Series C-P10 and C20
Series C-P10 (fig. 1) and C20 (fig. 2) trucks use a two-
link suspension with a control arm attached between each
end of the axle housing and the central area of the frame.
A single "U" bolt attaches each control arm to the axle
housing and a rubber bushing is used in connecting the
forward end of each arm to a bracket on the frame be­
tween the side rails and the tunnel.
A two-stage, pigtailed coil spring is seated and clamped
between each control arm and the frame, forward of the
axle.
Shock absorbers are installed between brackets riveted
to the frame, forward of axle housing, and brackets held
beneath the rear of each control arm by the M U" bolt.
The tie rod on the C-P10 (fig. 3) models is attached to
a stud inserted through a cast ear of the differential car­
rie r. A rubber-bushed attachment is utilized at the
frame bucket. On the C20 models the tie rod is rubber-
bushed at both ends and is supported between an axle
housing bracket and at the frame.
Auxiliary leaf springs, available as an option on C
series vehicles, are mounted rearward of the axle and
secured by a frame mounted bracket at the rear.
auxiliary spring bumper is retained by the "U" bolt at the
control arm (fig. 4).
