The suspension system in your car is the main system that provides control and a comfortable ride as you drive, and the springs are a key component of the suspension.
Every time your car goes over a bump or dip in the road and even as you drive normally, the suspension springs compress and rebound constantly.
Eventually, a spring might no longer be able to support the same grueling abuse and it breaks or won’t rebound like it should and needs to be replaced.
Cars that travel on rough roads more frequently can expect spring replacement more often.
Most modern cars use coil springs at the front and rear along with struts or shocks, while trucks and SUVs may use coils in the front suspension and leaf springs in the rear suspension.
