lock GMC YUKON DENALI 2003 Owners Manual

Rust or dirt on the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
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.
1
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall
off, causing a serious accident.
6. After mounting the spare, put the wheel
nuts back on with
the rounded end of
the nuts toward
the wheel. Tighten
each wheel nut
by hand. Then use
the wheel wrench
to
tighten the nuts
until the wheel is held
against the hub.
7. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
8. Tighten the nuts firmly
in a crisscross
sequence as shown by
turning the wheel
wrench clockwise.
