11-4 Service and Maintenance
.Lubricate the front suspension,
steering linkage, and parking
brake cable guides. Control arm
ball joints on 2500/3500 series
vehicles require lubrication but
should not be lubricated unless
their temperature is−12°C
(10°F) or higher, or they could
be damaged. Control arm ball
joints on 1500 series vehicles
are maintenance‐free. Vehicles
used under severe commercial
operating conditions require
lubrication on a regular basis
every 5 000 km/3,000 miles..Body hinges and latches, key
lock cylinders, folding seat
hardware, and tailgate hinges,
linkage, and handle pivot points
lubrication. See Recommended
Fluids and Lubricants
on
page 11‑8. More frequent
lubrication may be required
when the vehicle is exposed to a
corrosive environment. Applying
silicone grease on weatherstrips
with a clean cloth makes them
last longer, seal better, and not
stick or squeak.
.Restraint system component
check. See Safety System
Check on page 3‑29.
.Fuel system inspection for

.Four‐wheel drive only: Transfer
case fluid change (extreme duty
service) for vehicles mainly
driven off‐road in four‐wheel
drive. Vehicles used for farming,
mining, forestry, Department of
Natural Resources (DNR), and
snow plowing occupations meet
this definition. Check vent hose
at transfer case for kinks and
proper installation. Check to be
sure vent hose is unobstructed,
clear, and free of debris. During
any maintenance, if a power
washer is used to clean mud
and dirt from the underbody,
care should be taken to not
directly spray the transfer case
output seals. High pressure
water can overcome the seals
and contaminate the transfer
case fluid. Contaminated fluid
will decrease the life of the
transfer case and should be
replaced.First Engine Oil Change After
