You may have missed the post a few pages back. I don't remember who told me how to do this. It works every time without stressing the pad flaps and without frustration and litany of expletives. Turn the 840 pad flaps inside out, position the pad against the baffle, and roll the flaps back over the cups. Hold the sections you've rolled over onto the cups in place as you work your way around.
I did not notice that but i will try it later. Do these pads get easier to put on over time or will it always be this difficult? I do plan on doing mods on them since they are pretty much stock outside of me removing the double sided tape on one side. I'm going to do the other side later when I get home.
