FLUID COOLER HOSE CHANGE
Replace inlet and outlet hoses of cooler hose and their clamps.
For replacement procedure, refer to “Oil Cooler Hoses” in Section
7B.
Transfer and Differential Oil
INSPECTION
1) Check transfer case and differential for evidence of oil leak-
age.
Repair leaky point if any.
2) Make sure that vehicle is placed level for oil level check.
3) Remove level plug of transfer and differentials (front and
rear) and check oil level.
Oil level can be checked roughly by means of level plug hole.
That is, if oil flows out of level plug hole or if oil level is found
up to hole when level plug is removed, oil is properly filled.
If oil is found insufficient, pour specified amount of specified
oil.
4) Tighten level plug to specified torque.
Refer to “Oil Change” in Section 7D, 7E or 7F for tightening
torque.
CHANGE
Change transfer oil and differentials oil with new specified oil
referring to “Oil Change” in Section 7D, 7E or 7F.
[A] : Transfer
[B] : Front differential
[C] : Rear differential
1. Oil filler/level plug (Apply sealant for transfer)
2. Drain plug (Apply sealant)
CAUTION:
Hypoid gear oil must be used for differential.

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.
“a”: Grease 99000-25010

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).
CAUTION:
The air conditioning system of this vehicle uses refrigerant HFC-134a (R-134a).
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using refrigerant HFC-134a (R-134a) and the other using refrigerant CFC-12 (R-12).
Be sure to check which refrigerant is used before any service work including inspection and mainte-
nance. For identification between these two types, refer to “Refrigerant Type” in this section.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.
NOTE:
For basic servicing method of the air conditioning system that is not described in this section, refer to
AIR CONDITIONING BASIC MANUAL (Part number: 99520-02130).

Refrigerant Recovery, Evacuating and Charging
Operation Procedure for Refrigerant Charging
WARNING:
 Your eyes should not be exposed to refrigerant (liquid).
Any liquid HFC-134a (R-134a) escaping by accident shows a temperature as low as approximately
–6 °C (21 °F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause
a serious injury. To protect your eyes against such accident, it is necessary to always wear gog-
gles. Should it occur that HFC-134a (R-134a) strikes your eyes(s), consult a doctor immediately.
– Do not use your hand to rub the affected eye(s). Instead, use quantities of fresh cold water to
splash it over the affected area to gradually raise temperature of such area above freezing point.
– Obtain proper treatment as soon as possible from a doctor or eye specialist.
 Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.
 Refrigerant must not be handled near where welding or steam cleaning is performed.
 Refrigerant should be kept at a cold and dark place. It should never be stored where a high temper-
ature is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).
 Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.

Handling refrigerant HFC-134a (R-134a)
Always wear goggles to protect your eyes.
Avoid you direct contact to liquid refrigerant.
Do not heat refrigerant container higher than 40 °C (104 °F).
Do not discharge refrigerant into atmosphere.
Do not allow liquid refrigerant to touch bright metals. Refrigerant combined with moisture is corrosive and
will tarnish surfaces of bright metals including chrome. WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
 Do not use your hand to rub affected eye(s). Instead, use quantities of fresh cold water to splash it
over affected area to thus gradually raise its temperature above the freezing point.
 Obtain proper treatment as soon as possible from a doctor or eye specialist.
Should liquid refrigerant HFC-134a (R-134a) get on your skin, such affected part should be treated
in the same manner as when skin is frostbitten or frozen.
