Diagnosis And Testing - Shock Absorber
WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
Inspect the shock absorber for damage and evidence of fluid running from the upper end of the fluid reservoir. (Actual leakage will be a stream of fluid running down the side of the reservoir tube and dripping off lower end of unit). A slight amount of seepage between the shaft and shaft seal is not unusual and does not affect performance of the shock absorber.
