5. Screw in each wheel nut by hand until
it touches the nut seating surface on
the disc wheel, and then finger tighten
all wheel nuts until the wheel is held
in position without any looseness.
Face the tapered end of wheel nuts
inward.
6. Turn the bleeder screw of the jack
counterclockwise to lower the vehicle
slowly.
7. Tighten the wheel nuts in a diagonal
sequence and in two or three passes.
When installing a rear wheel, tighten
the nuts of the inner wheel first and
then the nuts of the outer wheel.
CAUTION
• Some impact wrenches available in
the market produce torques higher
than the maximum torque specified
for tightening the wheel nuts. If the
wheel nuts are tightened with such
an impact wrench, wheel studs
might be broken. Before using
an impact wrench, check that the
torque it produces conforms to the
specification.
• When using an impact wrench,
carefully adjust the air pressure
regulator and select the tightening
time. As a final step, tighten to the
specified torque using a torque
wrench.
