REAR SUSPENSION

DESCRIPTION AND OPERATION

REAR SUSPENSION

The rear suspension consists of an axle with trailing arms and a lateral rod, two coil springs, two shock absorbers, two upper spring seats, and two bump stoppers. The axle structure maintains the relationship of the wheels to the body.
Each coil spring is retained between a seat in the underbody and a seat welded to the top of the rear axle.
