The lid on my tail trunk seems to be loose it rattles. Is there a way to tighten it up, not that we ever have overloaded it
Check to be sure neither of the trunk hinges are cracked nor the bolts are loose.Then get a set of these to support the weight on the trunk lid. http://wingriderproducts.com/
I was having that trouble too. I found the left hinge broken. It's in the shop, hope to get it back today. I also use those rubber baby buggy bumpers.......work very well!
