4. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the nuts counterclockwise to loosen them. To get
maximum leverage, fit the wrench to the nut so that the
handle is on the right side, as shown above. Grab the
wrench near the end of the handle and pull up on the
handle. Be careful that the wrench does not slip off the
nut.
Do not remove the nuts yet ± just unscrew them about
one±half turn.

6. After making sure no one is in the vehicle, raise
it high enough so that the spare tire can be installed.
Allow for the fact that you need more ground clearance
when putting on the spare tire than when removing the
flat tire.
To raise the vehicle, insert the jack handle into the jack
(it is a loose fit) and turn it clockwise. As the jack touches
the vehicle and begins to lift, double±check that it is
properly positioned.

Before putting on the wheel, remove any corrosion on
the mounting surfaces with a wire brush or such.
Installation of wheels without good metal±to±metal
contact at the mounting surface can cause wheel nuts
to loosen and eventually cause a wheel to come off while
driving.

8. Reinstall all the wheel nuts finger tight.
Align the holes in the wheel with the bolts. Then lift up
the wheel and get at least the top bolt started through its
hole. Wiggle the tire and press it back over the other
bolts.
Reinstall the wheel nuts and tighten them as much as
you can by hand. Press the tire back and see if you can
tighten them more.

9. Lower the vehicle completely and tighten the
wheel nuts.
Turn the jack handle counterclockwise to lower the
vehicle.
Use only the wheel nut wrench to tighten the nuts. Do
not use other tools or any additional leverage other than
your hands, such as a hammer, pipe or your foot. Make
sure the wrench is securely engaged over the nut.
Tighten each nut a little at a time in the order shown.
Repeat the process until all the nuts are tight.
