2003 FORD MUSTANG jacking

DESCRIPTION AND OPERATION
Jacking
WARNING: Never run the engine with one wheel off the ground, such as when changing a
tire. The wheel still on the ground could cause the vehicle to move.
CAUTION: The jack (17080) provided with the vehicle is intended to be used in an
emergency for changing a deflated tire. To avoid damage to the vehicle, never use the jack to
lift the vehicle for any other purpose. Refer to the Owner Guide when using the jack supplied
with the vehicle.
CAUTION: Under no circumstances should the vehicle ever be lifted by the suspension
arm brackets, rear stabilizer or differential housing or convertible cross brace. Severe damage
to the vehicle could result.
CAUTION: Do not attempt to use jack pressure on either the front bumper (17757) or the
rear bumper (17906) of any vehicle. Damage to the bumper covers will occur.
Lift the vehicle using the Jacking Points procedure in this section.
Jacking Points
To lift the front or either side of the front end, position the floor jack under the front frame lift points. SECTION 100-

DESCRIPTION AND OPERATION
Lifting
CAUTION: Do not allow the lift adapters to contact the steering linkage, suspension arms,
stabilizer arms, or to compress the lower suspension arm stabilizer bar insulator (5493).
Damage to the suspension, exhaust and steering linkage components may occur if care is not
exercised when positioning the hoist adapters prior to lifting the vehicle.
CAUTION: Never use the differential housing as a lift point. Damage to the differential
housing and cover may occur.
CAUTION: Do not lift vehicle on rocker panel pinch flange or convertible cross brace.
Body damage may occur.
Lift the vehicle using the Lifting Points procedure in this section.
Lifting Points—Drive On Lift
CAUTION: To prevent possible damage to the underbody, do not drive the vehicle onto
the drive on lift without first checking for possible interference.
Check for interference between the upright flanges of the hoist rails and the underbody.
If an interference exists, modify the hoist flanges or build up the approach ramps as necessary to
provide clearance. Lifting Points — Frame Contact Lift, Single Post Lift, Two Post Lift SECTION 100-

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.
