1994 CADILLAC DEVILLE engine

Downloaded from www.Manualslib.com manuals search engine The control arms and toe link are attached to the suspension support on
the inboard side, and to a suspension knuckle on the outboard side. The
hub and bearing assembly is mounted to the knuckle and
is a single,
non-serviceable unit which eliminates the need for wheel bearing
adjustment. The load leveling
(ELC) shock absorbers are attached to the
lower control arm, with
the upper end of the shock attached to the
suspension support. The springs are held in position between the lower
control arms and a pocket in the suspension support.
The suspension system also incorporates a
new damping system known as
Speed Sensing Suspension. This system controls the damping forces
in
the shock absorbers and struts, in response to various road and driving
conditions. The systems are capable of making these damping changes
extremely fast.
A computer receives inputs from vertical acceleration sensors, wheel to
body position sensors, vehicle speed sensor,
lift and dive signals. This
computer evaluates the input from these sensors, to control the damping
of each
of the struts and shocks independently to provide varied levels of
suspension control.
The system also has
the capability of providing Speed Sensitive Steering
control. This system changes your steering effort based on your vehicle
speed.

This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at a lower speed for increased
maneuverability and parking ease.
As your vehicle speed increases, the
steering effort is also increased to provide a manual
like steering feel for
maximum control and enhanced vehicle stability.
The power rack and pinion steering system has a rotary spool valve which
directs hydraulic fluid coming from the power steering pump to one side
or the other side
of the rack piston. The integral rack piston is attached to
the rack. The rack piston converts hydraulic pressure to a linear force
which moves the rack left or right. The force is
then transmitted through
the inner and outer tie rods to the steering knuckles, which turn the
wheels
If hydraulic assist is not available, manual control is maintained. However
under these conditions more steering effort
is required.
