2003 FORD MUSTANG warning

GENERAL PROCEDURES
Powertrain/Drivetrain Mount Neutralizing
WARNING: The electrical power to the air suspension system must be shut off prior to
hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off
the air suspension switch. Failure to do so can result in unexpected inflation or deflation of the
air springs, which can result in shifting of the vehicle during these operations.
1. Raise and support the vehicle.
2. Loosen, but do not remove, the powertrain/drivetrain mount fasteners.
3. Lower the vehicle.
4. CAUTION: Do not twist or strain the powertrain/drivetrain mounts.
Move the vehicle in forward and reverse 0.6- 1.2 meters (2-4 ft).
5. Raise and support the vehicle.
6. Tighten the powertrain/drivetrain mount fasteners.
7. Lower the vehicle.
8. Test the system for normal operation.

GENERAL PROCEDURES
Exhaust System Neutralizing
WARNING: Exhaust gases contain carbon monoxide, which is harmful to health and
potentially lethal. Repair exhaust system leaks immediately. Never operate the engine in an
enclosed area.
WARNING: Exhaust system components are hot.
NOTE: Neutralize the exhaust system to relieve strain on mounts which can be sufficiently bound up to
transmit vibration as if grounded.
1. WARNING: The electrical power to the air suspension system must be shut off prior
to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by
turning off the air suspension switch. Failure to do so can result in unexpected inflation
or deflation of the air springs, which can result in shifting of the vehicle during these
operations.
CAUTION: Make sure the system is warmed up to normal operating temperature, as
thermal expansion can be the cause of a strain problem.
Raise and support the vehicle.
2. Loosen all exhaust hanger attachments and reposition the hangers until they hang free and straight.
3. Loosen all exhaust flange joints.
4. Place a stand to support the muffler parallel to the vehicle frame with the muffler pipe bracket free of stress.
5. Tighten the muffler connection.
6. Tighten all the exhaust hanger clamps and flanges (tighten the exhaust manifold flange joint last).
zVerify there is adequate clearance to prevent grounding at any point in the system. Make
sure that the catalytic converter and heat shield do not contact the frame rails.
z After neutralization, the rubber in the exhaust hangers should show some flexibility when
movement is applied to the exhaust system.
z With the exhaust system installed securely and cooled, the rear hanger should be angled
forward.
7. Lower the vehicle.
8. Test the exhaust system for normal operation.

GENERAL PROCEDURES
Wheel Bearing Check
1. WARNING: The electrical power to the air suspension system must be shut off prior
to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by
turning off the air suspension switch. Failure to do so can result in unexpected inflation
or deflation of the air springs, which can result in shifting of the vehicle during these
operations.
Raise the vehicle until the front tires are off the floor.
zMake sure the wheels are in a straight forward position.
2. NOTE: Make sure the wheel rotates freely and that the brake pads are retraced sufficiently to
allow free movement of the tire and wheel assembly.
Spin the tire by hand to check the wheel bearings for roughness.
3. Grip each front tire at the top and bottom and move the wheel inward and outward while lifting the weight of the tire off the front wheel bearing.
4. If the tire and wheel (hub) is loose on the spindle, does not rotate freely, or has a rough feeling when spun, carry out one of the following:
1. On vehicles with inner and outer bearings, inspect the bearings and cups for wear or damage. Adjust or install new bearings and cups as necessary.
2. On vehicles with one sealed bearing, install a new wheel hub.

WARNING: All vehicles are equipped with gas pressurized shock absorbers which
will extend unassisted. Do not apply heat or flame to the shock absorbers during
removal or component servicing. Failure to follow these instructions can result in
personal injury.
Disconnect the front shock absorber (18124) from the spindle. 1. Remove and discard the nuts and bolts.
2. Disconnect the shock absorber.
13. Remove the spindle. 1. Remove and discard the nut.
2. Remove the spindle. Klj . 3 ba

Removal
WARNING: All vehicles are equipped with gas pressurized shock absorbers which will
extend unassisted. Do not apply heat or flame to the shock absorbers during removal or
component servicing. Failure to follow these instructions can result in personal injury.
CAUTION: Suspension fasteners are critical parts because they affect performance of vital
components and systems and their failure can result in major service expense. A new part with
the same part number or an equivalent part must be installed, if installation is necessary. Do
not use a part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to ensure proper retention of these parts.
1. Raise the vehicle on a hoist. For additional information, refer to Section 100 - 02 .
2. Remove the wheel and tire assembly. For additional information, refer to Section 204 - 04 .
3. Remove the front brake disc. For additional information, refer to Section 206 - 03 .
4. Remove the bolt and the ABS sensor.
5. Unclip the ABS sensor wire from the bracket.
6. Remove the nut and the ABS sensor wire bracket.

components and systems and their failure can result in major service expense. A new part with
the same part number must be installed if installation becomes necessary. If substitution is
necessary, the part must be of the same finish and property class. Torque values must be used
as specified during reassembly to make sure of correct retention of these parts.

DESCRIPTION AND OPERATION
Safety Precautions
WARNING: Never run the engine with one wheel off the ground, for example, when
changing a tire. The wheel(s) resting on the ground could cause the vehicle to move.
WARNING: The tire and wheel must always be correctly matched. It is very important to
determine the size of each component before any assembly operations commence. Failure to
adhere to these instructions can result in an explosive separation and cause serious bodily
injury or death.
WARNING: Aftermarket aerosol tire sealants are extremely flammable. Always question
the customer to make sure these products have not been used.
WARNING: Aftermarket wheel assemblies may not be compatible with the vehicle. Use of
incompatible wheel assemblies can result in equipment failure and possible injury. Use only
approved wheel assemblies.
WARNING: Use only wheels and wheel nuts that have been designed for current model
year Ford trucks. Aftermarket wheels or wheel nuts may not fit or function correctly, and can
cause personal injury or damage the vehicle.
WARNING: Always wear safety goggles or a face shield when performing any work with
tire and wheel assemblies.
CAUTION: Do not clean aluminum wheels with steel wool, abrasive- type cleaners or
strong detergents. Use Custom Bright Metal Cleaner 8A-19522- A or equivalent meeting Ford
specifications ESR- M5B194-B.
CAUTION: Reduce the air pressure as much as possible by pushing the valve core
plunger in prior to removing the valve core. Avoid working in a position in which the face or
body is directly over a tire in which there is pressure.
When performing any inspection or repair procedures on wheels (1007/1015) and tires, follow the
preceding safety precautions. SECTION 204-
