What are leaf springs and how do they work?

 

 

 

 

 

 

 

 

 

Leaf springs are the foundation of the suspension and have been around since the earliest days of car making. So, what role do they play in your vehicle, and how do they work? 

The leaf spring is a simple form of suspension comprised of spring steel layers stacked on top of one another. They give support between the wheels, axles, and chassis of your vehicle. The ends of the leaf spring are attached to the chassis, and the axle is attached to the middle of the leaves. You'll primarily find leaf springs used on vehicles carrying heavier loads. You won't find leaf springs on sedans and smaller cars. Unlike the smaller shocks and struts, the vertical load is evenly spread along the leaf spring, providing an advantage. At the end of each spring lies a bushing 

There are a few varieties of leaf springs, but it's primarily broken between monoleaf springs and multi-leaf springs. As the name suggests, the monoleaf consists of a single leaf spring made from one plate that tapers out towards the end. Multi-leaf springs have leaves of different lengths stacked on top of one another to carry a heavier capacity.  

Unfortunately, with many moving wearable parts, leaf springs wear down over time. Crack on the leaves, a sagging rear, and a bottoming-out suspension are all signs of a worn leaf spring. A failing leaf spring can be tough to recognize on your own. If you believe you may have an issue, it's best to bring your vehicle to a mechanic you trust.
