CAUTION!
•Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage
your vehicle.
•During the first 500 miles (805 km) of trailer
towing, limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR,
or GCWR, ratings.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.

3. When changing a front wheel, place the jack under the
frame rail behind the wheel. Locate the jack as far
forward as possible on the straight part of the frame
(prior to inboard transition. Operate the jack using the
jack drive tube and the wheel wrench - the tube exten-
sion, may be used but is not required.When changing a rear wheel, assemble the jack drive
tube to the jack and connect the drive tube to the
extension tube. Place the jack under the axle as close to
the tire as posssible with the drive tubes extending to the
rear. Connect the jack tube extension and wheel wrench.

Axles
Refer to Fluids, Lubricants and Genuine Parts for correct
fluid type.
The manufacturer does not recommend regularly sched-
uled oil changes for axles in vehicles whose operation is
classified as normal truck service.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Rear Axle
Rear Axle fluid levels should be 1/4(6.4 mm) +/- 1/4“
below the fill hole for 8 1/4, and 9 1/4axles.
Front Axle
Front Axle fluid level should be 1/4” (6.4 mm) below the
level of the fill hole.
Selection of Lubricating Grease
The National Lubricating Grease Institute (NLGI) has
developed a symbol (Certification Mark) to aid the
vehicle owner in the proper selection of grease for chassis
components. This symbol, an example shown below, is
located on the grease container and identifies the appli-
cation and quality of the grease.
There are two groups
identified, those for wheel
bearings (Letter “G”) and
those for chassis (Letter
“L”) lubrication. Perfor-
mance categories within
these groups result in dual
letter designations for
each group. The letter des-
ignations shown in the ex-
ample are the highest
quality level available and when combined as shown can
