Service and Maintenance
CAUTION
Putting a used wheel on the
vehicle is dangerous.
You would not know how the
wheel had been used or how
many miles it had been driven.
The wheel could fail suddenly,
causing a crash.

CAUTION
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 could use a
cloth or a paper towel to do
this; but be sure to use a scraper
or wire brush later, if necessary,
to get all the rust or dirt off.
CAUTION
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.
CAUTION
Incorrect wheel nuts or improp-
erly tightened wheel nuts can
cause the wheel to become
loose and even come off. This
could lead to an accident. Be
sure to use the correct wheel
nuts. If you have to replace
them, be sure to get the right
kind.
