Lincoln Aviator: Front Suspension - AWD / Description and Operation - Front Suspension - Overview
Overview
The AWD front suspension consists of the following components:
-
Front and rear lower arms
-
Rear lower arm ball joints
-
Stabilizer bar, bushings and links
-
Ride height sensors (Vehicles with Continuously Controlled Damping (CCD) Suspension)
-
Passive or dynamically controlled shock absorber and spring assembly (Continuously Controlled Damping (CCD))
-
Upper control arms
-
Wheel bearings and wheel hubs
-
Wheel knuckles
-
Wheel studs
The
front suspension uses a double ball joint short long arm suspension
system. This independent-type suspension incorporates a coil over shock
assembly. The shock and spring assembly carries the sprung weight of the
vehicle. This system uses the front upper control arm for the upper
(unloaded) pivot point of the steering knuckle or spindle, and the front
and rear lower control arms for the lower (loaded) pivot points.
The
wheel hub and wheel bearing are sealed units and are serviced as
assemblies. The rear lower ball joint is integrated into the front wheel
knuckle and is serviced as part of that wheel knuckle assembly, also
the front lower ball joint is integrated into the front lower arm and is
serviced as part of that assembly.
The
vehicle has available Continuously Controlled Damping (CCD) Suspension.
The semi-active suspension damping provides improved handling, comfort
and stability by continuously adjusting the adaptive shock absorber
force to the current road and driving conditions. Sensors constantly
monitor the vehicle’s suspension motion, body movement, steering and
braking.
