10-74 Vehicle Care
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.
10. Remove any rust or dirt from
the wheel bolts, mounting
surfaces, and spare wheel.
11. Place the spare tire on the
wheel-mounting surface.
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.
12. Reinstall the wheel nuts with
the rounded end of the nuts
toward the wheel. Tighten each
nut as much as possible using
the wheel wrench until the
wheel is held firmly against
the hub.
Use your free hand to prevent
the wheel from turning while
tightening.
13. Turn the jack handle
counterclockwise to lower
the vehicle. Lower the jack
completely.
