NOTE: To avoid excessive wear  and  the necessity of rebalancing, mark and  reinstall wheels in the same location and
position as before removal. To lessen  the chance of imbalance, each wheel hub is equipped with a  guide stud to ensure
that a  removed wheel can be  reinstalled in its  original position (as when changing over to winter tires/wheels).
NOTE: Refer to page 129
 for hoisting the vehicle on a  garage lift. 
CAUTION:
The car must  not be  driven with wheels of different  dimensions or with a  spare tire other than the one  that came with
the car. The use of different  size wheels can seriously damage your car's transmission.
Correct tightening torque on wheel bolts  must  be  observed. The wheel bolts  should never be  greased or lubricated.
The extended, chromed wheel bolts  must  not be  used with steel rims, as they make it impossible to fit the hub caps. 
Installing the wheel
Clean the contact surfaces on the wheel and  hub.
Lift the wheel and  place it on the hub. Make sure that you align the wheel with the guide stud on the wheel hub prior
to installation.
Install the wheel bolts  and  tighten hand -tight. Using the lug wrench,  tighten crosswise (see illustration above) until
all bolts  are snug.
Lower the vehicle to the ground and  alternately tighten the bolts  crosswise to 100 ft. lbs. (136 Nm).
Install the wheel cap (where applicable).
