A suspension coil spring is a strong metal spring which is located in the front of the vehicle. Its primary function is to absorb the shock transferred to the vehicle when it drives over bumps in the road. The suspension coil spring works by compressing when the vehicle drives over the bump. It’s this compression that diffuses the amount of pressure that is experienced by the vehicle and smooths the ride.
suspension coil springs each have a rating, and it is important that if you replace a suspension coil spring you replace it with one of the same rating. If one suspension coil spring is damaged, both the coil springs in the vehicle should be replaced to ensure that the vehicle is driving with two matching rate springs. It is also likely that if one suspension coil spring is damaged, the other is also damaged.
If a suspension coil spring breaks, you are likely to hear it snap. This can be confirmed by examining the spring. Tyres can jump or wear unevenly if your vehicle has a broken spring.
