7) Measure preload of pinion bearing with spring balance (1) or
torque wrench (2) and check composite preload of pinion
bearing and side bearing.
Composite preload of pinion bearing and side bearing
: 1.1 – 2.0 N·m (11.0 – 20.0 kg-cm, 9.5 – 17.4 lb-in.)
Spring measure reading with special tool
: 19.5 – 35.5 N (1.95 – 3.55 kg, 4.30 – 7.83 lb)
Special tool
(D) : 09922-76560
8) Torque bearing cap bolts (2) to specification and install bear-
ing lock plates.
Tightening torque
Lock plate bolt (b) : 12 N·m (1.2 kg-m, 9.0 lb-ft)
Bearing cap bolt (c) : 85 N·m (8.5 kg-m, 61.5 lb-ft)
9) As final step, check gear tooth contact as follows.
a) After cleaning 10 drive bevel gear teeth, paint them with
gear marking compound evenly by using brush or sponge
etc.
b) Turn gear to bring its painted part in mesh with drive bevel
pinion and turn it back and forth by hand to repeat their con-
tact.
c) Bring painted part up and check contact pattern, referring
to following chart. If contact pattern is not normal, readjust
or replace as necessary according to instruction in chart. NOTE:
Before taking measurement with spring balance (1) or
torque wrench (2), check for smooth rotation by hand.
On measuring preload, rotate the drive bevel pinion
about 1 rotation per 2 seconds.
3. Universal joint flange
4. Socket with adapter
1. Lock plate bolt
NOTE:
Be careful not to turn drive bevel gear more than one full
revolution, for it will hinder accurate check.
1. Brush
“A”: Paint gear marking compound evenly

10) Upon completion of gear tooth contact check in Step 9),
caulk flange nut (2) with caulking tool (1) and hammer.

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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual

•As shown in the figure, use a 12 V battery to connect its (+)
terminal to terminal “A”, and its (–) terminal to “Black” lead
wire (2).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm,
it is proper. For high speed check, connect battery (+) termi-
nal to terminal “B”, and its (–) terminal to “Black” lead wire
(2). If motor rotates at a high revolution speed of 67 to 83
rpm, it is proper.
•Testing automatic stop action.
a) Connect 12 V battery (+) terminal to terminal “A” of wiper
motor and (–) terminal to Black lead wire (2) and let the
motor turn.
b) Disconnect terminal “A” from battery, and let the motor
stop.
c) Connect terminal “A” and “D” with a jumper wire (3), and
connect terminal “C” to battery (+) terminal. Observe the
motor turns once again then stops at a given position.
d) Repeat a) through c) several times and inspect if the motor
stops at the given position every time.
