10-76 Vehicle Care
Rear Position
If the flat tire is on the rear,
position the jack under the rear
axle and get as close as
possible to the shock absorber.
5. Make sure the jack head is
positioned so that the rear axle
is resting securely between the
grooves that are on the
jack head.
6. Turn the wheel wrench
clockwise to raise the vehicle.
Raise the vehicle far enough off
the ground so there is enough
room for the spare tire to fit
under the wheel well.
7. Remove all the wheel nuts and
the flat tire.

WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
