What is a visible sign of a leaking shock absorber?

A visible sign of a leaking shock absorber is the presence of oil or fluid on the shock body. When a shock absorber is functioning properly, it is sealed tightly, preventing fluid from leaking out. However, when the seals are compromised due to wear, damage, or age, the hydraulic fluid used in the shock can escape, leading to visible leakage on the outer surface of the shock absorber. This fluid typically appears shiny and may be a different color compared to the shock absorber itself, making it an unmistakable sign of leakage.

Identifying this leak is crucial, as it not only indicates that the shock absorber is not performing effectively but also suggests that suspension performance could be compromised, impacting ride comfort, handling, and safety.
