Is It Necessary to Replace Springs Along with Shock Absorbers?
2 Answers
It is not necessary to replace springs along with shock absorbers, as these are two different components. When shock absorbers develop issues, springs typically do not need replacement. Springs are generally designed to last the lifetime of the vehicle, whereas shock absorbers are considered wear-and-tear parts and usually require replacement before reaching 100,000 kilometers—sooner if of lower quality. Below are symptoms of damaged springs: 1. If visible cracks are found on the springs, they should be replaced immediately. Do not underestimate this issue, as it is difficult to predict how shock absorbers will behave while driving. If hard objects become lodged in the cracks, it could pose a safety hazard. 2. Springs may also deform over time, given their constant use during driving. Although automotive springs are built to high standards, it's wise to remain cautious. This is especially true for drivers who frequently navigate mountain roads, where conditions are harsher and can accelerate wear. Regular checks for spring damage are advisable in such cases.
To be honest, I don't think it's absolutely necessary to replace the springs when changing shock absorbers, but it depends on the specific situation. With my nearly 20-year-old car, experience tells me that springs are generally more durable than shocks. As long as they aren't deformed, sagging, or cracked, replacing just the shocks is fine. However, if you frequently drive on rough roads or the car has over 100,000 kilometers, the springs may have aged and weakened—then it's better to replace them together. Better compatibility can prevent the shocks from wearing out quickly. Also, don't compromise on safety—check if the spring height is normal, and make sure the car body isn't too low when parked on level ground. If you're unsure, take it to a reliable repair shop to inspect the suspension. Don't risk big problems to save a little money.
