DIAGNOSIS
DIAGNOSIS TABLE
Refer to SECTION 3.
BALANCING WHEELS
There are two types of wheel and tire balance: static and dynamic.
Static balance, as shown in left figure, is equal distribution of weight
around wheel. Wheels that are statically unbalanced cause bounc-
ing action called tramp. This condition will eventually cause uneven
tire wear.
Dynamic balance, as shown in left figure, is equal distribution of
weight on each side of wheel centerline so that when the tire spins
there is no tendency for the assembly to move from side to side.
Wheels that are dynamically unbalanced may cause shimmy.
GENERAL BALANCE PROCEDURE
Deposits of mud, etc. must be cleaned from inside of rim.
WARNING:
Stones should be removed from tread in order to avoid operator injury during spin balancing and to
obtain good balance.
Tire should be inspected for any damage, then balanced according to equipment manufacturer's recommendation.
OFF-VEHICLE BALANCING
Most electronic off-vehicle balancers are more accurate than on-vehicle spin balancers. They are easy to use and
give a dynamic (two plane) balance. Although they do not correct for drum or disc unbalance as does on-vehicle
spin balancing, this is overcome by their accuracy, usually to within 1 / 8 ounce.
ON-VEHICLE BALANCING
ON-vehicle balancing methods vary with equipment and tool manufacturers. Be sure to follow each manufacturer's
instructions during balancing operation.

GENERAL DESCRIPTION
The drive shaft joint is a constant velocity joint (C.V. joint) which slides in the axial direction. The joint is composed
of an outer race, cage, inner race and balls. In the turning direction, the joint rotates in the same way as a ball bear-
ing. The balls lock rotation completely and transmit drive. In addition this vehicle is also characterized by a function
that the shaft can slide through the balls in the grooves of the outer race in the extension / contraction direction of
the drive shaft.

NOTE:

All propeller shaft 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 replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly to assure proper retention of this part.

Never attempt to heat, quench or straighten any propeller shaft part. Replace it with a new part, or dam-
age to the part may result.

GENERAL DESCRIPTION
Most universal joints require no maintenance. They are lubricated for life and can not be lubricated on the vehicle.
If a universal joint becomes noisy or worn, it must be replaced.
The propeller shaft is a balanced unit. Handle it carefully so that balance can be maintained.

PROPELLER SHAFT JOINT CHECK
If universal joints are suspected of producing chattering or rattling
noise, inspect them for wear. Check to see if cross spider rattles in
yokes or if splines are worn down and replace defective propeller
shaft with new one.
Noise coming from universal joint can be easily distinguished from
other noises because rhythm of chattering or rattling is in step with
cruising speed. Noise is pronounced particularly on standing start
or in coasting condition (when braking effect of engine is showing
in the drive line).

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:

When inspecting and servicing vehicle equipped with ABS, be sure to refer to section 5E or 5E1 first.

All brake fasteners are important attaching 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 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 as-
sure proper retention of all parts. There is to be no welding as it may result in extensive damage and
weakening of the metal.

SUBSTANDARD OR
CONTAMINATED BRAKE FLUID
Improper brake fluid, mineral oil or water in the fluid
may cause the brake fluid to boil or the rubber compo-
nents in the hydraulic system to deteriorate.
If primary piston cups are swollen, then rubber parts
have deteriorated. This deterioration may also be evi-
denced by swollen wheel cylinder piston cups on the
drum brake wheels.
If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol
out of the system. Replace all rubber parts in the sys-
tem, including hoses. Also, when working on the
brake mechanisms, check for fluid on the linings. If ex-
cessive fluid is found, replace the linings.
If master cylinder piston seals are satisfactory, check
for leakage or excessive heat conditions. If condition
is not found, drain fluid, flush with brake fluid, refill and
bleed system.
The system must be flushed if there is any doubt as
to the grade of fluid in the system or if fluid has been
used which contained parts that have been subjected
to contaminated fluid.
DIAGNOSIS
ROAD TESTING BRAKES
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both
light and heavy pedal forces at various speeds to de-
termine if the vehicle stops evenly and effectively.
Also drive vehicle to see if it leads to one side or the
other without brake application. If it does, check the
tire pressure, front end alignment and front suspen-
sion attachments for looseness. See diagnosis chart
for other causes.
BRAKE FLUID LEAKS
Check the master cylinder fluid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low level indicates a leak in the
system. In such a case, check the entire brake system
for leakage. If even a slight evidence of leakage is
noted, the cause should be corrected or defective
parts should be replaced.
If fluid level is lower than the minimum level of reser-
voir, refilling is necessary. Fill reservoir with specified
brake fluid.
Brake fluid: Refer to reservoir tank cap.
CAUTION:
Since brake system of this vehicle is factory-
filled with brake fluid indicated on reservoir
tank cap, do not use or mix different type of
fluid when refilling; otherwise serious damage
will occur.
Do not use old or used brake fluid, or any fluid
from a unsealed container.
