rod is not unusual and does not affect performance.
LOWER CONTROL ARM
The lower control arm if damaged, is serviced only
as a complete component. Do not attempt to repair or
straighten a broken or bent lower control arm. The serviceable components of the lower control
arm are, the ball joint assembly, and both pivot
bushings. The service procedure to replace these com-
ponents is detailed in the specific component sections
of this group.

joint housing until it is squarely seated against top
surface of control arm as shown in (Fig. 15).
SWAY BAR
The sway bar interconnects the front lower control
arms of the vehicle and attaches to the crossmember
(Fig. 1). Jounce and rebound movements affecting one
wheel are partially transmitted to the opposite wheel
to stabilize body roll. Attachment to the crossmember, and front lower
control arms is through rubber-isolated bushings. All
parts are serviceable, and the sway bar to crossmem-
ber bushings are split for easy removal and installa-
tion. The split in the sway bar to crossmember
bushing should be positioned toward the front of the
vehicle.
LOWER CONTROL ARM SWAY BAR RETAINER ATTACHMENT HOLE THREAD REPAIR

sway bar should be oriented toward the front of the
vehicle (Fig. 16)(3) Position bushing retainers on lower control arms
and install bolts (Fig. 16). (4) With lower control arms raised to design height,
tighten all retainer attaching bolts to 70 N Im (50 ft.
lbs.) torque. (5) Lower vehicle.
KNUCKLE (FRONT SUSPENSION)
The front suspension knuckle (Fig. 1) provides for
steering control of the vehicle. Supports the brake
caliper and absorbs the loads exerted during vehicle
braking. It also supports the front (driving) hub and
bearing and stub axle assembly. The front suspension knuckle also provides the abil-
ity to align the front wheels of the vehicle. This is done
by allowing for front wheel camber adjustment and the
ability for front tire Toe adjustments The front suspension knuckle is not a serviceable
component. Do not attempt to straighten or repair the
front suspension knuckle in any way. Service repair or replacement of the front (drive) hub
and bearing, can be done with the front suspension
knuckle remaining on the vehicle.
REMOVAL

washer from the front axle (Fig. 2). (2) Loosen hub nut while the vehicle is on the floor
with the brakes applied (Fig. 3). The hub and drive-
shaft are splined together through the knuckle
(bearing) and retained by the hub nut. (3) Raise and support the vehicle. See Hoisting in
Lubrication and Maintenance, Group 0. (4) Remove the wheel lug nuts, front tire and
wheel assembly and hub nut and washer. (5) Remove the brake caliper adapter to steering
knuckle attaching bolts and washers (Fig. 1). Re-
move the brake caliper and adapter from the steering
knuckle and braking disc. Support brake caliper/
adapter assembly using a wire hook and not by hy-
draulic hose (Fig. 4). (6) Remove the braking disc from the front hub/
bearing assembly (Fig. 5). (7) Remove the cotter pin and nut from the tie rod
end. Remove the tie rod end from the steering

HUB AND BEARING ASSEMBLY
The Unit III Front Hub and Bearing (Fig. 1) is used
on all Front Wheel Drive Applications. All hub and bearing assemblies mount to the steer-
ing knuckle the same way, but very by the wheel size
on the vehicle. Vehicles equipped with 14 inch wheels
have a 4 inch wheel mounting stud pattern. Vehicles
equipped with 15 inch wheels hav e a 4 1/2 inch wheel
mounting stud pattern. If a hub and bearing assembly
needs to be replaced, be sure that the replacement
assembly has the same size wheel mounting stud
pattern as the original part.
This unit is serviced only as a complete assembly
(Fig. 1). It is mounted to the steering knuckle by four
mounting bolts that are removed from the rear of the
steering knuckle (Fig. 2).

GENERAL INFORMATION
Chrysler front wheel drive vehicles use two different
driveshaft systems. Some vehicles use an equal length
system while other vehicles use an unequal length sys-
tem (Fig. 1). The equal length system has short solid interconnect-
ing shafts of equal length on the left and right sides.
The unequal length system has a short solid intercon-
necting shaft on the left side with a longer tubular or
solid interconnecting shaft on the right.
The driveshaft assemblies can be serviced in the same
manner for both systems. With the exception of a rubber
washer seal attached to the right inner (Constant Veloc- ity) C/V joint, on an equal length installation. The equal
length system also has an intermediate shaft attached to
a cardan joint (U-joint). With a stub shaft splined into
the right side of the transaxle with a bearing and
bracket assembly fastened to the right rear of the engine
block.
The driveshaft assemblies are three piece units. Each
driveshaft has a Tripod Joint, an Interconnecting Shaft
and a Rzeppa joint. The Tripod Joint is splined into the
transaxle side gear, or into the intermediate shaft on
the right side of an equal length system. The Rzeppa
joint has a stub shaft that is splined into the wheel hub.
