stud of the ball j o i n t is attached to the steering
knuckle using a castle n u t and cotter p i n .
The ball j o i n t is not a replaceable component of the
upper control arm. I f the ball j o i n t is found to be
defective, i t w i l l require- that the entire upper control
a r m assembly be replaced.
Due to the upper control a r m being made of a l u m i -
n u m and the ball j o i n t being made of steel, (dissimi-
lar metals) corrosion may occur between the pieces.
For this reason, the upper ball j o i n t has a corrosion
preventitive coating applied to i t .

1ALL JOINT LOWER CONTROL ARM
The ball j o i n t (Fig. 7) is pressed into the lower con-
t r o l a r m and uses a tapered stud for attachment of
the ball j o i n t to the steering knuckle. The tapered
stud of the ball j o i n t is attached to the steering
knuckle using a castle n u t and a cotter p i n .
Due to the lower control a r m being made of alumi-
n u m and the ball j o i n t being made of steel, (dissimi-
l a r metals) corrosion may occur between the pieces.
For this reason, the lower ball j o i n t has a corrosion
preventitive coating applied to i t and a corrosion pre-
vention gasket is used between the ball j o i n t and the
lower control a r m (Fig. 7).
STEERING KNUCKLE
The steering knuckle (Fig. 8) used on the Viper is a
one piece a l u m i n u m casting. The steering knuckle

HUB/BEARING
The wheel bearing used on the front of this vehicle
is the combined hub/bearing u n i t type assembly (Fig.
9). This u n i t assembly combines the front wheel
m o u n t i n g hub (flange) and the front wheel bearing
into a one piece u n i t . The hub/bearing assembly is
mounted to the steering knuckle and is retained by
four m o u n t i n g bolts accessible from the back of the
steering knuckle. The hub/bearing u n i t is not service-
able and must be replaced as an assembly i f the
bearing or the hub is determined to be defective. The
wheel mounting studs are the only replaceable com-
ponent of the hub/bearing assembly.
