7. Install wheel center cap (if equipped) and remove wheel blocks. Do not install chrome
or aluminum wheel center caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the jack will not lower by turning the
dial (thumbwheel) by hand, it may be necessary to use the jack drive tube in order
to lower the jack. Stow the replaced tire, jack, and tools as previously described.
9. Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do not substitute with chrome plated
wheel nuts.
Hub Caps/Wheel Covers
• The hub caps must be removed before raising the vehicle off the ground.
• For single rear-wheel (SRW) models, use the blade on the end of the lug wrench
to pry the hub cap off. Insert the blade end into the pry-off notch and carefully pop
off the hub cap with a back-and-forth motion.
• On models with dual rear wheels (DRW), you must first remove the hub caps. The jack
handle driver has a hook at one end that will fit in the pry off notch of the rear hub
caps. Position the hook and pull out on the ratchet firmly. The hub cap should pop off.
The wheel skins can now be removed. For the front hub cap use the blade on the end
of the lug wrench to pry the caps off. The wheel skin can now be removed.
• You must use the flat end of the lug wrench to pry off the wheel skins. 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.
Dual Rear Wheels
• Dual wheels are flat mounted, center piloted. The lug nuts are a two-piece
assembly. When the tires are being rotated or replaced, clean these lug nuts and
add two drops of oil at the interface between the hex and the washer.
• Slots in the wheels will assist in prop-
erly orienting the inner and outer
wheels. Align these slots when assem-
bling the wheels for best access to the
tire valve on the inner wheel. The tires of
both dual wheels must be completely off
the ground when tightening to insure
wheel centering and maximum wheel
clamping.
