WARNING
Make sure that your vehicle is properly
blocked and secured before you begin
installation of this lift kit.
2. Park the vehicle on a clean, dry, flat, level
surface. Block the tires so the vehicle cannot
roll in either direction.
WARNING
The Supplemental Restraint System (SRS, air
bag) must be deactivated before installation of
the lift kit to avoid accidental deployment of
the air bag while working near SRS sensors
and wiring. Do not allow anyone near the air
bag during installation of the lift kit. Accidental
deployment can result in serious personal
injury or death. Refer to your factory service
manual for the recommended procedure to
disable the SRS before installation of lift kit.
The SRS must be reactivated before driving
the vehicle.
3. Disconnect both battery cables. Be sure to
disconnect the negative cable first, then the
positive cable. Remove the airbag fuse from
the fuse box.
4. Before you begin lifting the vehicle, you
need to measure and record the bumper to
vehicle gaps and also the distance between
the cab and the bed. These dimensions will
allow you to retain the factory spacing at these
locations.
5.
4 wheel drive models only.
Remove the
four screws that mount the shift boot to the
floorboard. Pull the boot up out of the way (It
will not slip over the shift knob). Remove the
four bolts that mount the inner shift boot to the
floorboard (there are two on top and two on
the side). Carefully pull the inner boot up
through the hole in the carpeting and out of
the way. Remove the bolts that mount the shift
lever to the transfer case shift linkage.
Remove the shift lever from the linkage.
6. Remove the doorjamb scuff plates by gently
pulling until the tabs release from the holes in
the floorboard. Remove the front kick panels
by gently pulling out from the side until the
tabs release. Pull the carpeting back to
expose the cab mounting bolt in the front
floorboard. It can be loosened at this time.
7.
Super cab models only.
The rear seat
must be removed to access the rear cab
mounting bolts. Remove the nut and bolt that
mount the seat to the floorboard. Lift the seat
off the studs protruding from the floorboard
and carefully remove it from the vehicle.
Carefully pull the carpeting back to expose the
back four cab-mounting bolts (Two on each
side. One is under the seat back and the other
is just behind the front seat in the floorboard).
These can be loosened at this time.
CAUTION
Be sure that the steering shaft does not turn
independently of the steering gearbox. This
could cause the air bag system to malfunction
causing possible personal injury and damage
to the vehicle.
8. Lock the steering column so the steering
wheel cannot turn independently from the
steering shaft. Loosen and remove the bolt
that mounts the steering shaft universal joint to
the steering column under the dash. Slide the
steering shaft down from the column. Install
the female side of the steering extension to
the male shaft at the steering column. It
should only go on one way. Install the Allen
head bolt in the steering extension. Be sure
that the bolt goes through the retaining groove
on the male shaft. Tighten the Allen head bolt
securely. Do not install the steering shaft to
the extension at this time. It will be installed
after the lifting operation is complete.
9. Remove the cover over the throttle body on
the intake manifold. Loosen the clamp that
attaches the air duct to the throttle body.
Release the clamp that holds the two halves of
the air filter housing together. Remove the air
duct from the throttle body. Lay the air duct
back out of the way.
10. Remove the two bolts that mount the fan
shroud to the radiator. Pull the fan shroud up
out of the clips on the bottom of the radiator.
Lay the fan shroud over the fan away from the
radiator.
WARNING
Use extreme caution when working with the
engine cooling system. Never remove the
radiator cap from a hot radiator. Wait until the
engine and radiator has cooled and the
pressure in the system has dissipated. Use
care not to spill any antifreeze/coolant while
draining system. Antifreeze can be harmful to
the environment. Take care to store the
drained antifreeze/coolant in a place away
from children and animals. Antifreeze/coolant
can be fatal if swallowed.
11. Be sure that the radiator has cooled
sufficiently to prevent injury. Remove the
radiator cap. Drain the coolant into a clean
