•For 2500/3500 4x4 series trucks, when changing the front wheel, assemble the
jack drive tube to the jack and connect the drive tube to the extension tube. Place
the jack under the axle as close to the tire as possible with the drive tubes
extending to the front. Connect the jack tube extension and wheel wrench.
• For 4x2 and 4x4 trucks, when changing
a rear wheel, assemble the jack drive
tube to the jack and connect the drive
tube to the extension tube. Place the
jack under the axle between the spring
and the shock absorber with the drive
tubes extending to the rear.
• Connect the jack tube extension and wheel wrench.
NOTE:
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.
• By rotating the wheel wrench clock- wise, raise the vehicle until the wheel
just clears the surface.
• Remove the wheel nuts and pull the wheel off. On single rear-wheel (SRW)
trucks, install the spare wheel and
wheel nuts with the cone shaped end
of the wheel nuts toward the wheel. On
3500 dual rear-wheel models (DRW)
the wheel nuts are a two-piece assem-
bly with a flat face. Lightly tighten the
wheel nuts. To avoid the risk of forcing
the vehicle off the jack, do not fully
tighten the wheel nuts until the vehicle
has been lowered.
• Using the lug wrench, finish tightening the wheel nuts using a crisscross pattern. The correct wheel nut tightness is 130 ft lbs (175 N·m) torque (1500 Series),
135 ft lbs (183 N·m) torque for 2500/3500 single-rear wheel (SRW) models, and
140 ft lbs (190 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.
• Install the wheel center cap and remove the wheel blocks. Do not install chrome or aluminum wheel center caps on the spare wheel. This may result in cap damage.
