Thanks again for the great pics and tutorial. I'm in the same boat as you... my 1980 300SD is the first car I've ever worked on. And right now I'm in the middle of a door lock/window fail mess
I only replaced the top two. They were leaking and I could see cracks from the dry rot. I did a simple test with out the mighty vac even though I have one I didn't want to go get it . I just plugged one of the nipples (the closest one to the diaphragms you're testing) with my finger and pushed one of the diaphragms down. It went "PSSSHHHH" and I knew they were leaking. The bottom 2 were fine and looked like they had been replaced before.
