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 Changing a Flat Tire on page 6-80.

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. Tighten each
wheel nut by hand.
Then use the wheel
wrench to tighten the
nuts until the wheel is
held against the hub.
