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.

4. By rotating the wheel wrench

clockwise, raise the vehicle until the

wheel just clears the surface.

5. 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 assembly 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.

6. Using the wheel wrench, finish tightening the wheel nuts using a crisscross

pattern. The correct wheel nut tightness is 130 ft lbs (177 N·m) torque (1500

Series), 135 ft lbs (183 N·m) torque for 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.

7. 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.

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.
