LUBRICATION
AND
MAINTENANCE
• A vehicle equipped with SAE approved sling-type
towing equipment can be used (Fig. 10). However,
many vehicles are equipped with air dams, spoilers, and/or ground effect panels. In this case a wheel-lift
towing vehicle or a flat-bed hauling vehicle is recom mended (Fig. 10). If a flat bed device is used, the ap
proach angle should not exceed 15 degrees.
GROUND CLEARANCE The lifted wheels of the disabled vehicle should be
a minimum of 10 cm (4 in.) off the ground. Make
sure there is enough clearance at the opposite end.
This is critical when towing over rough terrain. If necessary, the rear ground clearance can be increased by removing the wheels from the lifted end
and then towing with the lifted end closer to the
ground. If the rear wheels are removed, secure the
brake drums. A 20 cm (8 in.) ground clearance must
be maintained between brake drums or rotors and the ground.
SAFETY PRECAUTIONS The following safety precautions must be consid
ered when preparing for and during a vehicle towing operation:
• Remove exhaust pipe tips that interfere with the
tow sling and crossbar • Padding should be placed between the tow sling/
crossbar and any painted surfaces
• If the vehicle is damaged, secure the loose and pro
truding parts
• Always use a safety chain system that is indepen dent of the lifting and towing equipment
• When placing tow hooks on the rear axle, position them so they do not damage the brake tubing or
hoses
• Do not allow any of the towing equipment to con
tact the fuel tank
• Do not tow the vehicle by connecting to the front
or rear shock absorbers
• The operator should not go under a vehicle while
it is lifted by the towing equipment. The vehicle
should first be supported by safety stands
• Do not allow passengers in a vehicle being towed
• Observe all state and local laws involving warning signals, night illumination, speed, etc.
• Do not exceed a towing speed of 48 km/h (30 mph)
• Avoid towing distances of more than 24 km (15
miles) whenever possible • Do not attach tow chains or a tow sling to a
bumper, the steering linkage, the universal joints, or a drive shaft
REAR-END RAISED TOWING It is recommended that the rear-end raised towing
method be used. Vehicles can be towed with the front
wheels on the ground for extended distances at speeds not exceeding 48 km/h (30 mph) (Fig. 11). (1) Attach the J-hooks around the axle shaft tubes
outboard of the rear springs. (2) Position and center the sling under and for
ward of the rear bumper. (3) Attach safety chains (with pads) at each end of
the rear bumper.
(4) Turn the ignition switch to the OFF position to
unlock the steering wheel. (5) Clamp the steering wheel with the front wheels
in the straight ahead position.
CAUTION:
Do not use the steering
column
lock
to
secure
front
wheel
in the straight-ahead
position.
(6) Shift the transmission to NEUTRAL.

FRONT'END RAISED TOWING If a vehicle cannot be towed from the rear, the
front-end raised towing method normally can be
used (Fig. 12). (1) Center the sling with the bumper and position
it at the frame front crossmember.
CAUTION:
Use tow
chains
with
J-hooks

(2) Route the J-hooks and tow chains over the
steering linkage outboard of the coil spring.
(3) Attach the J-hooks to the outer end of the
lower suspension arms.
(4) Raise the vehicle.
(5.) Attach the safety chains to the disabled vehicle
at the frame rails.
Vehicles equipped with a MANUAL TRANSMIS
