Wheels and Tires: Service and Repair
Tire and Wheel Removal and InstallationTools Required
^ J39544-KIT Complete Torque Socket Set-10 Pieces
Caution: If penetrating oil gets on the vertical surfaces between the wheel and the rotor or drum it could cause the when/ to work loose as the vehicle is driven, resulting in toss of control and an injury accident.
Notice: 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.
Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. In order to avoid expensive brake repairs, evenly tighten the wheel nuts to the proper torque specification.
Notice: Removing the wheel may be difficult because of foreign materials or a tight fit between the wheel and the hub/rotor. Slightly tap the tire side wall with a rubber mallet in order to remove the wheel. Failure to follow these instructions may result in damage to the wheel.
1. Tighten all wheel nuts on the affected wheel.
2. Loosen each wheel nut two turns.
3. Rock the vehicle from side to side in order to loosen the wheel. If this does not loosen the wheel, rock the vehicle front to back applying quick hard jabs to the brake pedal to loosen the wheel.
4. Repeat this procedure if the wheel does not break free.
Removal Procedure
1. Raise the vehicle. Support the vehicle with suitable safety stands. Refer to Vehicle Lifting.
2. Remove the wheel nuts from the tire and wheel assembly.
3. Mark the location of the tire and wheel assembly to the hub assembly.
4. Remove the tire and wheel assembly from the vehicle.
5. Clean the wheel nuts, studs and the wheel and rotor mounting surfaces.
Installation Procedure
Caution: Before installing the wheels, remove any build up 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.
Notice: A torque wrench or J39544 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 drip. Failure to follow these instructions could result in wheel, nut, and/or stud damage.
1. Install the tire and wheel assembly. Align the locating mark of the tire and wheel to the hub.
Notice: Refer to Fastener Notice in Service Precautions.
Important: Tighten the nuts evenly and alternately in order to avoid excessive runout.
2. Install the wheel nuts.
Tighten the nuts in a cries/cross pattern to 140 Nm (100 ft. lbs.).
3. Remove the safety stands and lower the vehicle.
