3E-2 REAR SUSPENSION
GENERAL DESCRIPTION
Rear suspension is 5 link type of rigid axle which consists of coil springs, rear axle, shock absorbers, upper rods,
lower rods and lateral rod.
The lower rod and upper rod are connected with the axle and body by using bushes so that axle moves up and
down with bushes as their supporting points.
The shock absorber is installed between the body and axle to absorb up-and-down movement of the vehicle body.
