CONSTRUCTION
Independent suspension of front wheels permits either wheel
to absorb road irregu1arities without any effect on the opposite
wheel.
Steering is from a center point which permits smooth opera-
tion of the steering mechanism. With the center steering arm, it
is possible to eliminate frictional points which is not possible
with off-center steering.
UPPER SUPPORT ARM:
The upper support arm and pivot are one unit, the assembly
rides in bushings located at the front and rear of pivot.
The upper support arm pivot bracket is attached to the frame
side member by three bolts. The outer end is attached to the
steering spindle support by the eccentric bushing pivot bolt.
STEERING SPINDLE:
The steering spindle and the steering spin dl e support are
joined together by the pivot pin. The steering spindle support is
attached to the upper support arm by the eccentric bushing bolt
and to the lower support arm by a pivot pin which rides in a
steel bushing.
LOWER SUPPORT ARM:
The lower support arms are responsible for the vertical
movement of the front suspension. They are joined to the
steering spindle support at the outer end and to a pivot that
is bolted to the #2 crossmember at the inner end.
The coil spring seat is riveted to the lower support arm and
the top of spring fits in a recess of the #2 crossmember.
Two rubber bumpers are located on the front suspension-
one limits downward movement of upper support arm - the
other limits upward movement of the lower support arm.
BUSHINGS:
The pivot pins and steel bushings are threaded and
therefore securely bound together even though excessive
wear may take a loose fit.
Clearance between pins and bushings i s from .012 to .026
to allow for lubrication adjustment and free action.
LUBRICATION
Lubrication of threaded bushings must be thorough and
with the weight of the car off the bushings.
