flat blade on the end of the lug wrench to pull the caps
off. The wheel skin can now be removed.
CAUTION!
•Use a pulling motion to remove the hub cap. Do not
use a twisting motion when removing the hub cap,
damage to the hub cap; finish may occur.
• The rear hub caps on the dual rear wheel has two
pull off notches. Make sure that the hook of the
jack handle driver is located squarely in the cap
notch before attempting to pull off.
You must use the flat end of the lug wrench to pull off the
wheel skins. Locate the hub cap pull notches (2 notches
on each cap). Insert the flat tip completely and using a
back and forth motion, loosen the wheel skin. Repeat this
procedure around the tire until the skin pops off. Replace the wheel skins first using a rubber mallet. When
replacing the hub caps, tilt the cap retainer over the lug
nut bolt circle and strike the high side down with a
rubber mallet. Be sure that the hub caps and wheel skins
are firmly seated around the wheel.

locations. Refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts of the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
