Replacements
DURING TIRE INSPECTION1. Check all metal surfaces thoroughly while making tire inspections, including areas on inboard side of wheel. Watch for:
^ excessive rust or corrosion build-up.
^ cracks in metal.
^ bent flanges, resulting from road obstructions.
^ loose, missing or damaged lug nuts.
^ bent or stripped lug bolts.
2. Remove damaged wheels.
WARNING: EXCESSIVELY CORRODED OR CRACKED RIMS CAN BE DANGEROUS. DEFLATE TIRES PRIOR TO REMOVAL FROM THE WHEELS.
3. Mark damaged or hazardous areas with chalk so part will be removed from service.
4. Coat wheel pilot area with Disc Brake Caliper Slide Grease D7AZ-19590-A or equivalent meeting Ford specification ESA-M1C172-A. Do not apply grease to lug nut seats or lug bolt.
5. Replace parts as required.
6. Inflate tires only to recommended air pressures.
7. Check the lug nut torque and retighten the lug nuts.
DURING TIRE CHANGES
WARNING:
^ 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.
^ AFTERMARKET AEROSOL TIRE SEALANTS ARE EXTREMELY FLAMMABLE. ALWAYS QUESTION CUSTOMER TO MAKE SURE THESE PRODUCTS HAVE NOT BEEN USED.
^ MAKE SURE THAT REPLACEMENTS ARE MADE WITH THE PROPER SIZES AND TYPES OF WHEELS. FAILURE TO COMPLY WITH THIS WARNING 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 drop well 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.
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.
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.
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.
5. Lubricate the tire side of the rim base just prior to mounting tire.
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.
NOTE: If the tire is to be reinstalled on the same wheel, mark the tire and wheel so they can be reassembled in the same position.
