Tow Hooks
Two tow hooks are recessed into the front
bumper of the vehicle.
Important factors to keep in mind when
using tow hooks:
Use both tow hooks when retrieving the
vehicle.
Use a slow steady pull; do not jerk on the
hooks.
Tow hooks are not designed for towing,
only for retrieval.
Towing Vehicle with Front Wheels
Suspended
Caution
To prevent vehicle, engine,
or transmission damage, vehicles should
not be towed, even short distances,
without suspending the rear wheels or
removing the axle shafts or propeller
shaft. Axle shafts must be removed from
the rear axle assembly. The wheel hub
ends must be covered to prevent loss of
axle lubricant and entrance of
contaminants.
Caution
To avoid severe transmission damage,
when lifting and towing the vehicle from
the front, be sure to disconnect the axle
shaft at the rear axle location.
When it is necessary to tow a vehicle with
the front wheels suspended, extra
precautions must be taken to avoid
transmission or differential damage. Proceed
as follows:
Remove the axle shafts from the axle
assembly to prevent the wheels from driving
the differential and the transmission. The
wheel hub ends must be covered to prevent
loss of axle lubricant and entrance of
contaminants. If axle shafts are not
removed, removal of propeller shafts at the
rear axle will be required.
Removing the Axle Shafts Before Towing
Caution
To prevent differential and/or
transmission damage, remove the axle
shafts before towing a vehicle with the
drive axle wheels on the ground.
Caution
To prevent vehicle damage, do not use a
chisel or wedge to loosen axle shafts and
dowels. The chisel or wedge can damage
the hub, axle shafts, and oils seals.
One of the axle shafts has two sets of
splines: one set to engage with differential
side gear and one set to engage with shift
collar for the differential lock. It may be
