Mustang GT V8-4.6L SOHC VIN X (1998)
WARNING: EXCESSIVELY CORRODED OR CRACKED RIMS CAN BE DANGEROUS. DEFLATE TIRES PRIOR TO THE
REMOVAL FROM THE WHEELS.
2. Remove damaged rims or wheels.
3. Mark damaged or hazardous areas with chalk so that part will be removed from service.
4. Coat wheel pilot area with Silicone Brake Caliper Grease and Dielectric Compound D7AZ-19A331-A or equivalent meeting Ford specification
ESE-M1C171-A. Do not apply grease to lug nut seats or lug bolts.
5. Replace parts as required.
6. Inflate tires only to recommended air pressures.
7. Check the wheel hub bolt nut torque and retighten the lug nuts.
During Tire Changes
WARNING:
-
AFTER MARKET AEROSOL TIRE SEALANTS ARE EXTREMELY FLAMMABLE. ALWAYS QUESTION CUSTOMER TO
MAKE SURE THESE PRODUCTS HAVE NOT BEEN USED.
-
ALLOYS OR METAL SURFACES WITH CRACKS ARE VERY DANGEROUS. THESE COMPONENTS COULD FAIL
WITHOUT WARNING DURING INFLATION OR LATER ON THE VEHICLE CAUSING LOSS OF CONTROL OR PERSONAL
INJURY. DESTROY ALL PARTS THAT ARE CRACKED.
CAUTION: Make sure replacements are made with the proper sizes and types of wheels. Failure to comply may result in equipment failure and
possible injury.
1. Check all metal surfaces. Watch particularly for the following items:
-
Cracks in the rim bead seat or dropwell radii areas, these are caused by deep rim tool marks, overloading and overinflating tires or using larger
than recommended tire sizes.
-
Cracks in the wheel disc, between the stud holes or hand holes; these are caused by loose lug nuts, improper installation procedures or the use
of incorrect sizes or types of attaching parts.
2. Replace the parts as necessary.
3. Thoroughly remove rust, dirt and other foreign materials from all surfaces. Hand or electric wire brushes, sand blasting or chemical baths may be
used. Bead seat areas of rim should be free of rust and rubber deposits. This is especially important for drop-center tubeless rims because the bead
seat is the air-sealing element.
4. Paint rim by brush or spray with a fast-drying metal primer. Surfaces should be clean and dry prior to painting. Make sure bare metal areas on the
outside or tire side of rim are covered. This is especially important on drop-center tubeless rims because warm and sometimes moist air is in
constant contact with the metal surface on the tire side of the rim.
5. Lubricate the tire side of the rim base just prior to mounting tire.
NOTE: Avoid the use of any lubricant which contains water or solvent that is injurious to rubber such as WD40. A combination lubricant and
rust-preventive compound is preferable such as a rubber lubricant meeting Ford specification ESA-M1B6-A. This protective measure is of
particular importance with drop-center tubeless rims as the air in the tire is contained by the tire-side rim surface.
6. Inflate tire to recommended air pressure.
CAUTION: When mounting a tire on a wheel, do not inflate to more than 276 kPa (40 psi); then deflate tire.
Road Test
A tire vibration diagnostic procedure always begins with a road test. The test and customer interview (if available) will provide much of the
information needed to find the source of a vibration.
During the road test, drive the vehicle on a road that is smooth and free of undulations. If vibration is apparent, note and record the following:
-
The speed at which the vibration occurs
-
What type of vibration occurs in each speed range
+
mechanical or audible
-
How the vibration is affected by changes in vehicle speed, engine speed, and engine torque
-
Type of vibration sensitivity
+
torque sensitive, vehicle speed sensitive, or engine speed sensitive
The following explanations help isolate the source of the vibration:
Torque Sensitive
This means the condition can be improved or made worse by accelerating, decelerating, coasting, maintaining a steady vehicle speed or applying
engine torque.
