Has anyone else dealt with a 1995 era e320 wagon tailgate struts losing their ability to hold up the tailgate? It is kind of irritating having it land on my head when it is cold out and does not watn to stay up. I do not see any obvious strut to replace. Is there a heavy duty spring buried inside that I can get to to replace? Any work arounds? Doesn't have to be pretty.

Thanks very much,
