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, 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 If a Tire
Goes Flat on page 10‑84.
8. Remove any rust or dirt from the
wheel bolts, mounting surfaces,
and spare wheel.
9. Install the spare tire.
{
WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
10. Put the wheel nuts back on
with the rounded end of the
nuts toward the wheel.
11. Tighten each wheel nut by
hand. Then use the wheel
wrench to tighten the nuts
until the wheel is held against
the hub.
12. Turn the wheel wrench
counterclockwise to lower
the vehicle. Lower the jack
completely.
