Scheduled Maintenance Services
13.
ENGINE ACCESSORY DRIVE BELT
INSPECTION*-Inspect belt. Look
for cracks,
fraying, wear, and proper
tension. Adjust or replace 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
leaking.
Locking differential
-Drain
fluid at
first oil change and refill. Check
fluid
level and add as needed at subsequent oil changes.
In dusty
areas
or
trailertowingapplications,drainfluidatevery15,000miles
(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 pads
for
wear and rotors
for surface condition. Also
inspect drum brake
linings
for
wear and cracks.
Inspect other brake parts,
including drums, wheel
cylinders, parking brake, etc., at
the same
time.
Inspect brakes more often
if driving habits or conditions result
in
frequent braking.
t A fluid
loss
in
these systems may
indicate a problem. Have
them
inspected
and repaired at once.
