TOWING RECOMMENDATIONS
WARNING: DO NOT ALLOW TOWING ATTACHMENT
DEVICES TO CONTACT THE FUEL TANK OR LINES,
FUEL LEAK CAN RESULT. DO NOT LIFT OR TOW
VEHICLE BY FRONT OR REAR BUMPER, OR
BUMPER ENERGY ABSORBER UNITS. DO NOT
VENTURE UNDER A LIFTED VEHICLE IF NOT SUP-
PORTED PROPERLY ON SAFETY STANDS. DO NOT
ALLOW PASSENGERS TO RIDE IN A TOWED VEHI-
CLE. USE A SAFETY CHAIN THAT IS INDEPENDENT
FROM THE TOWING ATTACHMENT DEVICE.
CAUTION: Do not damage brake lines, exhaust sys-
tem, shock absorbers, sway bars, or any other
under vehicle components when attaching towing
device to vehicle. Do not attach towing device to
front or rear suspension components. Do notsecure vehicle to towing device by the use of front
or rear suspension or steering components.
Remove or secure loose or protruding objects from
a damaged vehicle before towing. Refer to state and
local rules and regulations before towing a vehicle.
Do not allow weight of towed vehicle to bear on
lower fascia, air dams, or spoilers.
RECOMMENDED TOWING EQUIPMENT
To avoid damage to bumper fascia and air dams
use of a wheel lift or flat bed towing device (Fig. 2) is
recommended. When using a wheel lift towing device,
be sure the unlifted end of disabled vehicle has at
least 100 mm (4 in.) ground clearance. If minimum
ground clearance cannot be reached, use a towing
dolly. If a flat bed device is used, the approach angle
should not exceed 15 degrees.
GROUND CLEARANCE
CAUTION: If vehicle is towed with wheels removed,
install lug nuts to retain brake drums or rotors.
A towed vehicle should be raised until lifted wheels
are a minimum 100 mm (4 in) from the ground. Be
sure there is adequate ground clearance at the oppo-
site end of the vehicle, especially when towing over
rough terrain or steep rises in the road. If necessary,
remove the wheels from the lifted end of the vehicle
and lower the vehicle closer to the ground, to
increase the ground clearance at the opposite end of
the vehicle. Install lug nuts on wheel attaching studs
to retain brake drums or rotors.
LOCKED VEHICLE TOWING
When a locked vehicle must be towed with the
front wheels on the ground, use a towing dolly or flat
bed hauler.

SERVICE PROCEDURES (Continued)

CAUTION: No attempt should be made to service
the headless grease fitting on the ball joint. It has
been purposely snapped off by the manufacturer to
avoid over-greasing.
STABILIZER BAR (FRONT)
Inspect for broken, cracked or distorted stabilizer
bar cushions and retainers. Inspect for worn or dam-
aged stabilizer bar links (Fig. 1).
SERVICE PROCEDURES
LUBRICATION
There are no serviceable lubrication points on the
front suspension. The front lower ball joints have
grease fittings which have had the head snapped off
by the manufacturer after they have been filled. This
has been done to eliminate the possibility of damag-
ing the non-vented seals. Grease will not leak from
the broken grease fittings. The ball joints are sealed
for life and require no maintenance.
CAUTION: No attempt should be made to replace
the ball joint grease fitting with a new fitting, then
filling the ball joint with grease. Damage to the
grease seal can result.
