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.
