NOTE:
All steering system fasteners are important parts in that they 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 specified during reassembly to assure proper retention of
this part.

18-1. GENERAL DESCRIPTION
The rotary motion of the steering handwheel is carried to the steering shaft upper, steering shaft lower,
steering gear box and pitman arm. Then as the pitman arm moves, the drag rod is caused to move linearly,
actuating the tie rod to turn the wheels, right and left, through their knuckle arms. The turning force
exerted by the tie rod experiences a damping action due to the presence of the oil seal at the sphere-like
joint between the knuckle case and the inner case (integral with the dead axle sleeve). Another damping
action is available, which will be mentioned below.
The steering system formed by the components named above is designed for easy steering, high durability
and excellent steering reaction as well as reliable self-restoring action. Articulated joints in the steering
lever is equipped with a damping device for ensuring the greater steering stability.
Linkage are of wear-resistant ball-and-socket type. Pitman arm is equipped with a damping device for
ensuring the greater steering stability.

NOTE:
When removing the column assembly from the
car, special care must be taken in handling it
Use of a steering wheel puller other than the
steering wheel remover recommended in this
manual or a sharp blow on the end of the
steering shaft, leaning on the assembly, or
dropping the assembly is prohibited. Any of
such actions could shear the plastic shear pins
which maintain column length especially.
Steering Hand Wheel
1) Disconnect negative battery cable.
2) Pull horn button to remove.
Fig. 18-3
3) After loosening steering shaft nut, remove
steering wheel by using special tool.

[Adjustment of worm shaft starting torque]
The steering gear box is provided with adjust-
ing bolt @ which gives preload to sector shaft.
Fig. 18-19 (1)Adjusting bolt
Make an adjustment according to the following
procedure.
1) Check worm shaft to ensure that it is free
from thrust play.
2) Position pitman arm in parallel with worm
shaft as shown below.
(With pitman arm in this position, front
wheel is in straightforward state.)
