Downloaded from www.Manualslib.com manuals search engine 13. TIRE AND WHEEL ROTATION AN- INSPECTION -For proper wear
and maximum tire life, rotate tires at the first
6,000 miles (1 0 000
kilometers) for Schedule I or 7,500 miles (12 500 kilometers) for
Schedule
II and then every 7,500 miles (12 500 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.

DRIVE AXLE SERVICE -Check readfront 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 application\
s, drain
fluid every
15,000 miles (24 135 kilometers) and refi1l.t

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$
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 result in
frequent braking.
tA fluid loss in these systems may indicate a problem. Have them inspected
and repaired at once.
