3 Suspension system perform 6 basic functions: Maintain correct vehicle ride heightReduce the effect of shock forcesMaintain correct wheel alignmentSupport vehicle weightKeep the tires in contact with the roadControl the vehicle's direction of travel
5 Dependent Front Suspension Dependent front suspension uses a solid axle. Uses one steel or aluminum beam extending the width of the vehicle. The beam is held in place by leaf springs.solid axle is only used on heavy trucks, and off-road vehicles
6 Independent Front Suspension Developed in the 1930's to improve vehicle ride control and riding comfortwheels to respond individually to road conditionssprung weight is reduced, creating a smoother ride.Twin I-Beam, Type 1 Coil Spring, Type 2 Coil Spring, Torsion Bar, Double Wishbone,
7 Twin I-Beam similar to the solid axle improves ride and handling load carrying abilityused on pickups, vans and four-wheel drive vehicles.

9 Type 2 Coil Spring coil spring is mounted on the upper control arm top of the spring is attached to the frame.upper ball joint receives the weight of the vehicleand the force of the coil springmakes it the load carrier
10 Torsion Bar no coil or leaf springs supports the vehicle weight and absorbs the road shockperforms the same function as a coil spring:supports the vehicle's weight
11 Double Wishbone type of strut suspension space saving benefits of a strutof the parallel arm suspensionmore aerodynamic hoodlineportion of the strut forms a wishbone shapedoes not rotate when the wheels turn
