What is a sign that shock absorbers and struts are in need of replacement?

Replacement of shock absorbers and struts is often indicated by visible signs of wear and damage. When there are leaks present or if the bushings are damaged, it suggests that the integrity of the shock or strut is compromised, which can severely affect vehicle handling and safety. These components are crucial for maintaining control during driving and for providing a stable ride, so any external signs of failure, such as leaks, signal that it's time for those parts to be replaced.

Poor ride comfort, excessive noise during operation, and failing shock rebound tests can all be symptoms of worn-out or failing shock absorbers and struts, but they may not always provide direct visual evidence of failure like leaks or damaged bushings do. Therefore, while all these signs are important to consider, visible physical damage like leaks or bushings is more definitive in indicating a need for replacement.
