be used for this vehicle.
(2) Remove lower control arm and tension strut as
an assembly from the vehicle. See Lower Control
Arm Removal in this section of the service manual
for the required removal procedure.
(3) Separate the tension strut from the lower con-
trol arm assembly.
(4) Position lower control arm in arbor press with
large end of pivot bushing inside Receiver, Special
Tool MB-990799, and special tool supporting lower
control arm (Fig. 71). Position Remover, Special Tool,
6644-2 on top of pivot bushing (Fig. 71). Using the
arbor press, press the lower control arm pivot bush-
ing out of lower control arm.
(5) Remove the pressed out lower control arm
pivot
bushing
from
the
Receiver,
Special
Tool
MB-990799 and discard.
ASSEMBLY
(1) Turn the lower control arm over in the arbor
press. Position the lower control arm so it is sup-
ported by Receiver, Special Tool, MB-990799 as
shown in (Fig. 72).
(2) Position new pivot bushing in lower control
arm so it is square with the bushing hole. Position
Installer, Special Tool 6644-1 on top of pivot bushing,
with pivot bushing setting in recessed area of
Installer (Fig. 72). Press the pivot bushing into the
lower control arm.
(3) Press lower control arm pivot bushing into
lower control arm until Installer, Special Tool 6644-1
squarely bottoms against surface of lower control

from control arm. With an open end wrench on flat of
tension strut to stop tension strut from turning.
Tighten the NEW tension strut to lower control
retaining nut to a torque of 130 N·m (95 ft. lbs.).
(5) Install lower control arm and tension strut as
an assembly back on the vehicle. See Lower Control
Arm Installation in this section of the service manual
for the required installation procedure.
LOWER CONTROL ARM TENSION STRUT BUSHING
To replace the lower control arm tension strut
bushing, the control arm and tension strut assembly
must be removed from the vehicle. The removal and
replacement of the lower control arm tension strut
bushing must be performed using an arbor press.
DISASSEMBLY
(1) Raise the vehicle using a frame contact type
hoist or supported as required using jackstands. See
Hoisting in the Lubrication and Maintenance group
of this service manual for the required hoisting or
jacking procedure to be used for this vehicle.
(2) Remove tire and wheel from vehicle.
(3) Remove lower control arm and tension strut as
an assembly from the vehicle. See Lower Control
Arm Removal in this section of the service manual
for the required removal procedure.
(4) Separate the tension strut from the lower con-
trol arm assembly.
(5) Position lower control arm in arbor press with
tension strut bushing inside Receiver, Special Tool
MB-990799 and special tool supporting lower control
arm (Fig. 75). Position Remover, Special Tool, 6644-4
on top of tension strut bushing (Fig. 75). Press
Remover, Special Tool, 6644-4 down through the ten-
sion strut bushing until the arbor press can push it
no farther. As Remover, Special Tool 6644-4 is
pressed down through tension strut bushing it will
cut the bushing into two pieces.
(6) Remove lower control arm assembly from arbor
press. Remove pieces of tension strut and Remover,
Special Tool 6644-4, from lower control arm.
ASSEMBLY
(1) Thoroughly lubricate the replacement tension
strut bushing, lower control arm and Installer, Spe-
cial Tool 6644-3 using Mopar
t Rubber Bushing
Installation Lube, or an equivalent.
(2) By hand, install tension strut bushing into
large end of Installer, Special Tool 6644-3. Press
bushing into installer as far as it will go by hand.
(3) Position lower control arm in arbor press, so
tension strut hole in lower control arm is centered on
Receiver, Special Tool MB-990799 (Fig. 76). Position
Installer,
Special
Tool
6644-3
with
previously
installed bushing, inside of tension strut bushing
hole in lower control arm (Fig. 76). Position Installer,
Special Tool 6644-2 on top of tension strut bushing
(Fig. 76). Using the arbor press, press the tension
strut bushing into the lower control arm. As the
bushing is being pressed into the control arm a pop
will be heard. When the pop is heard Installer, Spe-
cial Tool 6644-3 will slightly move up off the control
arm. At this time remove the control arm assembly
from the arbor press and pull Special Tool 6644-3 off
the tension strut bushing in the control arm. Tension
strut bushing is now installed.
(4) Install tension strut into the tension strut
bushing in lower control arm. Position tension strut
in lower control as shown in (Fig. 77) with word
FRONT stamped in tension strut positioned away
from control arm. With an open end wrench on flat of
