Holding up your Dodge Caravan's trunk lid is no problem for your perfectly functioning trunk struts. But when old age catches up on these components, you will definitely have a lot of trouble accessing your trunk. Here are some familiar Dodge Caravan trunk strut issues:
Possibly the most obvious sign that your trunk struts are on their way out is a trunk lid that won't hold up. Your trunk struts will slowly get weaker as time passes, making it more difficult for you to tell the difference. Try popping up your trunk lid and watching it closely. If it starts to fall down bit by bit, you probably need to replace your trunk struts. If your trunk lid suddenly slams down hard on the back of your head while you're loading or unloading some things in your trunk, then you definitely need new trunk struts.
Listening for odd noises whenever you open and close your trunk can tell you if your trunk struts are still properly lubricated. To get rid of unusual squeaking noises from your trunk struts, try coating the seals and retaining bolts with some lubricant. Make sure to use a lubricant that is not silicone-based and is non-greasy, or you might damage your trunk strut's seals.
Over time, the seals in your trunk struts will give in to wear and tear, and they won't be able to hold in the mineral oil inside your trunk struts. Since mineral oil leaks are a common cause of early failure among trunk struts, worn-out multiple-lip seals in your trunk struts should be replaced at once. If your trunk strut rods are covered by a thin layer of oil, then your trunk struts are definitely leaking. Apart from replacing the seals, make sure to check for any cracks on the body of your trunk struts as well.
Check if the retaining bolts on your trunk seals are secure and tighten them if necessary. Don't forget to look for signs of corrosion on all metal parts of your trunk struts as well and clean up the corroded area with some rust inhibitor.
