Jacking Instructions

See the following steps for proper jacking and tire removal:

1. Remove the spare wheel, jack, and tools from storage.

2. Using the lug wrench, loosen, but do not remove, the wheel nuts by turning them counterclockwise one turn while the wheel is still on the ground. Changing a dually tire requires the lug wrench adapter.

   Note:

   If your vehicle is equipped with hub caps/wheel covers they must be removed before raising the vehicle off the ground Hub Caps/Wheel Covers — If Equipped.

   Note:

   Placement for the front and rear jacking locations are critical. Keep the jack and tools aligned while raising the vehicle to prevent tool damage. See the following images for proper jacking locations.

   CAUTION!:

   Do not attempt to raise the vehicle by jacking on locations other than those indicated in the Jacking Instructions for this vehicle.

   Front Jacking Location

   When changing the front wheel, assemble the jack driver to the jack and connect the jack driver to the extension tubes. Place the jack under the axle as close to the tire as possible with the drive tubes extending to the front. Connect the extension tubes and lug wrench.

   CAUTION!:

   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.

4. Connect the extension tubes and lug wrench.

5. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the surface.

   Warning!:

   Raising the vehicle higher than necessary can make the vehicle less stable. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire.

6. Remove the lug nuts and pull the wheel off. On Single Rear Wheel (SRW) trucks, install the spare wheel and lug nuts with the cone shaped end of the wheel nuts toward the wheel. On 3500 Dual Rear Wheel (DRW) trucks, if the outer tire is being replaced then leave the inner wheel on the vehicle. If the inner wheel is being replaced remove the outer wheel and replace the inner wheel. The wheel nuts are a two-piece assembly with a flat face. Lightly tighten the lug nuts. To avoid the risk of forcing the vehicle off the jack, do not fully tighten the lug nuts until the vehicle has been lowered.

7. Finish tightening the lug nuts. Push down on the lug wrench while at the end of the handle for increased leverage. Tighten the lug nuts in a star pattern until each nut has been tightened twice WHEEL AND TIRE TORQUE SPECIFICATIONS. If in doubt about the correct tightness, have them checked with a torque wrench by an authorized dealer or service station.

   Warning!:

   A loose tire or jack thrown forward in a collision or hard stop, could endanger the occupants of the vehicle. Always stow the jack parts and the spare tire in the places provided.

8. 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.

9. Lower the jack to its fully closed position. Stow the replaced tire, jack, and tools as previously described.

   Note:

   The bottle jack will not lower by turning the dial (thumbwheel) by hand, it may be necessary to use the jack driver in order to lower the jack.

10. Adjust the tire pressure when possible.
