SERVICE PROCEDURES (Continued)
2WD—AUTOMATIC TRANSMISSION
Provided the transmission is operable, tow only in
NEUTRAL at speeds not to exceed 30 mph (50
km/h) and distances less than 15 miles (25km/h).
If the vehicle is to be towed more than 15 miles,
the propeller shaft should be disconnected or place
tow dollies under rear wheels.
FOUR-WHEEL-DRIVE VEHICLE TOWING
Chrysler Corporation recommends that a vehicle be
transported on a flat-bed device. A Wheel-lift or
Sling-type device can be used provided all the wheels
are lifted off the ground using tow dollies.
4WD TOWING-REAR END LIFTED
(1) Raise the front of the vehicle off the ground
and install tow dollies under front wheels.
(2) Attach the J-hooks around the axle shaft tube
outboard of the rear springs.
(3) Position and center the sling under and for-
ward of the rear bumper.
(4) Attach safety chains (with pads) at each end of
the rear bumper.
(5) Turn the ignition switch to the OFF position to
unlock the steering wheel.
(6) Secure the steering wheel in straight ahead
position with a clamp device designed for towing.
(7) Shift the transfer case to NEUTRAL.
4WD TOWING-FRONT END LIFTED
To prevent damage to front facia components, use
only a Wheel-Lift type towing device or Flat-Bed
hauling equipment.
If using the wheel-lift towing method, install tow
dollies under rear wheels.
EMERGENCY TOW HOOKS
WARNING: REMAIN AT A SAFE DISTANCE FROM A
VEHICLE THAT IS BEING TOWED VIA ITS TOW
HOOKS. THE TOW STRAPS/CHAINS COULD BREAK
AND CAUSE SERIOUS INJURY.
Some Jeep vehicles are equipped with front emer-
gency tow hooks. The tow hooks should be used for
EMERGENCY purposes only.
CAUTION: DO NOT use emergency tow hooks for
tow truck hook-up or highway towing.
HOISTING RECOMMENDATIONS
FLOOR JACK
When properly positioned, a floor jack can be used
to lift a ZJ vehicle (Fig. 3). Support the vehicle in the
raised position with jack stands at the front and rear
ends of the frame rails.
DRIVE-ON HOIST
FRAME CONTACT HOIST
CAUTION: Do not attempt to lift a vehicle with a
floor jack positioned under:
• An axle tube.
• Aluminum differential.
• A body side sill.
• A steering linkage component.
• A drive shaft.
• The engine or transmission oil pan.
• The fuel tank.
• A front suspension arm.
HOIST
A vehicle can be lifted with:
• A single-post, frame-contact hoist.
• A twin-post, chassis hoist.
• A ramp-type, drive-on hoist.
NOTE: When a frame-contact type hoist is used, ver-
ify that the lifting pads are positioned properly (Fig. 3).
WARNING: THE HOISTING AND JACK LIFTING
POINTS PROVIDED ARE FOR A COMPLETE VEHI-
CLE. WHEN A CHASSIS OR DRIVETRAIN COMPO-
NENT IS REMOVED FROM A VEHICLE, THE
CENTER OF GRAVITY IS ALTERED MAKING SOME
HOISTING CONDITIONS UNSTABLE. PROPERLY
SUPPORT OR SECURE VEHICLE TO HOISTING
DEVICE WHEN THESE CONDITIONS EXIST.
