Not trying to be terse or curt, but....

try using the search feature. Some time back there was a how-to posted on rear hatch strut replacement, complete with pictures. It may even have been one of the DIY articles under the DIY tab. Of course this was on a W124 wagon IIRC, but the process should be basically the same. I believe it entailed removal of the rear hatch liner and possible the rear header. The article is somewhere on this site but I couldn't tell you where.

Good luck.
