I received the following question in one of the forums I help moderate: "I have 137,000 miles on my car. I've heard that some people experience sagging springs. Under what conditions, if any, do springs wear out and how can I tell other than a lower ride height?"
Springs support the weight of a vehicle and over time can certainly sag and result in lowered ride height and reduced body control. While you may never "need" to replace springs (short of one being broken) on your vehicle, 137,000 miles is quite some time for the Original Equipment. You would likely see a noticeable improvement by replacing your springs after this amount of driving and time supporting the vehicle's weight. While you're replacing these suspension components, consider the Eibach Pro-Kit Spring Set.
Below are a few areas that will improve by replacing worn out springs with a new set of lowering springs:
- No more bottoming out
- Reduced body roll
- Reduced pitch and dive when braking and accelerating
- Better handling and steering feel
