Explanation Of Scheduled Maintenance Services
Below are explanations of the services listed in the maintenance charts.
The proper fluids and lubricants to use are listed in this se\
ction. Make sure whoever services your vehicle uses these. All parts should be \
replaced and all necessary repairs done before you or anyone else drives th\
e vehicle.
1. ENGINE OIL AND OIL FILTER CHANGE* -ALWAYS USE SG OR SG/CE QUALITY, ENERGY CONSERVING
II OILS OF THE PROPER
VISCOSITY. To determine the preferred viscosity oil for your vehicle’s
engine (e.g. SAE 5W-30). See “Engine Oil” in the Index.\

2. CHASSIS LUBRICATION -Lubricate the front suspension, ball joint,
steering linkage, clutch, and transfer case shift linkage, parki\
ng brake
cable guides, propshaft splines, universal joints, brake pedal s\
prings, and
clutch pedal springs at the intervals specified on the proper \
maintenance
schedule, or at every engine oil change, whichever comes first.\
On
vehicles without hydraulic clutches, lubricate the clutch cross \
shaft every
30,000 miles
(50 000 km).
Ball joints should not be lubricated unless their temperature i\
s 10°F
(-12°C) or higher. When the weather is cold, let them war\
m up before
lubricating them or they could be damaged.
Also, be sure to check all the vehicle fluid levels at this \
time.
3. CLUTCH FORK BALL STUD LUBRICATION (4.3L ENGINES ONLY)
-Lubricate the clutch fork ball stud through the fitting on th\
e clutch housing. Lubricant must be added “sparingly” to the fittin\
g, as only
.0066
Ib. (.003 kg) is required to lubricate the ball stud surface\
. Do not add
lubricant more often than the intervals recommended in the Main\
tenance
Schedules. Too much lubricant
will damage the clutch assembly.
4. COOLING SYSTEM SERVICE* -Drain, flush and refill the system wit\
h
new coolant. See “Engine Coolant’’ in the Index for th\
e proper coolant
and mixture to use in your vehicle.
Also inspect the hoses and replace them
if they are cracked, swollen, or
deteriorated. Tighten all hose clamps. Clean the outside of the radiator
and air conditioning condenser. Wash the radiator neck. To ensure proper
operation, pressure test the radiator and cap.

more of these conditions:
In heavy city traffic.
Where the outside temperature regularly reaches 90°F (32°C) or
In hilly or mountainous terrain.
Frequent trailer pulling.
higher.
0 Uses such as taxi, police, delivery or other commercial service\

13. ENGINE ACCESSORY DRIVE BELT INSPECTION*-Inspect belt. Look
for cracks, fraying, wear, and proper tension. Adjust or replac\
e as needed.
14. TIRE AND WHEEL ROTATION AND INSPECTION -For proper wear and maximum tire life, rotate tires at the first
6,000 miles (10 000
kilometers) for Schedule I or 7,500 miles (12 500 kilometers) for
Schedule
II and then every 15,000 miles (25 000 kilometers) thereafter.
Follow the instructions and patterns shown in Section
6. Check tires for
uneven wear or damage.
If irregular or premature wear is apparent,
check wheel alignment. Also, check for damaged wheels. See “\
Tires” in
the Index for more information.
15. DRIVE AXLE SERVICE -Check rear/front axle fluid level and add \
as
needed. Check constant velocity joints and axle seals for leaki\
ng.
Locking differential -Drain fluid at first oil change and refill. Check
fluid level and add as needed at subsequent oil changes. In d\
usty areas
or trailer towing applications, drain fluid at every 15,000 miles
(24
135 kilometers) and refi1l.t
Standard differential -Check fluid level and add as needed at
every oil change. In dusty areas or trailer towing applications\
, drain
fluid every
15,000 miles (24 135 kilometers) and refil1.t
More frequent lubrication may be required for off-road use.
16. BRAKE SYSTEM INSPECTION -When the engine oil is changed,
inspect the lines and hoses for proper hookup, binding, leaks, \
cracks,
chafing, etc. Check the parking brake adjustment, and the fluid\
level in
the master cylinder. A low fluid level can indicate worn disc \
brake pads
which may need to be serviced.t
When the wheels are removed for rotation, inspect disc brake p\
ads for
wear and rotors for surface condition. Also inspect drum brake \
linings for
wear and cracks. Inspect other brake parts, including drums, wh\
eel cylinders, parking brake, etc., at the same time.
Inspect brakes more often if driving habits or conditions resul\
t
in
frequent braking.
tA fluid
loss in these systems may indicate a problem. Have them inspected
and repaired at once.
