Tire Replacement

CAUTION: If penetrating oil gets on the vertical surfaces between the wheel and the rotor or drum it could cause the wheel to work loose as the vehicle is driven, resulting in loss of control and an injury accident.
REMOVAL

NOTE:
^ Penetrating oil has been found to be effective in removing tight wheels. However, if it is used it should be applied sparingly to the hub surface only.

^ Never use heat to loosen a tight wheel. It can shorten the life of the wheel, studs, or hub and bearing assemblies. Wheel nuts must be tightened In sequence and to the specified torque to avoid bending the wheel or rotor.

^ Sometimes wheels can be difficult to remove from the vehicle due to foreign material or a tight fit between the wheel center hole and the hub or rotor. Excessive force such as hammering the wheel or tire can cause damage and is not recommended. Slight tapping of the tire side wall with a rubber mallet is acceptable.

^ The wheel can be removed without damage as follows:
1. Tighten all the lug nuts on the affected wheel.
2. Loosen each nut two turns.
3. Rock the vehicle from side to side to loosen the wheel. Or rock the vehicle from forward to reverse allowing the vehicle to move several feet in each direction. Apply quick, hard jabs on the brake pedal to loosen the wheel. If that did not free up the wheel, then rock the vehicle again from side to side as hard as possible using one or more person's body weight to loosen the wheel. If the wheel is still tight, repeat the procedure.

INSTALLATION

CAUTION: Before installing the wheels, remove any buildup of corrosion on the wheel mounting surface and brake drum or disc mounting surface by scraping and wire brushing. Installing wheels with poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This can cause a wheel to come off when the vehicle is moving, causing loss of control and possibly personal injury.

NOTE: A torque wrench or a Special Service Tool (SST) J 39544 must be used to ensure that wheel nuts are tightened to specification. Never use lubricants or penetrating fluids on wheel stud, nuts, or mounting surfaces, as this can raise the actual torque on the nut without a corresponding torque reading on the torque wrench. Wheel nuts, studs, and mounting surfaces must be clean and dry. Failure to follow these instructions could result in wheel, nut, and/or stud damage.

1. Place the wheel and tire assembly in position on the hub/rotor, and install the lug nuts loosely.
2. Turn the wheel until one nut is at the top of the bolt circle, then tighten the nut just snug.





3. Snug up the remaining nuts in a criss-cross pattern to minimize runout, then tighten the nuts to 130 Nm (95 ft. lbs.) making sure to tighten evenly and alternately to avoid excessive runout.
