Any given one of these symptoms can creep up subtlely and indicate an advanced problem by the time they come to your attention. It's essential that you act on the matter the moment you notice one of these symptoms. Shop Coil Springs. Coil springs and shocks are the critical suspension components in any truck where coil springs are used instead of leaf springs. For the truck to ride at an even level and support its own weight, the coil springs must remain in optimal condition throughout the time that you own and operate the vehicle.
When coil springs go bad, it can cause a host of issues that are discomforting as well as dangerous. Without a set of coil springs that function and provide sufficient suspension for the weight of the truck, the movements of the vehicle are bound to become increasingly unstable and abrupt.
It's crucial to understand the answers to some of the most commonly asked questions about coil springs. Here are some FAQs and our answers. There really is no set timeframe at which coil springs expire. A lot of coils last for the life of a vehicle, while others break down sooner.
Coil springs rarely break, but they can seriously wear down over time when a truck is driven in hazardous environments with endless amounts of water and dirt kick-up. It would be very dangerous to drive a vehicle with a broken coil spring. Look for solutions before operating the vehicle again. Prolonged and persistent exposure to water can cause a spring to rust. Likewise, constant overload of a vehicle can also wear down a spring.
It's important to use strong coil springs. The purpose of a set of coil springs is to balance the weight of the truck along the underside, which bears the lion's share of weight in any truck. Without these springs, the truck is liable to sag downward, especially if the truck is loaded to its full weight capacity. When your truck starts to sag, the problem can become noticeable in several ways. While the sagging might be subtle at first, you could eventually start to feel it when you sit in the driver's seat.
If it feels as though you're leaning as you drive the vehicle, that feeling is likely the result of sag. Sagging can also become noticeable from a visual perspective when you park the truck on a flat road or driveway. If you see a slight downward tilt between the front and rear bumper as you view the vehicle from its side, it's likely the result of weakened coil springs.
If the truck is slouched even when the back is empty, there's definitely a problem with the suspension. The springs are intended to give an extra bit of lift in the back.
The extra lift is designed to prevent sag once the truck is loaded. As such, an empty truck should have a slight bit of rear lift, while a loaded truck should be flat.
Slouching of any sort generally means suspension trouble. In some cases that involve issues with the suspension, the sagging will be more pronounced on one side. This symptom would indicate that the coil spring at one end is more worn than the other. In any event, vehicle sagging is an issue that needs to be fixed the moment it comes to your attention, especially if the problem is obvious when the truck is empty. If you procrastinate on correcting this situation, the weight of the vehicle is liable to ruin the axle.
When coil springs deteriorate and ultimately weaken a truck's suspension system, the brunt of excess weight is generally felt by the rear tires. As the problem accelerates, the tires are liable to wear and strip long before you would otherwise be due for a tire change.
Of course, if the tires become stripped, they need to be replaced immediately — as would the coil springs — before you have a blowout on the road. Tire wear can also be a slower and more subtle symptom of weakened coil springs.
If the springs wear down gradually, the weight distribution on the tires will slowly go off balance. Consequently, the tires will be pressed against the road at incorrect angles and slowly become misaligned. Keep in mind that the truck and its tires and suspension system are designed for specific weight balances and distributions. You must replace shocks and struts more often than coil springs, but inspect the springs when you replace any suspension components.
Coil springs can and will become compromised after time. However, depending on their application to the vehicle, many coil springs can last the lifetime of the vehicle. There really is no expiration date on coil springs, but there are a few things to check for when inspecting your suspension. While coil springs support the weight of the vehicle, it's the shocks' or struts' job to prevent the bouncing. Jounce the front suspension and the rear, for that matter and count how many bounces occur after you release the vehicle.
Two or more full bounces means weak shocks or struts. But what caused it? Age is likely the determining culprit. Coil springs are much more durable than shocks and struts, and many times replacing the shocks or struts will return the vehicle back to its original level of performance.
However, weak shocks and struts will take their toll on coil springs if left ignored for a long period of time. As the coils weaken, you will notice clunking or bottoming-out sounds, because the coils are not able to provide stability to the weight of the vehicle. In addition, weakened coils will damage shocks and struts, because their rebound distance will be much farther than the components were intended to perform.
Weak coils will compromise the ride height of the vehicle, and this symptom will affect the vehicle's alignment. Measuring the ride height of the vehicle and comparing that with the specifications will help you determine whether the coils are working in conjunction with the shocks and struts.
Some vehicles have a long history of snapping coil springs. However with many coil springs the breakage occurs on the bottom coil and can not be detected unless the spring is removed from the vehicle. Then there is reality, when redoing a 30 year old truck with a bunch of miles on it, it is just a darn good idea to replace the springs.

The springs are rust free. But, this all begged the question of why? Why am I doing this? How do I know if this or any coil sprung front end needs springs or not? How do I test them? Is it the length unsprung? I would sure appreciate some help on this question and any suggestions you might have.
