A front-end suspension system

Front-End Suspension Parts Quiz: Are You A Pro or No?

A vehicle’s suspension system is the first line of defense against abnormal driving conditions and normal wear and tear. Cars need to be responsive, reliable and durable for the long haul, and this all rests on the suspension — literally.

Front-end suspension varies from rear-end suspension by model, but let’s assume that the majority of passenger cars on the road today are also front-steering. The steering and suspension systems are intimately involved, as they work together to enable steering while also protecting components and handling vibrations and changes in terrain. A problem with one part can quickly cause damage or premature wear to others.

You might understand how important front-end suspension is for your car, but do you know the names and jobs of its different components? Take this quiz to find out.Front-End Suspension Quiz: Pro or No?
