2003 FORD MUSTANG tow

GENERAL PROCEDURES
Brake Disc Machining
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: Do not install brake discs that are less than the minimum thickness specified.
Do not machine a brake disc below the minimum thickness specification.
1. Check wheel bearing end- play and correct as necessary.
2. NOTE: Begin at the front of the vehicle unless the vibration has been isolated to the rear.
Remove the tire and wheel assembly.
3. Remove the brake caliper and the brake caliper anchor plate. Refer to the appropriate section in Group 206 for the procedure.
4. Inspect the brake linings. Install new brake linings if below specification. For additional information, refer to the appropriate brake section.
5. Measure and record the brake disc thickness. Install a new brake disc if the thickness after machining will be at or below specification. The specification is molded into the brake disc.
zDo not machine a new brake disc.

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.

GENERAL PROCEDURES
Camber and Caster Adjustment —
Front
All vehicles 1. Remove the rivet. Loosen the nuts and bolt.
Vehicles requiring camber adjustment 2. Move the front suspension camber adjusting plate (3B391) to the required camber setting.
Vehicles requiring caster adjustment 3. NOTE: If caster adjustment is necessary to resolve a pull, or out of specification cross- caster
split, then slotting the shock tower at the front shock absorber (18124) upper mounting point is
an acceptable method. This procedure should not be routinely performed with all alignments
and only after all other possible sources have been inspected and corrected as necessary.
Determine the amount of caster adjustment needed.
zIf no more than 0.6 degree is needed, only one shock tower needs to be slotted.
4. Mark the camber position of the front suspension camber adjusting plate (3B391).

5. Remove the nuts, bolt and the front suspension camber adjusting plate.
6. Raise the front end. Position the strut and spring assembly out of the way. For additional
information, refer to Section 100 - 02 .
7. Cut slots perpendicular to the existing camber adjustment slots. zMoving the top of the front shock absorber toward the rear of the vehicle will increase the
caster reading for that side.
z Each millimeter of adjustment should yield approximately 0.12 degree of caster change.
z Do not cut slots any longer than 5 mm (0.2 in.) in any direction.
z Remove any burrs.
z Clean and paint any exposed metal.
8. Position the strut and spring assembly. Lower the front end.
9. Install the front suspension camber adjustment plate, bolt and nuts. Hand tighten the bolt and nuts. Klj . 2 ba

5.
CAUTION: Always install the bearing caps in their identical locations and positions.
NOTE: Apply pressure toward the left side to make sure the left differential bearing cup seats
correctly.
Install the left bearing cap and loosely install the bolts.
6. Install progressively larger differential bearing shims on the right side until the largest shim selected is installed by hand. Klj . 7 ba
