Chevrolet 2007 Avalanche Owner's Manual page 525

Front Position
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 near the front body mount as
shown. 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.
