Towing the Vehicle with the Rear Wheels Suspended
Note:To avoid damage to the cab roof or air deflector when towing the
vehicle backward (rear wheels suspended), the air deflector must be
removed.
Whenever possible, it is preferable to tow a disabled vehicle from the
rear by raising the rear of the chassis. When towing a vehicle with the
rear of the chassis suspended, the front wheels must be locked in the
straight-ahead position.
Vehicles equipped with a manual transmission must have at least 1.0 pint
(0.5 liter) of transmission fluid drained from the case. This prevents the
transmission fluid from entering the clutch housing and saturating the
clutch discs. Make sure that the transmission fluid is replaced before the
vehicle is returned to service.

axle wheels on the ground, it is necessary to remove the axle shafts
before the vehicle is towed.

Removing Axle Shafts before Towing
1. Shift the main differential to the unlocked (disengaged) position; the
differential lock light turns off.
2. Remove the capscrews and washers or stud nuts and washers from
flanges of both axle shafts.
3. Loosen the tapered dowels in the flanges of both axle shafts by
holding a 1
1 2inch diameter brass drift or hammer against the axle
shaft center and hitting it with a five or six pound hammer.Note:Do
not use a chisel or wedge to loosen the axle shafts and dowels. Use
of a chisel or wedge can damage the hub, axle shafts and oil seals.
4. Remove the tapered dowels and both axle shafts from the axle
assembly.
5. Assemble a cover over openings of both wheel ends to prevent loss of
lubricant and keep dirt away from the wheel bearing cavities.
Note:One of the axle shafts has two sets of splines. One set to engage
with the differential side gear and one set to engage with the shift collar
for the differential lock. It may be necessary to rotate the shaft slightly
to align the gear spline teeth with the shift collar teeth in order to
remove the axle shaft.
Installing the Axle Shafts
1. Remove the covers from the wheel ends.
2. Shift the differential lock to the unlocked (disengaged) position.
3. Install the axle shafts.
•Place the gaskets on the wheel hub studs.
•Push the right-hand axle shaft and gasket into the wheel end and
housing until the shaft stops against the differential shift collar.
•Push down and in on the axle shaft flange and rotate the shaft
until the splines of the shaft and shift collar are engaged.
•Push the axle shaft further into the housing until the shaft stops
against the differential side gear.
•Push down on the axle shaft flange and rotate the shaft until the
splines of the shaft and side gear are engaged.
•Push the axle shaft completely into the housing until the axle
shaft flange and the gasket are flush against the wheel hub.
•Install the left-hand axle shaft and gasket into the wheel end.
4. If tapered dowels are required, install them at each stud and into the
flange of the axle shaft. Use a punch or drift and hammer, if needed.
5. Install the fasteners and tighten to correct torque value. See the
Workshop Manual.

Supporting Your Vehicle for Service
WARNING:Do not use a jack when working under a vehicle. It
may give way, causing the vehicle to fall and result in property
damage, personal injury or death. Always use floor stands to support
the vehicle.
Prepare the vehicle for service repairs by doing the following:
1. Park the vehicle on a level, concrete floor.
2. Set the parking brake and block the wheels to prevent the vehicle
from moving.
3. Select a jack with a rated capacity sufficient to lift and hold up the
vehicle.
4. Raise the vehicle with the jack applied to the axle(s). DO NOT use
the bumper as a lifting point.
5. Support the vehicle with floor stands under the axle(s). If the axle or
the suspension is being serviced, support the vehicle with floor
stands under the frame side-members, preferably between the axles.
Frame and Tow Hooks
Your vehicle’s chassis is manufactured with frame rails of either HSLA
steel or heat-treated steel. Each must be handled in a specific manner to
make sure maximum service life. Consult the service manual or your
dealer before attempting frame repair or modification.
It is important, particularly on vehicles where the tow hooks are used
frequently, to inspect the front and rear tow hooks for damage or a loose
mounting.
OPENING AND CLOSING THE HOOD
WARNING:The parking brake must be fully set before opening
the hood or possible personal injury may occur.
WARNING:To reduce the risk of the possibility of personal
injury, never stand beneath the hood when it is being raised or
lowered.
WARNING:If you must leave the engine running while checking
under the hood, do not allow any loose clothing, jewelry, hair or
other items to get near moving engine components or possible personal
injury may occur.

CHANGING THE WIPER BLADES
1. To remove the wiper blade, pull
the wiper arm away from the
vehicle. Pry open the lock cover
(A) with your thumb to release
the blade.
2. Press the retaining clip to
disengage the wiper blade, then
pull the wiper blade down (C)
toward the windshield to remove
it from the arm.
3. To install the new wiper blade,
insert the wiper blade into the
wiper arm hook (B).
4. While holding the wiper arm,
push the wiper blade up and
away from the windshield.
5. Close the lock cover.
Replace wiper blades at least once per year for optimum performance.
Poor wiper quality can be improved by cleaning the wiper blades and the
windshield. SeeCleaning the windows and wiper bladesin theVehicle
Carechapter.
To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.
AIR FILTER CHECK
Diesel Engine
See your engine operator’s manual for information on the engine air
filter.
Gasoline Engine
Note:Do not start your engine with the air cleaner removed and do not
remove it while the engine is running.
