• Hatch, liftgate, or panel that no longer stays open
• Slow or uneven opening and closing action
• Loss of controlled movement in the support mechanism
• Noise or instability from a worn gas strut

Inspect mounting points for wear before replacing the strut, and confirm the part number 4B-943850 against the vehicle’s original support.
