6. Raise the vehicle by turning the
jack handle clockwise. Raise the
vehicle far enough off the
ground so there is enough room
for the compact spare tire to
fit under the vehicle.
7. Remove all of the wheel bolts.
{ CAUTION
Rust or dirt on a wheel, or on
the parts to which it is
fastened, can make wheel bolts
become loose after time. The
wheel could come off and
cause an accident. When you
change a wheel, remove any
rust or dirt from places where
the wheel attaches to the
vehicle. In an emergency, you
can use a cloth or a paper
towel to do this; but be sure to
use a scraper or wire brush
later, if needed, to get all the
rust or dirt off. See Changing a
Flat Tire on page 9-60.
8. Remove any rust or dirt from the
wheel bolts, mounting surfaces
and spare wheel.
Installing wheels with a good
metal-to-metal contact at
the mounting surface is
necessary to prevent the wheel
bolts from becoming loose.
To prevent corrosion or rust
build-up, apply a light coat of
wheel bearing grease to the
wheel hub center and to the
cone-shaped surface of each
wheel bolt at every wheel change.
