WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle.
Always stow the jack parts and the extra tire and
wheel in the places provided.
7. Remove wheel blocks. Do not install chrome or alu-
minum 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 (thumb wheel) 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
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 cap off.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate 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
of operation to allow the wheel nuts to become properly
set. All nuts should first be firmly seated against the
wheel. The nuts should then be tightened to recom-
mended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening
