GENERAL PROCEDURES
Wheel Leaks
WARNING: Wheel repairs that use welding or peening are not approved. An inner tube is
not an acceptable repair for leaking wheels or tires.
If the air pressure in a tire mounted on an aluminum wheel is found to be low, perform the
following procedure before considering installation of a new wheel.
1. Remove the tire and wheel assembly, and inspect the wheel for structural damage. If none exists, go to Step 2. If the wheel is damaged, install a new wheel.
2. With the tire mounted on the wheel, locate the air leak using a water bath or equivalent method, and mark the location. Check the complete wheel for possible additional leaks. When leaks are
marked, dismount the tire marking valve location on the tire for correct indexing.
3. On the tire side of the wheel, thoroughly clean the leaking area with an appropriate choke cleaner or use sandpaper of approximately 80- grit to remove all contamination. Using the
sandpaper, score the surface of the leaking area to improve adhesion of the sealer. If the valve
stem is close to the area, remove it.
4. Use a clean cloth to remove all cleaner or sanding dust.
5. NOTE: Do not use a torch containing oxyacetylene.
Heat the prepared area with a Heat Gun or a propane torch until aluminum wheel repair
compound flows. Apply the hot melt material over the prepared area using a liberal flow and
wiping action. Repair is most effective when heat is applied to the brake side of the rim, and the
sealer is melted by heat in the metal.
6. Apply only enough heat to melt the sealer, then remove the heat source. After repairing the leak, allow the wheel to cool until it can be handled safety.
7. CAUTION: Use caution when mounting the tire so as not to damage the sealer.
Index and assemble the tire and wheel. Inflate the tire to the recommended pressure as
indicated on the tire pressure decal.
8. Repeat Step 2 to verify repair.
9. When the repair is completed, balance the assembly and install it on the vehicle.

REMOVAL AND INSTALLATION
Wheel And Tire
Removal
1. CAUTION: Do not use heat to loosen a seized wheel nut (1012). Heat can damage
the wheel and wheel bearings.
NOTE: To avoid damage or scratching to the center cap, place facing up when removed.
Loosen the wheel nuts. 1. NOTE: To avoid wheel damage, do not twist wrench when removing center cap.
Remove the center cap, if equipped.
2. Loosen, but do not remove, the wheel nuts.
2. CAUTION: Never use the differential housing as a lifting point.
Raise the vehicle until the tire clears the ground. For additional information, refer to Section 100 - 02 .
3. CAUTION: Do not use heat to loosen a seized wheel because heat can shorten the
life of the wheel and damage the wheel bearings. If the wheel cannot be removed by
hand, use a wheel puller to remove the seized wheel.
Remove the wheel and tire assembly.
zRemove the wheel nuts.
z Remove the wheel and tire.

Installation
1. WARNING: When a wheel is installed, always remove any corrosion, dirt or foreign
material present on the mounting surfaces of the wheel and the surface of the wheel hub,
brake drum or brake disc that contacts the wheel. Installing wheels without correct
metal- to-metal contact at the wheel mounting surfaces can cause the wheel nuts to
loosen and the wheel to come off while the vehicle is in motion, causing loss of control.
Position the wheel and tire on the vehicle.
2. CAUTION: Failure to tighten the wheel nuts in a star pattern can result in high brake
disc runout, which will speed up the development of brake roughness, shudder and
vibration.
Install the wheel nuts hand- tight, then lower the vehicle. Tighten the wheel nuts to specification
in a star- pattern sequence.
3. Install the center cap, if so equipped. Klj . 2 ba
