When do you need to replace your coil springs?

Coil springs should be replaced if you notice signs of wear such as sagging, uneven ride height, or excessive bouncing while driving. Additionally, if you hear clunking or rattling noises when going over bumps, or if your vehicle's handling feels unstable, it's time to consider replacement. Regular inspections, especially after hitting potholes or in older vehicles, can help determine when replacement is necessary.
