3308532 - 4420D rear suspension axle/crossbeam

CROSSMEMBER

Made from aluminium alloy it is connected to the bodyshell via flexible bushes.It supports the track control arm, the camber control rod, the toe in control rod and the anti-roll bar.It is the component where the main forces exchanged between the wheels and the road are discharged. For this reason its shape has been designed optimizing the distribution of the material in order to satisfy the requirements of lightness and resistance.

STEERING KNUCKLE

It is made from spheroid cast iron and is the most stressed component.In effect, through the wheel bearing, the brake caliper, the spring/shock absorber assembly mounting, the anti-roll bar mounting, in addition to the mountings for all the arms, it acts as a true collector - distributor of all the forces acting on the suspension.
