Steering System
INSPECTION
1) Check steering wheel for play and rattle, holding vehicle in
straight forward condition on the ground.
Steering wheel play
“a”: 0 – 30 mm (0 – 1.2 in.)
2) Check universal joints of steering lower shaft (1) for rattle
and damage. If rattle or damage is found, replace defective
part with a new one.
3) Check steering linkage (including kingpin) for looseness and
damage. Repair or replace defective part, if any.
4) Check bolts and nuts for tightness and retighten them as
necessary. Repair or replace defective parts, if any.
Refer to table of “Tightening Torque Specifications” in Sec-
tion 3B (or 3B1) and 3C for particular check points.
5) Inspect steering gear box (2) for evidence of oil leakage. If
leakage is found, check oil level in gear box.
6) Check boots of steering linkage for damage (leaks, detach-
ment, tear, dent, etc.). If damage is found, replace defective
boot with new one.
7) Check wheel alignment. Refer to “Preliminary Checks Prior
to Adjusting Front Alignment” in Section 3A.
Steering Knuckle Seal
INSPECTION
1) Remove knuckle seal cover (1).
2) Check knuckle seal (2) for wear, damage and deterioration.
If defective, replace.
3) Apply grease to seal lip and install seal and seal cover.

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.

Leading Arm Bushing / Lateral Rod Bushing
Check
Inspect for damage, wear or deterioration.
If defective, replace.
Kingpin / Kingpin Bearing Check
1) Inspect for wear or deterioration.
2) Inspect for crack, damage or deformation of kingpin.
If defective, replace.
Barfield Joint Check
To be checked on this joint is its axial play, which shows up when
a push-and-pull motion is given to live axle shaft and wheel spin-
dle held in both hands, as shown in figure. There should be no
play at all but a play of up to 1.5 mm (0.06 in.) is permissible. If
play exceeds service limit, replace it.
Axial play in barfield joint
Steering Knuckle Seal Check
The knuckle seal used at the spherical sliding joint between the
knuckle and the inner case accomplishes the additional purposes
of keeping out road dust and of acting as the damper for the
steering handwheel. As the wear of this seal advances, its damp-
ing effect decreases and thus make the front wheel develop a ten-
dency to “shimmy” not only that road dust begins to creep into the
sliding clearance to promote the wear of the spherical sliding sur-
faces.
Check the knuckle seal for wear or damage. If defective, replace
with new one.
Standard Service Limit
0 mm (no play) 1.5 mm (0.06 in.)

the air locking hub cannot be locked or unlocked.
Therefore, be careful not to apply too much grease to
avoid clogging the vacuum passage.
