Stabilizer bar, bushings and links
•
Strut and spring assemblies
•
Wheel bearings
•
Wheel hubs
•
Wheel knuckles
•
Wheel studs
The front suspension uses a MacPherson strut system.
This suspension system incorporates a strut assembly
that takes the place of the upper arm and ball joint. The
strut performs the function of a shock absorber and is
encompassed by a coil spring. The strut and spring
assembly carries the sprung weight of the vehicle and
is also the pivot point for the steering knuckle.
This system uses a lower control arm and ball joint for
the lower (unloaded) pivot point of the steering knuckle.
The Focus RS has an improved front suspension system
with spring rates, bushes and anti-roll-bars all of which
are stiffer than those found in the Focus ST. Featured
