Front Position — 1500 Models Front Position — 2500 Models
Front Tire Flat: If the flat tire is on a front tire of the
vehicle, you will need to use the jack handle and only
one jack handle extension. Attach the wheel wrench
to the jack handle extension. Attach the jack handle
to the jack (A). Position the jack on the frame behind
the flat tire where the frame sections overlap. Turn
the wheel wrench clockwise to raise the vehicle.
Raise the vehicle far enough off the ground so there
is enough room for the spare tire to clear the ground.
