Anyone can diagnose these struts without any prior knowledge of how the part functions. All that is needed to know is that they hold the liftgate up securely. When they fail to keep the liftgate up unless it is pulled down to the closed position, it is time to replace them. Also, if the liftgate support struts are able to rattle against their mounting points, they will likely need replacement due to this condition. This will prevent wear from allowing the strut to separate from the mounting point.
How are Liftgate Support Struts replaced?
For nearly all liftgate support struts the replacement procedure is the same, and takes less than one minute. Some will require the removal of a fastener of some type, but most require the removal of a flat spring which is curved around the assembly. The flat spring will be located on the ball at the end of the strut, and using a screwdriver ror pick, the spring can be gently pulled back, which causes it to release the circular mounting point inside the ball. Once done, the strut pulls off, so ensure the liftgate has secondary support already in place. A broom handle does a very nice job of this at home. The new strut will pop right on without pulling the spring back, and the other end must be replaced in the same way. Ensure they are replaced as a set.
RepairPal Recommendations for Liftgate Support Strut issues
Never replace only one support strut, unless it was physically damaged by an external force. When one fails, the other must do every bit of the work for both, so replacing one will cause undue stress on the new one. The old, worn out strut will fail more quickly, and the new strut will wear twice as fast. This will lead to early replacement of three struts instead of two.

When the liftgate support struts are worn out, no one should not be allowed to stand between the liftgate and rear bumper, especially if the existing liftgate support struts can be made to stay in the opened position after a few tries. The slightest wind or jarring of the vehicle can cause the liftgate to swing down violently and crush anyone in its path. The use of a prop rod, like a strong piece of wood or a broom handle, is necessary if there will be loading or unloading done. Also, there should be someone there to hold the liftgate just in case. The weight of the liftgate is very much heavier than it seems with working support rods.
Can I replace the Liftgate Support Strut myself?
This is a simple fix for any DIYer, or just someone who does not want to spend money at the shop. With the most basic tool, a helper to hold the liftgate, and a few minutes, anyone can easily perform this task. Be aware, however, that the struts can be hard to compress once they are freed of their manufacturer packaging straps, as they are packed compressed and will extend forcefully when the straps are cut/removed.
Liftgate Support Strut Replacement Cost Estimates
The average cost for a Liftgate Support Strut Replacement is between $164 and $184 but can vary from car to car.
