Checking Steering Column for Accident Damage
CHECKING PROCEDURE
1) Check that two capsules (1) are attached to steering column
bracket (2) securely. Check clearance between capsules (1)
and steering column bracket (2). Clearance should be 0.0
mm (0.0 in.) on both sides.
If found loose or clearance, replace steering column assem-
bly.
2) Check two plates (3) for any damages such as crack or
breakage.
If anything is found faulty, replace as steering column assem-
bly.
3) Take measurement “a” as shown.
If it is shorter than specified length, replace column assem-
bly (1) with new one.
Steering column assembly length
“a” : 733.2 – 734.8 mm (28.87 – 28.93 in.)
4) Check if steering lower shaft (1) is with in specified length.
If it is out of specified length, replace it with new one.
Steering lower shaft length
“b” : 478.3 – 480.3 mm (18.83 – 18.91 in.)
(For LH steering vehicle without P/S system)
438.3 – 440.3 mm (17.26 – 17.33 in.)
(For RH steering vehicle without P/S system)
393.6 – 395.6 mm (15.50 – 15.57 in.)
(For LH steering vehicle with P/S system)
434.2 – 436.2 mm (17.09 – 17.17 in.)
(For RH steering vehicle with P/S system)
5) Check steering column lower seal (1) for breakage or defor-
mation.
If found defective, replace. NOTE:
Vehicles involved in accidents resulting in body damage, where steering column has been impacted
(or air bag deployed) may have a damaged or misaligned steering column.

6) Check steering shaft joints and shaft for any damages such
as crack, breakage, malfunction or excessive play.
If anything is found faulty, replace as lower joint assembly or
column assembly.
7) Check steering shaft for smooth rotation.
If found defective, replace as column assembly.
8) Check steering shaft and column for bend, cracks or defor-
mation.
If found defective, replace.

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.

Components and Functions
Component Function
4WD switch When the transfer shift lever is shifted to 4L or 4H position from 2H, this switch
turns ON and cause the 4WD control system to turn ON.
4WD controller When the 4WD switch turns on, the 4WD controller activates VSV2 to lock the
air locking hubs and when it receives an “ON” signal from the vacuum switch, it
makes VSV2 to complete operation within 5 seconds and causes the 4WD indi-
cator light to light up.
If vacuum in the vacuum circuit fails to reach the specified level due to a leakage
in the vacuum circuit (when no “ON” signal is inputted from the vacuum switch),
the 4WD controller stops operation of VSV2 in 15 seconds and makes the 4WD
indicator light to flash to warn occurrence of a trouble.
When the 4WD switch turns off, the 4WD controller activates VSV1 for 10 sec-
onds to unlock the hubs and at the same time makes the 4WD indicator light
turn off.
VSV1 VSV1 operates according to the signal from the 4WD controller. When it is acti-
vated, the port opens and vacuum in the intake manifold is applied through the
vacuum circuit to unlock to the slide gear in the air locking hub. As a result, the
air locking hubs are unlocked.
VSV2 VSV2 operates according to the signal from the 4WD controller. When it is acti-
vated, the port opens and vacuum in the intake manifold is applied through the
vacuum circuit to lock to the slide gear in the air locking hub. As a result, the air
locking hubs are locked.
Vacuum switch When VSV2 receives the “ON” signal from 4WD switch, vacuum is applied
through its circuit to the vacuum switch. The vacuum switch turns on when it
detects vacuum exceeding 260 mmHg.
“4WD” indicator lamp It lights up when 4WD control system is in the 4WD mode.
It flashes to warn that locking hub operation has not completed (4WD control
system fails to shift 4WD).

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.
