from the jack support tube
opening by inserting a screw
driver in the opening and prying
it out.
The tube openings are located
directly behind the front wheel
housings and in front of the rear
wheel housings.

if the vehicle is parked on an
incline.

is clear of the ground. Never start
engine while vehicle is raised.
8. Unscrew wheel bolts completely.
Keep bolt threads protected from
dirt and sand. While removing the
last bolt, hold wheel against hub to
avoid paint damage on rim.

from the sides. Keep hands
from beneath the wheels.
10. Screw the alignment bolt (1)
supplied in the tool kit into the
upper-most threaded hole.
Warning!
Always replace wheel bolts that are
damaged or rusted.
Never apply oil or grease to wheel
bolt threads.
Damaged wheel hub threads should
be repaired immediately.
