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 3500 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 on models 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.
• Dual wheel models require a special heavy-duty lug nut tightening adapter
(included with the vehicle) to correctly tighten the lug nuts. Also, when it is
necessary to remove and install dual rear wheels, use a proper vehicle lifting
device.
WHAT TO DO IN EMERGENCIES
• Slots in the wheels will assist in
properly orienting the inner and outer
wheels. Align these slots when
assembling 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.
