3. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the wheel nuts counterclockwise to loosen them.
To get maximum leverage, fit the wrench to the nut so
that the handle is on the right side, as shown above.
Grab the wrench near the end of the handle and pull up
on the handle. Be careful that the wrench does not slip
off the nut.
Do not remove the nuts yet - just unscrew them about
one-half turn.
CAUTION
Never use oil or grease on the bolts or nuts. The
nuts may loosen and the wheels may fall off, which
could cause a serious accident.
