8. Lower the jack to its fully closed position. If the bottle 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 2500/3500 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 3500 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.
Wheel Nuts
• All wheel nuts should be tightened occasionally to eliminate the possibility of
wheel studs being sheared or the bolt holes in the wheels becoming
elongated. This is especially important during the first few hundred
miles/kilometers of operation to allow the wheel nuts to become properly set.
All wheel nuts should first be firmly seated against the wheel. The wheel nuts
should then be tightened to recommended torque. Tighten the wheel nuts to
final torque in increments. Progress around the bolt circle, tightening the wheel
nut opposite to the wheel nut just previously tightened until final torque is
achieved. Recommended torques are shown in the following chart.
