Mitsubishi Eclipse Trunk Strut

Culprits behind Mitsubishi Eclipse Trunk Strut Issues

Despite all the hard work that your Mitsubishi Eclipse trunk strut does to hold up your trunk lid, this particular component usually goes unnoticed and unappreciated until it fails completely. Gradual wear and tear makes your trunk struts more and more susceptible to failure, so consider checking up on your trunk struts if you have been using them for quite some time already. To help you find a solution for your Mitsubishi Eclipse trunk strut problems, here are some of the most common signs that your trunk struts are failing:

Trunk lid won't stay up

Easily the most common sign that your trunk struts might be needing replacement soon is a trunk lid that won't stay up. It's quite common for trunk struts to gradually lose power after several years of use. However, this can make diagnosis a little more difficult, since slow wear and tear is less noticeable than abrupt failure of the part. Usually, a trunk lid that is increasingly becoming difficult to open and close or one that slams when it closes will eventually lead to a trunk strut that is too weak to hold your trunk lid up.

Mineral oil leaks

Mineral oil leaks are also a familiar symptom of trunk strut failure, especially among gas-charged struts. Mineral oil leaks are usually caused by worn-out multiple-lip seals at the end of your trunk struts. Over time dirt and grime can collect on the seals and cause them to fail. These trunk strut seals are usually fairly easy and cheap to replace, but faulty seals can lead to total trunk strut failure if they don't get immediate attention. If you have replaced all the seals but the trunk struts are still coated by a light film of oil, try examining the body of the trunk strut for any cracks as well.

Other troubleshooting tips

Some squeaking noises from the trunk can also indicate trunk strut problems, although this is usually just a matter of lack of lubrication. To eliminate the squeaking trunk strut issue, lubricate the trunk strut mounts and seals with some non-greasy, non-silicone lubricant. Check the mounting bolts, pins, or clips for any cracks or signs of damage as well.

  • How to Extend the Life of Your Mitsubishi Eclipse Trunk Strut 27 February 2013

    Your Mitsubishi Eclipse trunk strut is a component that gradually fails over several years of use. If your old trunk struts have become too weak to prop up your trunk lid, you have no choice but to replace them. Make sure that your new trunk struts will last for as long as possible by following these maintenance tips:


    Keep your trunk strut's mounting points properly lubricated.


    Dried up and corroded mounting bolts or clips don't just make annoying squeaking sounds; they also increase the risk of your trunk lid falling off unexpectedly. Lubricate the trunk struts mounting points and the trunk lid's hinges using some white lithium grease to avoid the above scenario. Just take care not to get the lubricant onto your trunk strut's shaft to avoid damaging it.


    Regularly clean your trunk strut's shaft using only the appropriate cleaner.


    A clean trunk strut shaft plays an important role in prolonging the lifespan of your trunk strut's seals. Use a soft cloth and a small amount of wax to clean the shaft. Avoid using cleaners that are oil-based or those that contain silicone, since these types of cleaners leave your trunk strut's shaft sticky and causes it to attract more dust and other debris.


    Always replace your trunk struts in pairs.


    Although some people might think that replacing each trunk strut only when it fails is more economical, this practice is actually counterproductive. Replacing your trunk struts in pairs ensures that each side of your trunk lid gets the same amount of force. This reduces the risk of damaging the door hinges or of premature failure of your newly-installed trunk strut.


    Install your trunk struts according to the recommended position.


    Most gas-charged trunk struts should always be installed with the shaft down. Installing your trunk struts in this orientation guarantees that the trunk strut's shaft and seal gets the right amount of lubrication. This means that you get more mileage out of the seals and the shaft gets more protection from corrosion.


    Visually inspect your trunk struts for physical damage.


    Several external factors such as extreme temperatures can also cause damage to your trunk struts, so make sure to examine them from time to time for any cracks, rust, and other signs of wear. Don't forget to include the end fittings and mounting bolts or fasteners during your visual inspection.
