4WD
“ON” signal is transmitted to the 4WD controller which then activates VSV2 to apply vacuum in the intake mani-
fold to the chamber “B” in the hub housing.
When vacuum is applied, the slide gear is separated from the magnet, moves toward the center of the vehicle
body and gets engaged with the outer gear. In this way, the front axle shaft and the front wheel hub rotate as one
unit.
If vacuum in the circuit fails to reach 260 mmHg within 15 seconds after operation of VSV2 due to such trouble
as a hole in the vacuum pipe, the slide gear does not operate and the 4WD indicator light flashes to warn that
the hub is unlocked.

4WD
→ 2WD
When the transfer shift control lever is shifted from the 4WD (4H or 4L) to the 2WD (2H) position, the 4WD con-
troller activates VSV1 and the intake manifold vacuum is applied to the chamber “A” in the hub housing. As the
slide gear is shifted to the wheel side by the vacuum force and disengaged from the outer gear, rotation of the
front wheel hub is not transmitted to the front axle shaft.

Wheel Disc, Nut and Bearing Check
1) Inspect each wheel disc for dents, distortion and cracks.
Disc in badly damaged condition must be replaced.
2) Check wheel nuts for tightness and as necessary, retighten
them to specification.
Tightening torque
Wheel nuts
(a) : 95 N·m (9.5 kg-m, 69.0 lb-ft)
3) Check wheel bearing for wear. After retightening lock nut to
specified torque, apply dial gauge to wheel hub center and
measure thrust play.
Wheel bearing thrust play limit
: 0.05 mm (0.002 in)
When measurement exceeds limit, replace bearing.
4) By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If defective, replace bearing.
