CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel bolts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the 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 you need to, to get all the rust
or dirt off.
8. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
Never use oil or grease on wheel bolts. If you do,
the bolts might come loose. Your wheel could fall
off, causing a serious accident.
9. Place the spare wheel on the wheel
-
mounting surface.
10. Replace the wheel
bolts. Tighten each bolt
by hand until the wheel
is held against the hub.
