General Information
Lift and Support Points
NOTE: If you are going to remove heavy componentssuch as suspension or the fuel tank from the rear of thevehicle, first supportthe front ofthe vehicle with tallsafety stands. When substantialweight is removed
from the rear of the vehicle, the center of gravity canchange and cause the vehicle to tip forward on the hoist.
Frame Hoist
1. Position the hoist lift blocks (A), or safety stands,under the vehicle's front support points (B) and rearsupport points (C).
2. Raise the hoist a few inches, and rock the vehiclegently to be sure it is firmly supported.
3. Raise the hoistto full height, and inspectthe liftpoints for solid contact with the lift blocks.
Safety Stands
To support the vehicle on safety stands. use the samesuppon points (B and C) as for a frame hoist, Alwaysuse satety stands when working on or under anyvehicle that is supported only by a jack.
1-8
Floor Jack
1. Set the parking brake.
2. Block the wheels that are not being lifted.
3. When lifting the rear of the vehicle. put thegearshift Iever in reverse.
4. Position the floor jack under the front jacking
bracket (A) or rear jacking bracket (B), center thejacking bracket in the jack lift ptatform (C), and jack
up the vehicle high enough to fit the safety standsunder it.
c
Position the safety stands underthe support points
and adjust them so the vehicle will tevet.
Lower the vehicle onto the stands.

Towing
lf the vehicle needs to be towed, call a professional
towing service. Never tow the vehicle behind another
vehicle with just a rope or chain. lt is very dangerous.
Emergency Towing
There are three popular methods of towing a vehicle.
Flat-bed Equipment The operator loads the vehicle
on the back of a truck. This is the best way of
transporting the vehicle.
To accommodate flat-bed equipment. the vehicle is
equipped with towing hooks (A)and tie down hooks {B).
The towing hook can be used with a winch to pull the
vehicle onto the truck, and the tie down hooks slots can
be used to secure the vehicle to truck.
1-9
Wheel Lift Equipment The tow truck uses two
pivoting arms that go under the tires (front or rear) and
lifts them off the ground. The other two wheels remain
on the ground. This is an acceptable way of towing the
vehicle.
Sling-type Equipment The tow truck uses metal
cables with hooks on the ends. These hooks go around
parts of the frame or suspension and the cables lift that
end of the vehicle off the ground. The vehicle's
suspension and body can be seriously damaged if this
method of towing is attemPted.
lf the vehicle cannot be transported by flat-bed, it
should be towed with the front wheels off the ground lf
due to damage, the vehicle must be towed with the
front wheels on the ground, do the following:
. Release the parking brake.. shift the transmission in Neutral.
It is best to tow the vehicle no farther than 50 miles (80
km), and keep the speed below 35 mph (55 km/h).
. lmproper towing preparation will damage the
transmission. Follow the above procedure exactly. lf
you cannot shift the transmission, the vehicle must
be transDorted on a flat-bed.. Trying to lift or tow the vehicle by the bumpers will
cause serious damage, The bumpers are not
designed to support the vehicle's weight.

General Information
Parts Marking
To deter vehicle theft, certain major components are marked with the vehicle identification number (VlN). Originalparts have self-adhesive labels. Replacement body parts have generic self-adhesive labels. The original engrne ortransmission VIN plate is transferred lo a replacement engine or transmission and attached with break-off bolts.
NOTE: Be careful not to damage the parts marking labels during body repair. Mask the labels before repairing the part.
