Do not diagnose from dirt alone
A light film around the seal is different from substantial oil running down a damper. Monroe distinguishes normal weepage from leakage in its inspection guidance. Compare the actual condition with the manufacturer’s examples rather than declaring every dirty shock failed.

Inspect the whole condition
Look for wet trails, accumulated fluid, shaft damage and associated handling symptoms. Photograph the area before cleaning so the technician has evidence. Do not touch hot components or crawl under a vehicle supported only by a jack.

Get a condition-based decision
Have uncertain findings assessed using the damper and vehicle guidance. A dry exterior does not prove damping performance is healthy, just as light misting alone does not prove failure. Record the diagnosis and monitor an accepted minor condition as directed instead of ignoring a developing leak.
