Wheels: Service and Repair
Removal
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.
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.
Penetrating oil is not effective in removing tight wheels. However, if used, apply the penetrating oil sparingly to the hub surface only.
Excessive force, such as hammering the wheel or the tire, may cause damage. Lightly tap the tire's sidewall with a rubber mallet.
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.
Use the following procedure to safely remove the wheel:
1. Tighten all of the wheel nuts on the affected wheel.
2. Loosen each wheel nut two turns.
3. Lower the vehicle onto the floor.
4. Rock the vehicle from side to side as hard as possible using one or more person's body weight to loosen the wheel.
-
Rock the vehicle from Drive gear to Reverse gear allowing the car to move several feet in each direction. Apply quick, hard Jabs on the brake
pedal in order to loosen the wheel.
Removal Procedure
1. Raise the vehicle and suitably support the vehicle.
2. Remove the hub cap.
3. Remove the wheel nuts.
4. Mark the location of the tire and wheel to the hub.
5. Remove the tire and wheel assembly.
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.
6. Clean the following components:
-
Clean the wheel nuts.
-
Clean the studs.
-
Clean the wheel.
-
Clean the rotor mounting surfaces.
