Body Lubrication

Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points and
rollers, liftgate, tailgate, decklid, sliding doors
and hood hinges, should be lubricated periodi-
cally with a lithium based grease, such as Mopar
Spray White Lube to assure quiet, easy opera-
tion and to protect against rust and wear. Prior to
the application of any lubricant, the parts con-
cerned should be wiped clean to remove dust
and grit; after lubricating excess oil and grease
should be removed. Particular attention should
also be given to hood latching components to
ensure proper function. When performing other
underhood services, the hood latch, release
mechanism and safety catch should be cleaned
and lubricated.
The external lock cylinders should be lubricated
twice a year, preferably in the Fall and Spring.
Apply a small amount of a high quality lubricant,
such as Mopar Lock Cylinder Lubricant directly
into the lock cylinder.

Windshield Wiper Blades

Clean the rubber edges of the wiper blades and
the windshield periodically with a sponge or soft
cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using the
wipers to remove salt or dirt from a dry wind-
shield.
Avoid using the wiper blades to remove frost or
ice from the windshield. Keep the blade rubber
out of contact with petroleum products such as
engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use.
Poor performance of blades may be present
with chattering, marks, water lines or wet spots.
If any of these conditions are present, clean the
wiper blades or replace as necessary.
The wiper blades and wiper arms should be
inspected periodically, not just when wiper per-
formance problems are experienced. This in-
spection should include the following points:
• Wear or uneven edges
• Foreign material
• Hardening or cracking
• Deformation or fatigue
If a wiper blade or wiper arm is damaged,
replace the affected wiper arm or blade with a
new unit. Do not attempt to repair a wiper arm or
blade that is damaged.

CAUTION!
Do not allow the wiper arm to spring back
against the glass without the wiper blade in
place or the glass may be damaged.
