FORD 2002 Explorer v.1 - Manual (Page 220)

When one of the rear wheels is off the ground, the transmission
alone will not prevent the vehicle from moving or slipping off the
jack, even if the transmission is in P (Park) (automatic transmission)
or reverse (manual transmission).
3. Block the diagonally opposite
wheel.
4. Use the tip of the lug wrench to
remove any beauty cap by twisting
the tip under the cap. The carpeted

pad.
5. Loosen each wheel lug nut by half
a turn, but do not remove them
until the wheel is raised off the
ground.

extension on the lug nut wrench by
sliding the square end of the jack
handle through the plastic grommet
on the lug nut wrench and into the
square hole on the other side.
