A vehicle’s tailgate is opened and closed frequently, especially in SUVs, hatchbacks, and other vehicles with rear access panels. The gas spring or lifter assembly inside the tailgate helps support its weight and provides controlled movement during opening and closing.
Like other mechanical components, a tailgate lifter can gradually lose performance because of regular use, environmental exposure, seal wear, or physical damage. Recognizing the early signs of failure can help prevent sudden closure and make vehicle operation safer.
Here are five common signs that your vehicle’s tailgate lifter may need replacement.
One of the clearest signs of a worn lifter is when the tailgate cannot remain in the open position.
A properly functioning gas spring provides enough outward force to support the tailgate after it has been opened. If the tailgate starts dropping slowly or closes on its own, the lifter may no longer be producing sufficient force.
This can happen when the gas pressure inside the cylinder decreases over time. Since the lifter is designed to assist with the weight of the tailgate, reduced pressure can affect its ability to hold the panel securely.
A tailgate that does not stay open should not be ignored because it can close unexpectedly while someone is loading or unloading the vehicle.
If these symptoms appear, the lifter assembly should be inspected.
Another common warning sign is increased effort when opening the tailgate.
A properly functioning gas spring assists the user by providing controlled outward force. When the lifter begins to lose its effectiveness, more of the tailgate's weight has to be handled manually.
