9. Air Cleaner Filter Replacement': -
Replace every 30,000 miles (50 000
km) or more often under dusty
conditions. Ask your dealer for the
proper replacement intervals for your
driving conditions.
10. Fuel Tank, Cap and Lines
Inspection*t
- Inspect fuel tank,
cap and lines (including fuel rails
and injection assembly) for damage
or leaks. Inspect fuel cap gasket for
an even filler neck imprint or any
damage. Replace parts as needed.
1 1. Positive Crankcase Ventilation
(PCV) System 1nspection':t
-
Inspect the system for proper
function. Replace any worn, plugged
or collapsed hoses and seals.
Replace valve only if necessary.
12. Fuel Filter Replacement'$t -
Replace the fuel filter every 30,000
miles (50 000 ltrn), or sooner if
clogged.
13. Engine Timing and Distributor Check':'t
- Adjust the timing to
the underhood label specifications.
Inspect the inside and outside of the
distributor cap and rotor for craclts, carbon tracking and corrosion.
Clean or replace
as needed.
14. Differential (Axle) Service-Check
rear/front differential fluid level and
add as needed. Check constant
velocity joints and axle seals for
leaking.
Locking Rear Differential -Drain
fluid at first engine oil change and
refill. Check fluid level and add as
needed at subsequent oil changes. In
dusty areas, or trailer towing
applications, drain fluid at every
15,000 miles (25 000 ltm) and refill.
More frequent lubrication may be
required during heavy-duty or off-
road use. A fluid loss in this system
may indicate
a problem. Have it
inspected and repaired at once.
15. Brake Systems Inspection-When
the engine oil is changed, inspect
the lines and hoses for proper
hookup, binding, leaks, craclts,
chafing, etc. Check the parking
brake adjustment and the fluid level
in the master cylinder. A low brake
fluid level can indicate worn disc
brake pads which may need to be
serviced.
A fluid loss in this system may indicate a problem. See
the
Index under Brake System Warning
Light. 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
craclts. Inspect other brake parts,
including drums, wheel cylinders,
calipers, parking brake, etc. at the
same time.
You may need to have your brakes
inspected more often
if your driving
habits or conditions result in
frequent braking.
16. Transfer Case Fluid Change -In
heavy or frequent trailer towing
applications, drain fluid and refill
every
30,000 miles (50 000 ltm).
