LOWER CONTROL ARM
DESCRIPTION
The lower control arm is mounted to the front sus-
pension crossmember using a pivot bolt through the
center of the front pivot bushing, and the front sus-
pension cradle crossmember reinforcement traps the
rear bushing in the crossmember (Fig. 1).
The lower control arm is an iron casting with two
rubber bushings and a ball joint. The lower control
arm front bushing is the spool type and is pressed
into the lower control arm. The standard (Low-line)
lower control arm rear bushing is a push-on bushing
that is pushed over a stem on the rear of the lower
control arm. The optional (High-line, Premium,
Sport) lower control arm rear bushing is a hydro-
bushing that is pressed on. It has liquid filled voids
that provide more effective dampening than the stan-
dard bushing. Vehicles with rear hydro-bushings uti-
lize a different lower control arm than vehicles with
standard bushings. They have a straight slightly
tapered round stem where the hydro-bushing is
mounted whereas the standard arm has a straight
stem with a squared knob on the end to retain the
bushing.
The lower control arm ball joint is pressed into the
outer end of the arm. The ball joint has a tapered
stud and retainer nut for fastening it to the steering
knuckle.
OPERATION
The lower control arm supports the lower end of
the steering knuckle and allows for the up and down
movement of the suspension during the jounce and
rebound travel. The lower control arm ball joint con-
nects the arm to the steering knuckle.

STANDARD PROCEDURE)
STABILIZER BAR
DESCRIPTION
The stabilizer bar interconnects both front struts of
the vehicle and is attached to the front crossmember
(Fig. 1).
Attachment of the stabilizer bar to the front cross-
member is through 2 rubber-isolator cushion bush-
ings and retainers. A double ball jointed stabilizer
bar link is used to attach each end of the stabilizer
bar to the front strut assemblies. All parts of the sta-
bilizer bar are replaceable as individual components.
The stabilizer bar to front crossmember cushion
bushings are split for easy removal and installation.
The split in the bushings should be positioned toward
the rear of the vehicle, with the square corner facing
down, when the stabilizer bar is installed.
OPERATION
Jounce and rebound movements affecting one
wheel are partially transmitted to the opposite wheel
of the vehicle through the stabilizer bar. This helps
to minimize the body roll of the vehicle during sus-
pension movement.
Connecting the stabilizer bar links to the strut
assemblies helps reduce the fore-and-aft rate of the
stabilizer bar from the rest of the front suspension.

HUB / BEARING
DESCRIPTION
The rear wheel bearing and rear wheel hub of this
vehicle are a one-piece sealed unit, or hub and bear-
ing unit type assembly (Unit III). The hub and bear-
ing is mounted to the center of the rear axle using 4mounting bolts. It has five wheel mounting studs on
the hub flange.
All-Wheel-Drive vehicles have a hub and bearing
unit with a splined hole in the center of the hub for
rear driveshaft stub axle acceptance.
Front-Wheel-Drive vehicles with antilock brakes
have an internally mounted wheel speed sensor and
tone wheel. This hub and bearing can be identified
by the rounded cap and molded in connector on the
rear of the assembly (Fig. 7). The sensor and tone
wheel cannot be serviced separately from the hub
and bearing.
OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the tire and wheel
assembly (and driveshaft on All-Wheel-Drive vehi-
cles). The five wheel mounting studs mount the tire
and wheel assembly, and disc brake rotor or brake
drum to the vehicle.
On All-Wheel-Drive vehicles, the splined mating of
the driveshaft stub axle and hub allows the drive-
shaft to rotate with the hub and wheel.
Front-Wheel-Drive vehicles equipped with antilock
brakes have a wheel speed sensor and tone wheel
mounted to the rear of the hub and bearing. The tone
wheel rotates with the hub which is sensed by the
wheel speed sensor.
DIAGNOSIS AND TESTING - HUB AND
BEARING
The bearing contained in the hub and bearing
assembly will produce noise and vibration when worn
or damaged. The noise will generally change when
the bearings are loaded. A road test of the vehicle is
normally required to determine the location of a
worn or damaged bearing.
Find a smooth level road surface and bring the
vehicle up to a constant speed. When vehicle is at a
