      A:

      No, 1). Coil-over shocks, like a strut, the coil wraps around the shock, but it does not generally bolt to the steering knuckle like a strut does. You must replace shocks and struts more often than coil springs, but inspect the springs when you replace any suspension components. 2). Inspect the coils every time you replace any suspension component. Ball joints, tie rod ends, idler arms, pitman arms and control arms that are compromised can all wreak havoc on the coil spring and shock or strut. 3). 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. Generally, Coil springs are much more durable than shocks and struts. 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. Since the coil spring supports the weight of the vehicle, one that is sitting below its intended specifications may very well have compromised coil springs. Also, compare the ride height side to side on the same axle. The springs are separate components, and it's not unthinkable that one side can become weak while the other is OK. While this will make one side of the vehicle sag lower, replace both in this case. Always replace shocks, struts, coil springs in sets rather than individually.
