VEHICLE HEIGHT MEASURMENTS
This suspension system was developed using a 295 - 65 R20 tire with 20” x 9” wheel and a
offset of +25. If wider tires are used, offset wheels may be necessary and trimming may be
required. Factory wheels can be used but are not recommended with tires over 11” wide. The
stock spare rim can be run in an emergency. Please note that if running the spare factory tire, it
is done for short distances and a speed not to exceed 45mph or damage to differentials may oc-
cur.

Park vehicle on a clean flat surface and block the rear wheels for
safety. Engage the parking brake.
Record the stock vehicle measurements on both the front and the
rear, this will provide a guideline on vehicle rake and lift height.
Measure from the center of the wheel up to the bottom edge of the
fender well opening and record on the chart provided on page 2.
Disconnect the vehicle power source at the ground terminal on the
battery.
Lock the steering wheel in the straight forward position with the col-
umn lock or steering wheel locking device.
Raise the front of the vehicle and support with jack stands at each
frame rail behind the lower control arms.
***2011 and newer models equipped with EPAS (Electronic Power
Assist Steering), disconnect the power steering control module to
avoid arching of the contacts in the internal power relay from a ham-
mer blow or impact wrench.***
Raise the front of the vehicle and support with jack stands at each
frame rail behind the lower control arms.
Remove the front wheels. (Fig 1)
Disconnect the ABS connectors in the engine compartment. Driver
side is by the air box and the passenger side is next to the battery.
(Fig 2, 3)
Remove the brake line brackets and ABS wires from the knuckle and
frame. Make sure to hang ABS wire out of the way in a safe location
so as not to damage the wire when removing the strut. (Fig 4, 5)

Remove the axle nut cover, and remove the axle nut. (Fig 7)
Place a suitable jack under the lower control arm for support. Re-
move the tie rod end nut. Strike the tie rod boss with a dead blow
hammer to dislodge the taper and remove the tie rod end from the
knuckle. (Fig 8)
Loosen but do not completely remove the upper ball joint nut, upper
and lower control arms. Strike the ball joint boss with a dead blow
hammer to release the taper from the knuckle.
Supporting the knuckle, remove the ball joint nut completely. Gently
swing the knuckle out and away from the frame while pulling the
axle out of the hub assembly. Be extra careful not to damage the vac-
uum actuator in the process. The actuator is made of plastic on the
inside and is easily broken or damaged. Also watch the brake lines
and ABS wires for over extension. Do not allow the knuckle to pull
on the brake lines tight. Make sure there is enough slack when lower-
ing the control arm down. (Fig 9)
Remove the sway bar end link and lower strut mounting nuts from
the lower control arm. Lower the control arm with the jack to release
the strut. (Fig 10)
Remove the upper strut mounting nuts. Remove strut assembly from
vehicle. (Fig 11)
Install the strut spacer onto the strut using the supplied 10mm flange
nuts. Torque to 30 ft-lbs. (Fig 12)
Making sure not to damage the studs, put the lower strut studs into a
suitable vice and rotate the lower sleeve in the strut by pressing on
the top of the strut the opposite direction of the original lean. You are
going to install this strut assembly back into the vehicle 180 degrees
from the original orientation and will need the studs on the bottom of
the strut to lean the opposite direction. (Fig 13)

Though this step is not necessary, to ease reassembly to lower control
arm, clamp the lower mounting pin in a suitable vice and remove the
studs from the pin. Strike the end of the stud with a dead blow ham-
mer until removed from the pin. Take care not to damage the threads.
(Fig 14)
Rotate the strut 180 degrees from the factory orientation and install
the strut with the offset studs to outside of the vehicle as stamped
onto the spacer using the factory hardware. Do not tighten at this
time.
Raise the lower control arm assembly to the strut and install the
lower pins into the control arm. You will have to use the factory nuts
to “press” studs back into the pin. Tighten the nuts until the stud is
seated completely into the pin. Once seated, loosen again so the nuts
can be properly torqued. If you have not removed the studs in the
previous step, it will take some effort to line everything up but it will
go together. Install the lower strut mount and sway bar end link to the
lower control arm using factory hardware. Torque lower strut mount
to 110 ft-lbs. Torque the sway bar end link to 40 ft-lbs.
Using the jack, raise the control arm and knuckle up towards the up-
per ball joint while lining the axle up through the hub assembly being
careful not to damage the vacuum actuator. Continue to raise the
lower control arm until the upper control arm can be attached to the
knuckle using the factory hardware. Do not tighten at this time. (Fig
15, 16)
***Very important*** To avoid damage to the vacuum actuator,
these steps must done with major caution. Hold the axle and rotate
the hub assembly while pulling outwards on the axle to engage the
splines in the actuator to the splines on the axle. Once the splines are
engaged, the axle will “pop” through the hub assembly. When the
axle is seated you will be able to see the shoulder of the axle through
the hub. If this shoulder is not visible, keep rotating the hub until it
is. The shoulder will be 2mm under the mounting surface of the nut
in the hub when properly seated. Install the axle using the factory
hardware. Torque to 20 ft-lbs. (Fig 17, 18)
