10-76 Vehicle Care
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.
9. Put the wheel nuts back on with
the rounded end of the nuts
toward the wheel. Tighten each
wheel nut by hand until the
wheel is held against the hub.
10. Turn the jack handle
counterclockwise to lower the
vehicle. Lower the jack
completely.
Warning
Wheel nuts that are not tight can
work loose. If all the nuts on a
wheel come off, the wheel can
come off the vehicle, causing a
crash. All wheel nuts must be
properly tightened. Follow the
rules in this section to be sure
they are.
Warning
If wheel studs are damaged, they
can break. If all the studs on a
wheel broke, the wheel could
come off and cause a crash.
If any stud is damaged because
of a loose-running wheel, it could
be that all of the studs are

damaged. To be sure, replace all
studs on the wheel. If the stud
holes in a wheel have become
larger, the wheel could collapse in
operation. Replace any wheel if
its stud holes have become larger
or distorted in any way. Inspect
hubs and hub piloted wheels for
damage. Because of loose
running wheels, piloting pad
damage may occur and require
replacement of the entire hub, for
proper centering of the wheels.
When replacing studs, hubs,
wheel nuts or wheels, be sure to
use GM original equipment parts.
