²Connect the jack tube extension and wheel wrench.
Before raising the wheel off the ground, make sure
that the jack will not damage surrounding truck
parts and adjust the jack position as required.
NOTE:If the 2500/3500 bottle jack will not lower by
turning the dial (thumbwheel) by hand, it may be neces-
sary to use the jack drive tube in order to lower the jack.
4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel on 1500/2500/3500 single
rear-wheel (SRW) models. On 3500 dual rear-wheel mod-
els (DRW) the lug nuts are a two-piece assembly with a
flat face. Lightly tighten the nuts. To avoid risk of forcing
the vehicle off the jack, do not fully tighten the nuts until
the vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts
using a crisscross pattern. Correct nut tightness is 135 ft
lbs (183 N´m) torque for 1500/2500/3500 single-rear
wheel (SRW) models, and 145 ft lbs (197 N´m) for 3500
dual rear-wheel models. If in doubt about the correct
tightness, have them checked with a torque wrench by
your authorized dealer or at a service station.
