General Description
This section describes operation, installation and maintenance of free wheeling hub. Be sure to refer to
this section carefully for proper service.
Operation
A free wheeling hub should be fitted onto each of the right and left front wheel hubs. The free wheeling
hub has a knob and two embossed marks,“FREE” and “LOCK”. When the knob is set to the “FREE”
position, the axle shaft and wheel are disconnected and the revolution of the front wheels becomes free.
When it is set to the “LOCK” position, the axle shaft and wheel are connected.

7) To check free wheeling hub operation, jack
up the front end, move the knob of free
wheeling hub between “FREE” and “LOCK”
positions and check for smoothness. Also
check if wheel operates correctly with the
knob at “FREE” and “LOCK” positions
and by rotating wheel by hand.
Maintenance Service
The car equipped with free wheeling hubs are
subject to the following periodical checks.
To check free wheeling hubs operation, jack up
the front end, move the knob of free wheeling
hub between “FREE” and “LOCK” positions
and check for smoothness. Also check if wheel
operates correctly with the knob at “FREE”
and “LOCK” positions and by rotating wheel by
hand.
Should the check result be unsatisfactory,
remove free wheeling hub cover and grease each
sliding surface with SUZUKI SUPER GREASE
A (99000-25010) or multipurpose grease after
cleaning each sliding part.
If faulty operation is still noted even after
greasing, correct defective part or replace it
with a new one.
CAUTION:
Hubs should not be packed with grease.
For installation, refer to “Installation Instruc-
tion” in this section.

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.
