3D-2 FRONT SUSPENSION
GENERAL DESCRIPTION
The front suspension is the strut type independent suspension. The upper end of a strut is anchored to the body
by a strut support. The strut and strut support are isolated by a rubber mount.
The lower end of the strut is connected to the upper end of a steering knuckle and lower end of knuckle is attached
to the stud of a ball joint which is incorporated in a unit with a suspension control arm. And this steering knuckle
is connected to the tie rod end.
Thus, movement of the steering wheel is transmitted to the tie rod end and then to the knuckle, eventually causing
the wheel-and-tire to move.
