The short/long arm front suspension design allows
each wheel to compensate for changes in the
road surface level without appreciably affecting the
opposite wheel. Each wheel independently connects to
the frame by the following:
• A steering knuckle (6)
• A wheel hub (7)
• A shock absorber (26) and spring (27)
• Upper and lower ball studs (2,8)
• Upper and lower control arms (1,9)
The steering knuckle and the hubs (6,7) move in a
prescribed three-dimensional arc. The front wheels are
held in proper relationship to each other by the two
front tie rods. The front tie rods connect to the steering
arms on the knuckles and connect to the steering gear.

Springs (27) mount to the lower control arms (9).
Direct-acting shock absorbers (26) provide ride control.
The upper portion of the shock absorber connects
to the front upper shock absorber mount (28).
The upper mount (28) extends through the upper
control arm support (29) and through the center
wheelhouse. The upper mount attaches with two
bolts/screws (31) and two nuts (30).
The stabilizer shaft (16) controls idle roll of the front
suspension. The stabilizer shaft mounts to the
stabilizer shaft insulators (18). These insulators attach
to the frame side rails by the stabilizer shaft brackets.
The ends of the stabilizer shaft (16) connect to the
lower control arms (9) by the stabilizer shaft links (11 ).
These ends are isolated by bushings.
