							Always follow any instruction labels on the vehicle, especially if they differ from another source
It is very important to be careful about running the engine, on vehicles equipped with limited slip differentials,
while the vehicle is up on a jack. This is because if the drive train is engaged, power is transmitted to the
wheel with the best traction and the vehicle will drive off the jack, resulting in possible damage or injury.
Lift the front by positioning the jack under the lower front shock absorber mount HOW TO USE THIS BOOK

							Always safely support the vehicle on jackstands, either under the suspension member or the
frame
Jack the truck from under the axles, radius arms, or spring hangers and the frame. Be sure and block the
diagonally opposite wheel to prevent the vehicle from moving. Place jackstands under the vehicle at the points
mentioned above when you are going to work under the vehicle.
Lift the rear by positioning the jack under the rear spring mount on the axle HOW TO USE THIS BOOK

							The jackstand can be positioned under the spring-to-frame mount
CAUTION
On models equipped with an under chassis mounted spare tire, remove the tire, wheel or tire carrier from the
vehicle before it is placed in a high lift position in order to avoid sudden weight release from the chassis.
When raising the vehicle on a hoist, position the front end adapters under the center of the lower suspension
arm or the spring supports as near to the wheels as practical. The rear hoist adapters should be placed under
the spring mounting pads or the rear axle housing. Be careful not to touch the rear shock absorber mounting
brackets.

DISTRIBUTOR IGNITION SYSTEM
General Information
Only the 1991-92 2.9L and the 1991-94 3.0L engines are equipped with the distributor ignition system. The
distributor ignition system consists of the following components:
Ignition Control Module (ICM)
· 
Distributor
· 
Camshaft Position (CMP) sensor
· 
Ignition coil
· 
The distributor ignition system designed by Ford has two distinct configurations. The first configuration is
known as the distributor mounted system, because the ICM is mounted directly on the distributor housing.
The second configuration is known as a remote mount system, since the ICM is mounted on the front fender
apron.
The distributor used by this system is sealed and houses the CMP sensor. The distributor does not utilize
vacuum or centrifugal advance mechanisms; the ignition timing is automatically controlled by the Powertrain
Control Module (PCM) and the ICM.
Ford calls this electronic ignition the Thick Film Integrated-IV (TFI-IV) ignition system. The TFI module is
also known as the Ignition Control Module (ICM) which reports engine position and rpm to the PCM. The
PCM then determines the proper spark timing and advance, and returns a reference signal to tell the TFI
module to switch the coil, thereby by creating a spark. The PCM used on these vehicles is referred to by Ford
as the Electronic Engine Control-IV (EEC-IV) module.
