What is a sign of a failing suspension system?

A sign of a failing suspension system can indeed be identified by the use of coil springs that have been extended by spacers or blocks. When a vehicle’s suspension is functioning correctly, coil springs are designed to support the weight of the vehicle and provide stability while maintaining a proper ride height. The use of spacers or blocks to extend these springs can indicate that there may be underlying issues with the suspension system, such as worn-out springs or a modification aimed at compensating for other problems. This alteration can lead to improper weight distribution, reduced performance, and an overall decrease in ride quality, which are indicators of a failing suspension.

In contrast, well-functioning shock absorbers would not show leaks, indicating they are in good condition. Similarly, firm handling and response coupled with the ability to bounce back when pushed down suggest that the suspension system is effectively absorbing impact and maintaining stability, which are characteristics of a healthy suspension system.
